Imagine if that refrigerator you bought just five years ago suddenly up and died—and not because of some technical glitch, but because the manufacturer deliberately reached out and deactivated it, permanently. You’d be furious, right? And you’d probably want a refund, too.  As wild as that scenario sounds for a major appliance like a refrigerator or a TV, it happens more often than you’d think in the smart home world. From the doomed Dropcam to the abandoned Revolv smart hub, there’s a long, sad parade of smart home devices that have turned into paperweights.    We’ve compiled a list of 12 infamous examples of killer smart home products that—for one reason or another—were abandoned by their manufacturers.  These deactivated smart home gadgets have either mostly or completely ceased to function. In some cases, the makers of these bricked devices offered refunds, or a discount on an upgraded or replacement product. But in other instances, customers were left high and dry.  Read ‘em and weep.  12 stone-dead smart home gadgets Amazon Echo Look  Launched: 2017 Original list price: $200 Date deactivated: July 24, 2020  Amazon It was a heady concept: an Alexa-powered smart camera that could scan your daily outfits and give you fashion advice. Indeed, the Echo Look was one of the original “look what Alexa can do!” devices, predating such out-there Alexa gadgets as the Echo Loop (Alexa on a ring) and the Amazon Astro (Alexa on a robot).  But the Echo Look never really took off—in part, perhaps, because the Look’s camera lacked a privacy shutter, a minus for a device that’s supposed to sit on your bedroom dresser. In May 2020, Amazon announced that the 3-year-old Look would go dark just two months later.  Amazon did offer Echo Look owners a free Echo Show 5 in compensation, but still, the $90 smart display didn’t exactly cover the $200 asking price for the dead-as-a-doornail fashion camera.  Amazon Echo Connect  Launched: 2017 Original list price: $35 Date deactivated: February 29, 2024  Amazon Landing right around the same time as the doomed Echo Look, the Echo Connect unlocked a killer Alexa feature: the ability to make phone calls on your landline using voice commands. All you had to do was plug your landline cable into the back of the Connect box, no additional fees required.  But as landlines gave way to cell phones and Alexa gained the ability to place calls from mobile phone numbers, the Echo Connect began to look increasingly outdated, and some bad reviews didn’t help. Still, Echo Connect users were caught off guard when, in February 2024, Amazon gave them just a few weeks’ notice that the Connect would soon go dead. On the bright side, each Echo Connect owner got a $10 Amazon gift card for their trouble.  Revolv smart home hub  Launched: 2013 Original list price: $299 Date deactivated: May 15, 2016  YouTube One smart hub to rule them all? That was the idea behind Revolv, a fire engine-red gadget packed with seven wireless radios that allowed you to control smart products from different manufacturers, all from a single app.  That was, at the time, a killer concept—so killer that Nest, which had itself just been acquired by Google, snapped up Revolv’s parent company in 2014 and promptly yanked the hub from store shelves.  Initially, Nest promised to keep existing Revolv smart hubs up and running. But by early 2016, Revolv owners learned that their hubs would stop working entirely by May of the same year, leaving them stuck with $300 paperweights while scrambling for alternatives.  Iris by Lowe’s Home Automation platform  Launched: 2012 Original list price: $50 hub, $99 Security Pack (with various contact and motion sensors, plus a keypad), $129 Automation Pack (contained Security Pack components plus a smart plug and button) Date deactivated: March 31, 2019  Lowe’s Lowe’s jumped into the smart home market early, going all-in with a hub (a second-generation hub landed in 2015 as a free upgrade for original hub owners) and a variety of sensors, security cameras, smoke detectors, and other smart components.  But from the start, Lowe’s Iris platform was beset with problems, from a lengthy and bug-ridden setup process to promised features that were slow to materialize (such as professional home monitoring), while support for third-party smart brands arrived only in dribs and drabs. Lowe’s eventually rolled out a raft of welcome updates to address the lengthy list of customer complaints, but the Iris platform never truly recovered from its rocky launch.  By 2019, Lowe’s finally threw in the towel, announcing that its Iris products would stop working by March 31 of that year. While Iris users were faced with the prospect of rebuilding their smart home setups, Lowe’s at least offered to refund customers for any Iris products that wouldn’t work on any other platforms, while Samsung SmartThings stepped up to help Iris users migrate to its own smart platform.  Hive home security products  Launched: 2017 Original list price: Various Date deactivated: September 1, 2023 (Hive Leak sensor), August 1, 2025 (all other Hive security products)  Amazon UK-based Hive had big plans for the smart home back in 2017. Originally focused on smart heating and thermostats, the brand was poised to branch out into home security with the Hive HomeShield alarm and the Hive View indoor and outdoor cameras (pictured above), while the Hive Leak Sensor would keep its wireless-enabled feelers out for water leaks.  But by 2019, Hive began dialing down its smart home ambitions, first withdrawing from the U.S. and Canadian markets (Hive gave instructions to users in North America on how to dispose of its useless smart gadgets on a support page) and then announcing it would exit the home security market altogether, with its portfolio of camera and security devices slated to go dead by August 1, 2025. (The Hive Leak lost support and connectivity in 2023.) As for refunds, the options aren’t great.  Hive chose to chop the products because “as a smart technology brand in the middle of a climate crisis, we know our focus needs to change,” according to a company statement.  Samsung SmartThings first-generation Hub, ADT SmartThings Home Security & Safety System, SmartThings Link   Launched: 2014 (first-gen Hub), 2017 (ADT SmartThings Home Security & Safety System), 2018 (Samsung Link) Original list price: $99 (hub), $550 and up (ADT SmartThings Home Security kits), $40 (SmartThings Link) Date deactivated: June 20, 2021  Jared Newman / Foundry One of the biggest and most stalwart of smart home brands, Samsung SmartThings has nonetheless seen fit to turn some of its older products into paperweights.  Back in 2021, Samsung pulled support for the original SmartThings Hub from 2014—not a huge shock, given that the hub was seven years old at the time. Still, due to compatibility issues, first-generation Hub owners were faced with the prospect of recreating their smart home setups from scratch.  More vexing was the decision to axe the much newer Samsung Link (a dongle that allowed the Nvidia Shield to perform double duty as a SmartThings hub, pictured above) and the pricey ADT SmartThings Home Security system, which were (respectively) only three and four years old.  Samsung and partner ADT offered owners of their dead products a combination of refunds and discounts on newer hardware, and the SmartThings ecosystem itself lives on, centered around the SmartThings Station, Aeotec’s Smart Home Hub, and Smart Home Hub 2 (just announced at IFA in September) .  Phillips Hue Bridge (first-generation)  Launched: 2012 Original list price: Included in a $199 Hue starter kit  Date deactivated: April 2022  Signify Signify-owned Philips Hue first began selling its industry-leading smart lights way back in 2012, and the first Hue Bridge (pictured above on the right, with a big red slash through it) came bundled with three Hue bulbs. Hue discontinued the original Bridge in 2015 in favor of an upgraded (and now square) model with more robust processing power and Apple HomeKit support, but continued to keep the older Bridge operating with frequent software updates.  By 2020, however, Philips Hue announced that first-gen Bridge “no longer has the resources to guarantee the evolution of the Hue system.” While owners of the outdated Bridge could still use it locally with the Hue app (so strictly speaking, it’s not stone dead), the device lost all online services after April 2020, including out-of-home control and voice commands.  Leeo Smart Alert Nightlight  Launched: 2014 Original list price: $99 Date deactivated: Late 2019  Best Buy Released back in 2014, the Leeo Smart Alert Nightlight was a simple connected device that could listen for smoke, carbon dioxide, and water leak detectors going off. Doubling as a night light, the Leeo Smart Alert could warn you via mobile alert if it heard any home alarms blaring—and best of all, the monthly service charge was zip, a rarity in the smart home world.  Sadly, the no-cost service (meaning no recurring income for Leeo) may have sealed the fate of the Smart Alert Nightlight. After notifying customers in August 2019 that it was facing choppy financial waters (the company said it explored the possibility of imposing monthly fees, but never followed through), Leeo announced two months later that it was “unable to keep the network on.” Its internet connection gone, the Smart Alert lost all its smarts, although it could still work as a nightlight. (The color-capable light turned white once the network support shut down).  Logitech Harmony universal remotes (first-generation models)  Launched: Various dates Original list price: Various price points  Dave deactivated: March 2025  Amazon Ever since 2021, when Logitech first announced it would stop making Harmony remotes, users knew their beloved devices were living on borrowed time.  While Harmony remotes were never widely popular, they were cherished by home theater enthusiasts with multiple A/V devices to juggle. Rather than dealing with a pile of remotes on their coffee tables, they could use a single Harmony remote to control all their components.  The most powerful—and expensive—Harmony remotes could be programmed using an online database of tens of thousands of home theater products, while a Harmony desktop application allowed you to set up elaborate automations that would power up your TV, your A/V receiver, and other components in the right order, and with the correct inputs selected.  When it first announced it was discontinuing the Harmony line, Logitech (which acquired the Harmony brand in 2004) promised to keep the Harmony servers up and running for “as long as customers are using [them].”   To date, Harmony’s servers are still running, but Logitech did go ahead and cut support for two dozen of its first-generation Harmony remotes, including the Harmony 670, 720, 880 and 880 Pro, 1100i, and the Harmony for Xbox 360, while also killing off the legacy desktop app that those older remotes relied on. (Newer Harmony remotes that work with the MyHarmony website and Harmony mobile app are still functional.)  With their support cut off, older Harmony remotes can’t be reprogrammed anymore, nor can users add new devices to them or configure new automations. The remotes will still work with their last programmed configurations, but without online Harmony support, their smarts are effectively gone.  Nest Learning Thermostats (first and second generations)  Launched: 2011 (first generation), 2012 (second generation) Original list price: $250  Date deactivated: October 25, 2025  Walmart The 2011 arrival of the first Nest Learning Thermostat arguably kicked off the smart home era—and indeed, if you asked a random person on the street back then to name a smart device, the Nest thermostat would probably be the one they’d say. There have been several iterations of the Nest thermostat over the years, including new and improved Nest Learning Thermostat versions (the fourth generation is the most recent), along with a couple of budget-priced versions: the Nest Thermostat E from 2017, and the plain-old Nest Thermostat in 2020. Through it all, plenty of loyal Nest users kept using their older Nest thermostats—why fix what ain’t broke, right? But in April 2025, Google delivered a hammer blow, announcing that it would drop support for the first- and second-generation Nest Learning Thermostats on October 25, 2025. Not only would the devices stop getting software updates, they would also no longer connect to the Google Home app, nor would they be controllable remotely or by Google Assistant.   The two oldest Nest Learning Thermostats won’t go completely dead on October 25, 2025; you’ll still be able to adjust the temperature, mode, schedules, and other settings manually on the device itself, just as you would on any other dumb thermostat. But once Google cuts off support for the devices, the very quality that made those aging Nest thermostats so special—their smarts—will vanish.  It’s not all bad news for owners of the first- and second-gen Nest Learning Thermostats, however; Google has said it offer those users $130 off the purchase of a fourth-generation Nest Learning Thermostat (which is currently selling for $280). Dropcam HD and Dropcam Pro  Launched: 2012 (Dropcam HD), Dropcam Pro (2013) Original list price: $149 (Dropcam HD), $199 (Dropcam Pro) Date deactivated: April 8, 2024  Amazon Two of the original smart security cameras, the Dropcam HD and Dropcam Pro revolutionized the DIY home security market with their handsome designs, top-notch (for the time) video quality, and affordable price tags.  None of this escaped the notice of Nest, which scooped up Dropcam in 2014, just prior to Google’s acquisition of Nest.   Unlike what happened with the Revolv smart hub, Nest kept both Dropcam units operational for a decade before finally cutting off online support for both models in early April, 2024. Nest even offered the last remaining Dropcam users a free Nest Cam, provided they were Nest Aware subscribers.  Nest Secure  Launched: 2017 Original list price: $499 Date deactivated: April 8, 2024  Google The Dropcam HD and Dropcam Pro weren’t the only products that Nest reached out and killed on April 8, 2024. On the same day, the Google-owned brand also pulled the plug on Nest Secure, its DIY home security system.  Released in 2017, the Nest Secure bundle includes the central Nest Guard component, which offers an integrated keypad, siren, and motion sensor, plus two contact sensors and a pair of NFC-equipped Nest “Tags” that can arm or disarm the system with a tap.  Nest Secure garnered some admiring notices for its attractive industrial design, as well as the tight integration with Nest’s other smart home devices. But the hefty $500 price tag for just two contact sensors and an alarm was a major turnoff, and Nest discontinued Secure in 2020…right around the time that Google sunk $450 million in ADT.  As with the Dropcams, Nest Secure stopped working in April 2024, rendering its alarm and window/door sensors useless. That said, Google did offer Nest Secure users a new ADT security system worth up to $485—either that or a $200 Google Store credit. Read...

I don’t know how your tech drawers look, but mine are filled with wires I’ll likely never use again because technology has advanced quite a bit. Thankfully, USB-C seems to be here to stay since there is no wrong way to plug these things in. It’s not just smartphones, tablets, and laptops that use these, however, but also a long list of gadgets. We’ve scoured the market for hidden gems: 12 gadgets that will make you think “Wow, I didn’t know I needed that, but it will make my life so much easier!” Let’s dive in and see what cool devices you’ll be able to use your type-C cables and ports with. Wowstick 1F+ mini electric screwdriver Wowstick If you often have to fiddle around with your computer or other gadgets, this Wowstick mini electric screwdriver may be just what you need. This pen-shaped screwdriver features three LED lights so it’s easier to see what you’re working on and rotates 200 times per minute so you can finish the job faster. The screwdriver has a stylish base so you can hold it on your desk, and a whole collection of 56 aluminum alloy bits. The screwdriver can be charged via USB-C and it can last for hours. This super fun electric screwdriver usually goes for $41. Anker Nano Power Bank Anker One thing you need to have in you bag/pocket/backpack is a power bank because you never really know when your phone will fail you and cry for a recharge. Well, the Anker Nano power bank is tiny enough to fit just about anywhere. It comes with a foldable USB-C connector and a port on the side so you can charge two devices at once if you need to. The 5,000mAh capacity is just about enough for a full phone recharge, so it will be great in a pinch. It’s also only $30, but we’ve seen it as low as $16. Endoscope camera with light Ennovor Although it’s not something you’ll use every day, this Ennover endoscope camera can definitely come in handy. You just plug it in your phone, install and app, and see everything your camera does. Our team swears by it, using it for finding whatever they dropped behind the desk, while working on the car, or looking for pipe leaks. Since it has an IP67 rating, you can even plop it in your aquarium. The camera comes with a 16.4ft semi-rigid cable and several accessories, including a hook, magnet, and a mirror. You can get this one for $23 right now. Blukar flashlight Blukar I don’t care who you are—you need a flashlight. The smaller, the better, because you get to shove it into any pocket. This model from Blukar comes with a built-in 1800mAh battery that you’ll recharge with one of those many type-C cables you have in that tech drawer we were talking about. It can work for up to 16 hours on a single charge, which is pretty decent. There are four different lightning modes to cycle through, including one that will help you signal for help. Plus, one of these is only $10, so no excuse to pass on this one. Heat It insect bite healer Anyone plagued by mosquitoes in the summer will be particularly pleased with this ingenious gadget. This tiny device, which can be easily connected to your smartphone via USB-C, can significantly reduce the itching of bites and stings with targeted heat. You simply charge the small Heat It bite healer via the app and then hold it on the bite. The heat then does the rest, breaking down the proteins in the mosquito bite that cause the area to swell, itch, and hurt. A true must-have for summer, and it costs only $20. A tiny air pump Also perfect for summer is this small air pump from Cycplus, which fits in any bag while on the go. Not only can it inflate a bicycle tire in two minutes at the touch of a button, but it’s also USB-charged. According to the manufacturer, it’s suitable for mountain bikes, road bikes, motorcycles, and even cars! In addition to being an air pump, this practical gadget can also be used as a flashlight or power bank for on-the-go use — all things that come in very handy on a bike ride. And at just $57, it’s highly recommended if you need quick help with a flat tire. USB-C mini fan These little fans are also pretty ingenious; you can easily carry them in your pocket in the summer and quickly use them whenever you need them. Anyone who’s ever sat on a crowded subway train in 30-degree heat and wished for at least a little fresh air will love this gadget. The mini fan, which costs just $20, has a USB-C port and can be easily powered by power banks, computers, laptops, or USB chargers. There are even smaller and cheaper fans available that can be connected directly to your phone, costing under $10 each. But these also provide less powerful airflow, so we recommend the standalone version. Reading light with a book clamp Anyone who enjoys reading a lot, sometimes late into the night, will appreciate this little gadget: a reading lamp that you can simply clip onto your book. It may not be groundbreaking, but with a total of three color temperatures and five different light modes, you can individually adjust how much light you need for reading. The Gritin reading lamp costs just $15 on Amazon and features a 1200 mAh battery that lasts up to 80 hours depending on usage. Afterward, you can easily recharge it via USB. You can swivel the neck of the lamp back and forth as desired, and there’s even a small charging indicator. What more could you want? External DVD Drive Amicool If your laptop is like mine and lacks a DVD drive, then this little gadget will come in handy for you. This Amicool external DVD drive uses a USB-C (or USB-A) to connect to your laptop and give yout he optical drive you sometimes need. It can read and burn DVDs and CDs with ease, allowing you to install software, copy files, back up data, play games, and so on. You won’t even need to install drives as this thing is plug and play. While this thing’s usually $29, you can often get it for around $20, which is an absolute bargain. Samsung flash drive Samsung The vast majority of flash drives have a USB-A connector, but this one from Samsung has a Type-C connector. With transfer speeds of up to 400MB/s, you’ll move files around in no time. The beauty of this thumb drive is that you can even pop it in your smartphone to record 4K vids directly on it. The Samsung Type-C flash drive comes in multiple storage options, starting at 64GB and up to 512GB and they start at $14. The 256GB version, for instance, is $27 at the time of writing. Type-C microSD card reader Ugreen Most laptops nowadays don’t come with a card reader anymore (I know mine doesn’t), so finding other ways to get data off those little buggers is a must. Whether you need to pull data off your dashcam’s card or if it’s from your camera, this tiny Ugreen USB-C microSD reader will work just fine. This reader is tiny enough that you should probably put it on a keychain of some kind. If you’d rather a slightly more versatile version, Ugreen has a model that also works with SD cards and features both USB-C and USB-A connectors. Any of these will cost you less than $10, so they’re worthwhile investments. USB-C to HDMI adapter Anker If your laptop has a USB-C port but you haven’t updated your monitor in ages, your display won’t feature a Type-C port. This Anker adapter fixes this problem for you, enabling you to connect the regular HDMI cable you plug in your monitor with this gadget. The adapter supports resolutions of up to 4K at 60Hz, which is pretty awesome. This is also a nifty way to connect your phone or tablet to your monitor or TV. This thing’s $20, but we’ve seen it as low as $12. Editor’s note: This article was originally published on May 16, but was updated to include additional devices. Read...

With any luck, Arm’s new Lumex CPU platform may give us a hint at what to expect for upcoming Windows on Arm PCs: four tiers of CPU power, plus an improved ray-tracing engine and graphics upscaling. Arm says that its new Lumex C1-series chips will deliver 25 percent more performance than the Cortex X925 series of processors it launched in May 2024. Like the X925, the latest Lumex C1 cores are being optimized with 3nm process technologies in mind, with physical implementations and foundry collaborations to speed customers to market. (While Arm has hinted at building its own physical cores for years, however, company representatives would say only that it includes “near production-ready physical implementations for partners” and is “not a chip.”) The Lumex platform is Arm’s brand for smartphones. PC-specific Arm chips will be branded as “Niva” under Arm’s new naming scheme, though they will share some common features with the Lumex cores. Qualcomm, which actually makes the Arm processors, uses the “Snapdragon” brand, which will almost certainly continue. Arm chips power the vast majority of the world’s smartphones, as Arm licenses its designs to customers who can choose to bring the Arm cores to market or take an architectural license and design compatible but otherwise brand new designs of their own making. That’s the approach Apple and Qualcomm have taken — who, in addition to designing smartphones, have brought Arm into the Mac OS space as well as Windows on Arm PCs. Though Qualcomm and Arm have had their legal differences over licensing Arm’s cores — which have since been settled — an Arm representative declined to comment when asked if any ongoing legal issues would prevent Qualcomm from taking a license. Arm’s new Lumex CPU cores continue delivering doble-digit performance gains, the company said.Arm And you will, apparently, see the Lumex in more than just PCs. “So the Lumex platform is going to power flagship smartphones through to PCs and tablets,” said James McNiven, the vice president of product management for Arm, in a press briefing. Smartphones, though, have their own demands: low power, which Arm’s RISC architecture was designed for; and maximizing local AI. The Cortex C1 series includes what Arm calls Scalable Matrix Extension 2 (SME2), using the Arm v9.3 instruction set. Arm doesn’t use a dedicated NPU. Instead, it uses a technology called KleidiAI that essentially uses software libraries to address AI-specific functions inside the CPU, no matter which version of the Arm architecture is present. In the C1 CPU cluster, Arm says, you’ll see a 5X uplift in AI performance. Arm says that will increase performance on apps that always have some form of AI technology running, such as audio generation, camera inferencing, or computer vision. Specifically, Arm is claiming over 4.7 times improvement in latency, speech recognition, and classical large language model tasks, and about 2.8 times faster audio generation. The other thing Arm has been known for is that it basically pioneered the concept of performance and efficiency cores, a strategy known as “Big-Little.” But with the Lumex, that’s been taken to a new level with the addition of a new “premium” core. Now, there are four different tiers of CPU cores: the C1-Ultra, the C1-Premium, the C1-Pro, and the C1-Nano. Arm now has four CPU cores, not just two.Arm Nothing’s really changed all that much: The Ultra and Premium cores are simply two tiers of “performance” cores, while the Pro and Nano deliver different levels of efficiency. Arm executives said that the Premium core could stand in for the Ultra cores on non-flagship, cheaper devices, as it offers similar performance to the Ultra, but in a 35 percent smaller area. The C1 Pro “improves” upon the Cortex A75 in terms of performance and efficiency, McNiven said, while the Nano has the “smallest footprint” and will play a role in both flagship and entry-level devices, he said. Overall, Arm executives said that the on-device AI is three times more power efficient than the previous implementations, and the Pro is 12 percent more power efficient at the same frequency. Arm is also introducing a new GPU, the Mali G1-Ultra, which will promise 20 percent better graphics performance, twice the ray-tracing performance, and 20 percent faster inferencing for AI processing than the earlier Immortalis-G925. The Mali G1-Ultra will also consume less power, as the block is on its own power island with less leakage when idle. Specifically, Arm is claiming that frame rates on ray-traced games will be 40 percent higher than its predecessor, part of moving to a “single-ray” model for improved efficiency and more realistic lighting,” McNiven said. The new Mali core also includes upscaling — quickly rendering at a lower resolution for improved frame rate, then upscaling it for better visual quality — but it does not use the AI-generated frames of some desktop GPUs. Arm’s new Mali core should be the foundation of GPUs on smartphones and Windows on Arm PCs alike.Arm “One of the examples that we have been seeing recently was some of the new ray tracing benchmarks like [UL’s 3DMark] Solar Bay Extreme, and I think that we see there up to a doubling in performance, because it is so ray tracing heavy. So it really does depend on just the amount of ray-tracing content,” McNiven said. One idea behind the Lumex platform, executives said, was to move certain cloud-based AI functions on to the device. Specifically, a large language model in the world of Krafton’s Inzoi (a spiritual successor to The Sims) was run on-device at the GDC conference, they said, as well as a “coach” that watched you play in Tencent’s Honor of Kings and offered advice. A major online payment provider is also working to put agentic AI on device to handle payment processing during peak times, instead of committing to expensive, back-end cloud servers, said Chris Bergey, the senior vice president of the client line of business at Arm. “If your device is capable of running a large language model, you have an extra means of interacting with the game that augments your experience,” McNiven said. “But if you don’t have it, the game is still playable.” Read...

Jim Johnson has been named head of Intel’s Client Computing Group, headlining a list of changes Intel made Monday to its leadership team. As part of the moves, Intel announced the departure of Michelle Johnston Holthaus, the former co-chief executive and head of Intel Products. Johnson had served as the interim head of Intel’s CCG as Holthaus took on senior roles. Now, his official title will be senior vice president and general manager, responsible for the PC and edge ecosystems, Intel said. Johnson has worked at Intel for 40 years, including in the Technology and Manufacturing Group and the Networking and Communications Group. Intel also has named a new head of its Data Center Group: Kevork Kechichian who joins as executive vice president and general manager of the Data Center Group (DCG). Kechichian formerly was the executive vice president of engineering at Arm. Intel also said that Naga Chandrasekaran, executive vice president and chief technology and operations officer of Intel Foundry, will expand his role to include Foundry Services. The promotions and new hires come at the tail end of management shakeups dating back to last year, when Intel chief executive Pat Gelsinger was forced out of his role as chief executive and replaced with Lip-Bu Tan, a prominent leader in the EDA industry. After Gelsinger left, Michelle Johnston Holthaus and chief financial officer David Zinsner were named co-CEOs. Former Intel exec Michelle Johnston Holthaus.Mark Hachman / IDG After Tan joined, Holthaus — formerly the executive vice president and general manager of Intel CCG — was then asked to lead Intel’s products team, which also included the Client Computing Group. Holthaus served more than 30 years at Intel, and will remain a strategic adviser to the company over the coming months, Intel said. Johnson will oversee the fall launch of Panther Lake, the company’s next CPU architecture, as well as the Intel 18A manufacturing process that will form its foundation. Tan, meanwhile, is looking for customers for both Intel’s 18A and the subsquent 14A manufacturing process, which may decide whether Intel remains in silicon manufacturing or not. Read...

Pardon the pun, but oh my, has the landscape shifted in terms of robot lawn mowers. Five years ago, when I first started covering this smart home category, there were just two brands to choose from: Husqvarna and Worx. Today, there are dozen or so manufacturers vying for the mantle of best robot mower, albeit with varying success. Prices have come down dramatically, too. In the early days, you’d need to spend at least several thousand dollars for the most basic machine. These days, you can find models for smaller yards that cost $1,000 or less. And like robot vacuums, robot lawn mowers have become more sophisticated, with features such as onboard positioning to know where they are in your yard, cameras to spot obstacles, and even AI to remember the tricky parts of your yard and how to navigate them. Our top picks in robot lawn mowers Segway Navimow i110N – Best budget-priced mower for very small lawns Pros Best navigation technology in its price class No line-of-sight requirement from the mower to the GPS antenna Outstanding cutting performance Handles common yard types and terrain without issues Cons Front-wheel drive has trouble with steep slopes Inadequate cliff detection Best Prices Today: Retailer Price $1,299 View Deal Price comparison from over 24,000 stores worldwide Product Price Price comparison from Backmarket Who should buy the Segway Navimow i110? First, let us explain what we mean by “very small lawns.” In this case, we’re talking a quarter-acre or less. If you have a postage stamp-sized lawn, you probably don’t need a robot lawn mower. In any event, the $1,300 Navimow i110n is the best option in its price class. That said, this is a rear-wheel drive model that doesn’t pack enough power to handle steep slopes, so keep that in mind if your yard has steep grades. Segway Navimow i110: Further considerations While the lack of all-wheel drive held the Navimow i110n back in our tests, we were very impressed with how the Navimow navigated our yard and alternated its cutting patterns with each mowing session. It also does it quickly; we could mow nearly all of our quarter-acre lot in about 30 minutes. While we had problems keeping the Navimow from falling off our parking-strip curb, this is more of a detection issue with the vision and AI versus a fatal flaw. Since our initial review, several firmware updates have been released, including a new firmware update (version 2.2) that the company says is a fairly significant release. So those problems might be getting addressed. Read our full Segway Navimow i110N review Eufy Lawnbot E18 – Best robot mower for smaller lawns Pros Straightforward setup and mapping Delivered an even, thorough cut from the first mow Obstacle detection is promising (although it still needs work) Cons Somewhat underpowered for its size Rear-wheel drive only Underwhelming performance on slopes Best Prices Today: Retailer Price Price comparison from over 24,000 stores worldwide Product Price Price comparison from Backmarket Who should buy the Eufy Lawnbot E18? This is a great, moderately priced robot lawn mower for smaller, flatter yards up to 0.3 acres, with slopes of no more than 18 degrees. If you have a smaller yard, consider its stablemate, the Eufy Lawnbot E15, which can handle up to up to 0.2 acres of lawn (battery size is the only difference between the two models). Both machines are smallish, rear-wheel drive mowers, but don’t let their size fool you: They’re packed with smarts. The Lawnbot E18 uses computer vision to map your yard after you direct it to the areas of your yard you want it to go, which is a much simpler task than deploying a GPS antenna. I have a complex yard, and this mower completed its initial mapping quickly, even in areas with obstructed views and other obstacles. Once that was done, it delivered an even, thorough cut from the very first mow. Eufy Lawnbot E18: Further considerations The Eufy Lawnbot E15 and E18 are both rebranded TerraMow models that have been available in Europe since mid-2024, so they’ve been thoroughly tested by consumers on the other side of the Atlantic. Both Lawnbot E-series mowers might seem small compared to much of the competition—suburban and rural American yards tend to be very large—but you don’t need to own an acre or more of turf to appreciate a quality robot lawn mower. The Lawnbot E18 and E15 are both rear-wheel drive mowers, however, which explains their modest climbing performance. Read our full Eufy Lawnbot E18 review Sunseeker Orion X7 AWD – Best robot mower for mid-sized lawns Pros Best nighttime mowing experience of any mower we’ve tested Quality, even cut Handles narrow passages with ease Cons Frustrating mapping and app experience Too low profile for sharp slope transitions Best Prices Today: Retailer Price $2,299.99 View Deal Sunseeker $2399.99 View Deal Price comparison from over 24,000 stores worldwide Product Price Price comparison from Backmarket Who should buy the Sunseeker Orion X7 AWD? If you are taken aback by the high price of all-wheel drive robot mowers (typically several thousand of dollars), the Orion X7 comes in at the lower end of that range: $2,400. But the cut quality and capability of this mower is as good as other mowers that we’ve tested that are double the price. It’s AI works great. Sunseeker Orion X7 AWD: Further considerations While the mapping setup of the Orion X7 was suboptimal, we were really surprised by its vision and AI capabilities once the mower was running; they worked as advertised—even at night. The Orion X7’s obstacle-avoidance performance was the best of any robot mower we’ve tested to date. Better yet, it seemed to remember where these obstacles were during a session, unlike other mowers we’ve tested that would return to the same spot and make the same mistakes. The dual floating cutting plates give you a smooth level yard even if it’s not perfectly flat. If Sunseeker can fix the usability issues in its app, we’ll rank the Orion X7 higher. Read our full Sunseeker Orion X7 AWD review Segway Navimow X350 – Best robot mower for larger lawns Pros Excellent navigation and obstacle avoidance, day or night Automatically alternates its cutting direction Capable of handling very large yards Cons Exhibits a tendency for unpredictable behavior on slopes No onboard rain sensor Best Prices Today: Retailer Price Check Price comparison from over 24,000 stores worldwide Product Price Price comparison from Backmarket Who should buy the Segway Navimow X350? The Segway Navimow X350’s speed, combined with its 10-inch cutting radius, will make quick work of lawns up to 1.5 acres, and it will optimize the map it makes of your property so that it becomes more efficient over time. It’s also one of the quietest mowers I’ve tested, which could allow it to operate at night if you so choose. I will mention two drawbacks I encountered in my review: First, the mower doesn’t have an onboard rain sensor, so you’ll need to keep an eye on the weather. Second, this is a large mower and it sometimes had difficulty navigating tight spots in my yard. Segway Navimow X350: Further considerations The Segway Navimow X350 boasts a 10-inch wheelbase and a proprietary traction control system and onboard AI that helps it climb up to 27-degree slopes, even though it uses rear-wheel drive. It navigates using GPS tracking, which can also help you recover the mower should it ever be stolen. This mower will leave your lawn looking professionally groomed, thanks to its ability to automatically alternate its cutting direction. Read our full Segway Navimow X350 review Mowrator S1 AWD – Best non-autonomous robot lawn mower Pros 21-inch cutting radius Highly maneuverable Outstanding remote control Riding-mower build and cut quality Cons Very heavy (120 pounds) Disappointing autonomous obstacle avoidance Best Prices Today: Retailer Price $3,599.10 View Deal Price comparison from over 24,000 stores worldwide Product Price Price comparison from Backmarket Who should buy the Mowrator S1? We see the Mowrator as perfect for those who enjoy mowing their grass, but don’t care for the physical exertion—especially in the summer heat. We tested the Mowrator during a record-breaking heat wave here in the eastern U.S. and appreciated the fact we didn’t have to sweat it out to get our yard done. We couldn’t say the same about our neighbors. Mowrator S1: Further considerations The Mowrator S1 robot mower is in a class of its own, as it’s not entirely autonomous. Instead, you control it with a remote—much like one you’d use with an aerial drone or an RC car. The extent of its automation is cruise control, which only allows the mower to move in a straight line, and rudimentary obstacle avoidance. We included it on this list because everything else about this mower is top-notch. A 21-inch cutting radius is a half-foot larger than most robot mowers, and a traditional mower blade versus the razor blades on most other models provides a riding mower quality cut that has so far not been matched by any other mower we tested. And the maneuverability and all-wheel drive combined with an excellent remote control make mowing the grass fun. Read our full Mowrator S1 AWD review Other notable robot lawn mowers we’ve tested The Husqvarna Automower 435X ($1,799 street) is one of the few robot lawn mowers we’ve tested that depends on a boundary wire to keep from moving off your lawn and into your flowerbeds, the driveway, or other places you don’t want it to go. On the upside, it’s a beefy machine with all-wheel drive that can handle lawns up to 0.9 acres. The Mammotion Yuka 1500 robot mower had plenty of innovative features when we reviewed it, but that innovation came with some rough edges that dampened our enthusiasm for the machine. Likewise with the Dreame Roboticmower A1, which exhibited poor obstacle avoidance in our real-world testing. How we test robot lawn mowers We test robot mowers in as close to real-world situations as possible: this includes operating them during the day and at night and in varying weather conditions. We’ll typically cut a lawn an inch or two higher than normal before a test to help judge the cut quality and the mower’s ability to operate in taller-than-average grass. We’ll also put temporary obstacles in the yard to judge the mower’s collision-avoidance capabilities. If the mower has AI onboard, we’ll observe whether it remembers permanent obstacles.

What to look for when shopping for a robot lawn mower While there are many features to look for in a robot mower, some of which will be based on your personal preference, these five factors are the most important to consider to ensure trouble- and frustration-free operations. Run time and maximum yard size This one seems obvious, but many will look to the cheapest mower that can handle the size of their yard. That’s not the right approach. What you should do instead is opt for a model with a maximum yard size of at least 1.5 to 2 times the acreage of your yard. Our reasons for this are twofold: First, the maximum yard size is the amount your robot mower can handle in a single day, including time for charging. If you select a model with a maximum yard size close to the size of your yard, the mower will need to run 24/7 to keep up. Secondly, buying a larger-capacity mower prevents buyer’s remorse later, should you move to a larger home. There is no such thing as a robot mower that’s too big for a property, but you can end up with a robot mower that’s too small for your yard. Another benefit is total run time, as a larger mower won’t need to return to its base station and charger as frequently. Cut quality Cut quality has much to do with how the cutting plate is set up, and the methods used for cutting. Some models use a blade that’s shaped bread tag. We’ve found this style typically doesn’t cut well—or last very long. Rectangular blades are better, since the entire side cuts your grass no matter which way it’s oriented on the plate. This style of blade also lasts longer, which means you’ll need to change it out less during each mowing season. The cutting method is also important. We prefer robot mowers that follow straight lines and paths and alternate cutting directions during each mowing session. Some cheaper boundary-wire mowers mow in a random pattern within the boundary, which early in the season can leave your yard looking like you’ve forgotten how to mow. App functionality Most robot mowers have a lot of extra functionality to help you customize how your lawn is maintained. This means you’ll spend a lot of time in their apps. While some robot mower apps attempt to squeeze every possible feature into the app, we have found in most cases it is unnecessary and cluttering. The best mower apps have clean interfaces, along with clear instructions (and sometimes videos) to get you up to speed on important functionality. Collision and obstacle avoidance Early robot mowers used bumper sensors to detect obstacles. That’s no longer the case, and the best robot mowers use technologies like cameras, LiDAR, and onboard AI to detect obstacles. Opt for one of these models and you’ll spend a lot less time getting your mower out of places it shouldn’t have gone into. Artificial intelligence (AI) Artificial intelligence is a recent addition to robot mowers, and it makes boundary wire-free models much more reliable. With AI, your mower “learns” the quirks of your particular yard over time, optimizing its mowing session accordingly. One word of caution, however: not all robot mower AI is created equal. Some mowers seemed to not remember obstacles or places where they’ve frequently gotten stuck. AI is a relatively new addition to robot mowing, and some manufacturers’ claims don’t match reality. Fortunately, this is an upgradeable element—it resides in firmware—so this class of mower will improve with time. FAQ Frequently asked questions about robot lawn mowers 1. How do robot mowers work? Robot mowers come in one of two flavors, some a boundary wire to keep the mower in check, while others rely on GPS satellites and onboard vision capabilities leveraging AI to help the mower make both a visual and location-based map of your yard. If you would like to read more about this topic, read our in-depth guide. 2. Which type of robot mower should I get? Boundary wire robot mowers are far less expensive, as the mower needs fewer sensors and less brain power to ensure proper operation. But if you go that route, we strongly recommend hiring a professional to bury the boundary wire, so you’re not constantly tripping over it. That will increase the final price of your mower—by as much as several hundred dollars if it’s not already factored into the mower’s price—but it’s worth it. You should also be aware that boundary wires have finite lengths, maxing out at 1,000 to 2,500 feet, depending on the model and the quality of the wire. This won’t be an issue for most suburban and urban properties, but you might need more than one mower for a large property. For this and other reasons, we typically recommend boundary wire-free mowers, as they’re much easier to set up and don’t require a professional; it’s why all our best top picks—save one—are boundary wire-free models. 3. Why are robot lawn mowers so expensive? It depends on how you look at it. If you compare a robot mower to a traditional push mower, even a self-propelled one, robot mowers are considerably more expensive. Many robot mowers, however, are competitively priced in comparison to riding mowers, which offer much less in the way of labor savings. 4. Is the cut quality of a robot mower as good that of a traditional mower? You use a robot mower the way it’s designed to be used and its cut quality will be every bit as good as a conventional mower’s. Unlike a push or riding mower, a robot mower is designed to run multiple times a week, cutting a small portion of your grass each time. Some even alternate the direction of cut with each successive mowing session, which will prevent it from leaving lines in your grass from the mower’s wheels from passing over the same patch of grass each time. 5. What maintenance is required of a robot mower? Maintaining your robot mower is not difficult, and it’s not all that different from traditional mowers—except you won’t need to monitor and periodically engine oil; robot mowers use electric motors. You’ll want to regularly clean accumulated grass clippings and other debris from the underside of the mower. You’ll also want to keep it out of the elements as much as possible when it’s not in use. The plastic bodies of these mowers will slowly fade over time as the sun’s ultraviolet rays cause plastic to degrade and discolor. The most important difference has to do with cutting blades. Where conventional motors have thick blades that need sharpening at least once a season, most robot mowers use what look like razor blades to cut your grass. As you might expect, you’ll probably need to replace them at least twice every mowing season. Fortunately, the blades aren’t expensive, and you might find that third-party blades are even cheaper, although they might not last as long the OEM versions. Read...
