Segway Robot Mowers

The X390 is the flagship of the X3 series and the one Pro Tool Reviews ran on a multi-acre property with four zones linked by tunnels: it covered 3,300 sq ft on 16% of its 12.8Ah battery, which works out to roughly four hours of mowing and a 2.5 acre rating, with a 100 minute recharge. Everything else matches its siblings - 9.3 in cut, 2 to 4 inch heights, 60 dB, EFLS 3.0 RTK fused with three-camera visual SLAM that keeps working under trees, 300-degree obstacle recognition with night vision, and a 43.9 lb body on 10 inch wheels. Segway bundles five years of 4G service, the longest in the lineup, before the $32.90 a year renewal. At $4,499 (down from $4,999) it is expensive for a two-wheel-drive mower: the Mammotion Luba 2 AWD 10000 covers the same area with all-wheel drive and 80% slope capability for less, and the X3's 50% rating only holds up on straight climbs. Testers also note there is no physical rain sensor, the single 9.3 in disc is narrow for 2.5 acres so full cycles take days, and edges need the optional Trimmer attachment. In its favor: faster and more precise stripes than the Luba, gentler on turf, a cleaner app, and the Doodle feature for mowing patterns into the lawn. Choose it for a large, flat-to-rolling estate lawn with tree cover where positioning reliability matters more than hill climbing.

Best for Estate lawns up to 2.5 acres with tree cover and mild grades, where you want one DIY-installed mower instead of a dealer fleet.

The X350 buys you battery, not a different mower: it shares the X330's 43.7 lb chassis, 9.3 in cut, 2 to 4 inch height range, EFLS 3.0 RTK-plus-vision positioning and 300-degree camera array, but carries a 10Ah pack for about 200 minutes per charge (80 minute recharge) and a 1.5 acre rating. Segway lists it at $2,799, down from $3,499 at launch, and it includes three years of 4G before the roughly $33 a year renewal. Residential Tech Today beta-tested this exact model for a season and found the standout traits were quiet 60 dB running that allowed night mowing, reliable obstacle recognition, and confident navigation on a tree-heavy lawn - RTK antenna placement still mattered, and moving it meant remapping. Early-spring patches of thin grass confused the VisionFence boundary logic until it was toggled off, and the optional Trimmer accessory occasionally hung up on rocks. As with all X3 mowers it is two-wheel drive, so the 50% slope rating assumes straight up-and-down runs, and there is no onboard rain sensor. Compared with a Husqvarna Automower 450X at roughly $4,000 installed, the X350 is a DIY afternoon and about a third cheaper; compared with the Mammotion Luba 2 AWD 5000 it gives up AWD hill-climbing for faster, straighter cutting. Best for 1 to 1.5 acres of mostly open, gently rolling lawn.

Best for Lawns of 1 to 1.5 acres with scattered trees and only gentle grades, for owners who want DIY setup instead of a dealer install.

The X4 is the mower Segway built to answer the Luba: four hub motors with dual suspension, an 84% (40 degree) slope rating, and a 17 in dual-disc deck driven by two 180 W motors, all on a 64 lb body that can step over 2.8 in obstacles. It comes as the X430 (1 acre, 10.2Ah, $2,499) and the X450 (1.5 acres, 12.8Ah, $2,999), both charging in about 90 minutes at 224 W. The big change from the X3 series is that positioning uses tri-frequency Network RTK delivered over the built-in 4G, so most yards need no antenna at all, and the front wheels steer independently so it turns like a car instead of pivoting and scuffing turf. How-To Geek gave it an Editor's Choice after a season: auto mapping finished a backyard in ten minutes, EdgeSense cut within 2 in of fences, and it ran quietly at night, but the dock still had to be moved twice to find sky, the first pass looked choppy until a second run, and it drove up onto a raised patio and scuffed the coating. 9to5Toys found it handled soggy, uneven ground but chewed turf when wet and missed dog waste hidden in tall grass. Against the Mammotion Luba 3 AWD 3000 at $2,109 the X430 costs more and rates 4% less slope, but cuts an inch wider, goes down to 0.75 in for warm-season turf, and its Ackermann steering is gentler on grass.

Best for Hilly, rutted or rough-terrain lawns of 1 to 1.5 acres where an AWD mower with a wide deck beats the two-wheel-drive X3.

The X330 is the X3 model most people should look at: a one-acre rating, 8Ah battery for about 160 minutes of mowing with a 65 minute recharge, and it sits at $2,299 on Segway's site after a $500 cut from launch pricing. Like the rest of the X3 line it runs EFLS 3.0 - RTK fused with three cameras doing visual SLAM - so it holds position under tree canopy where the older H series and most budget RTK mowers lose lock, and its 300-degree camera plus ToF array recognizes 200+ obstacles with night vision. It mows fast (about 3.3 ft/s) in tidy parallel stripes, cuts 2 to 4 inches, runs at 60 dB, and includes two years of 4G with GPS tracking before the roughly $33 a year Connect+ renewal. Pro Tool Reviews and Robot Review Desk both call the X3 the most polished wire-free mower for flat-to-moderate suburban lots. Where it falls short: two-wheel drive makes the 50% slope rating shaky on side-hills, there is no physical rain sensor (it relies on forecasts), the centered 9.3 in disc leaves a few inches uncut along walls unless you buy the Trimmer accessory, and 43.7 lb is a lot to lift over a curb. Against the Mammotion Luba 2 AWD 3000, the X330 is quicker and gentler on turf but the Luba climbs 80% grades. For a one-acre yard with trees and gentle slopes, this is the sweet spot of the range.

Best for One-acre suburban lawns with tree cover and gentle slopes where fast, precise striping matters more than hill-climbing.

The H3000N-VF is the big-lawn version of Segway's original H series, rated for 0.74 acre with the same 8.3 in cut, 54 dB hub motors and 38.6 lb chassis as the H1500N but a larger battery (about four hours of mowing, five hours to recharge) and three years of 4G service bundled instead of one. It is being cleared out as the H2 and X3 lines take over, so it has sold on Amazon for $1,199 to $1,299 - sometimes less than the smaller H1500N - and Home Depot still lists it while Segway's own store shows it sold out at $2,599. Amazon owners say setup is easy and the finish looks great, and one reports about a third of an acre per charge. The gripes are familiar H1 issues: wheels that lack grip on damp slopes despite the 45% rating, boundary edits that are fiddly, some random-looking path choices, and RTK-only EFLS 1.0 positioning that struggles under tree canopy because the VisionFence camera only avoids obstacles. The 1.2 to 2.4 inch cutting height range is the real limiter for cool-season grasses. Against the Mammotion Luba 2 AWD 3000 at a similar clearance price you give up all-wheel drive and a 4 inch max cut but gain quieter running and a 4-year warranty. Best for a flat, open three-quarter acre of short-cut warm-season grass.

Best for Flat, open lawns up to three-quarters of an acre kept at golf-course height, for buyers who find it near $1,200.

The X315 is the entry to Segway's X3 line: the same 43 lb chassis, 9.3 in cutting deck, 2 to 4 inch height range and EFLS 3.0 positioning as the $4,499 X390, just with a 6Ah battery good for about two hours and a half-acre rating. EFLS 3.0 fuses RTK with three cameras doing visual SLAM and odometry, which is why testers at Notebookcheck and TechRadar found it kept mowing straight under trees where RTK-only mowers stall. Obstacle avoidance uses a 300-degree camera array with a ToF sensor and recognizes 200+ objects including pets, with night vision so it can run after dark at 60 dB. Setup is about 30 minutes and truly wire-free, though you still mount an RTK antenna. Segway has pulled it from its own store (listed at $1,999 but unavailable) while Home Depot, Acme Tools and Abt still sell it, and it is the only X3 that does not get multiple years of 4G included - one year, then about $33 a year. Reviewers' knocks: it is two-wheel drive so the 50% slope rating is optimistic on side-hills, there is no onboard rain sensor (it relies on forecasts), the single 9.3 in disc leaves about 3.5 in uncut at edges without the optional Trimmer accessory, and standby power draw is high. Versus the Mammotion Yuka at $1,399 the X315 costs more but is faster and better under trees; if you are near 0.5 acre, the X330 is often only $300 more.

Best for Half-acre suburban yards with tree cover where you want X3 navigation and app polish at the lowest buy-in.

The H1500N-VF is Segway's first-generation premium mower, now on clearance as the H2 series replaces it, and the pricing is chaotic: Segway's store lists it sold out at $2,199, Amazon has bounced between $999 and $1,599, and Home Depot still carries it. What you get is a heavier 38 lb machine with quiet in-wheel hub motors (54 dB, the quietest Navimow), a battery that runs about four hours, built-in 4G with a year of service, and a real rain sensor. Navigation is EFLS 1.0 - RTK only - so it needs a clear sky over the antenna; the plug-in VisionFence camera pod on the back handles obstacles but does not help positioning, and Amazon owners report the map drifting by a few feet on tough sites and the mower crossing mapped boundaries. The dealbreaker for many US lawns is cutting height: 1.2 to 2.4 inches is a golf-course range, far too low for fescue or St. Augustine that wants 3 inches or more. The 45% slope rating beats the i series though, and owners praise how it handles ditches and uneven ground once mapped. Buy it only if your lawn is short-cut grass on a mostly open lot and you find one near $1,000; otherwise the newer X330 or H220 gets you 2 to 4 inch cutting and vision-fused positioning for not much more.

Best for Open, mostly treeless lots up to a third of an acre with short-cut grass, bought at clearance pricing.

The i215 is Segway's first LiDAR mower and the first Navimow with no satellite dependence at all: a solid-state LiDAR unit scanning about 200,000 points a second to 230 ft, fused with a front camera, builds the map itself and holds position under tree canopy and beside the house where the RTK i-series lost lock. It is a bigger machine than the i2 AWD, with an 8.6 in six-blade disc, motorized 2 to 4 in height, a 7.65Ah battery good for about 160 minutes (130 minute recharge), 32 lb, and a 0.37 acre rating, at $1,599 list ($1,399 on sale this summer). PCWorld called it the robot mower that makes setup simple: two firmware updates and a joystick nudge onto the grass, then it mapped a 7,645 sq ft yard on its own and cut cleanly at 3.2 in. The same tester had to rescue it twice after it slipped off a narrow grass strip, because there is no cliff sensor and edges depend entirely on the map. AndroidGuys got a consistent finish across an obstacle-heavy yard but noted the rear-wheel drive gives up on side slopes, ruts and wet patches long before the sensors do, and that 4,570 sq ft per cycle means a full 0.37 acre runs over a day or two. Set against the X315 at $1,999, the i215 is cheaper, needs no antenna, but is two-wheel drive with a narrower deck and a smaller rating; against the Mammotion Luba 3 AWD 1500 at $2,399 it trades AWD and 80% slopes for $800 and a simpler, antenna-free install.

Best for Tree-shaded, obstacle-filled lawns up to a third of an acre with only gentle slopes, where RTK mowers lose their fix.

The i110N is the same 7.1 in body as the i105N with double the battery (5.1Ah, about 120 minutes per charge) so it can cover a quarter acre, and it won Tom's Guide's Editor's Choice for cut consistency at a price that has slid from $1,299 at launch to a $929 list and frequent sub-$800 sales. It uses Segway's EFLS 2.0 RTK plus a front VisionFence camera, so when the satellite fix wobbles under trees it can hold the boundary visually for a while instead of wandering off. Reviewers consistently praise the straight, overlapping stripes with no missed patches and the near-silent 58 dB operation that makes night mowing realistic. The complaints are the flip side of the budget price: it is slow (Tom's Guide clocked roughly three times the time of push mowing), the 30% slope rating and front-wheel drive mean it spins out on real hills, PCWorld's unit repeatedly drove off curbs because there is no drop-off detection, and GPS anti-theft needs the $120 Access+ 4G module. Segway has pulled it from its own store in favor of the i210 AWD, but Home Depot still stocks it. For a flat quarter-acre suburban lot it remains one of the cheapest dependable wire-free options; if your yard has slopes or a parking strip, look at the i210 AWD or a Luba Mini instead.

Best for Flat quarter-acre suburban yards where you want a quiet, accurate wire-free mower on a budget and can live with slow cycles.

The i2 AWD replaces the i105N and i110N with the same 7.1 in single-disc body but three fixes for the old model's main complaints: a third, on-demand drive motor on the front zero-turn wheel with knobby off-road tires, a 4G module built in instead of the $120 Access+ add-on, and Network RTK that removes the antenna from setup where coverage exists. Slope rating rises from 30% to 45%, and Segway says the rear motor only engages when traction is needed, which stretches runtime by up to 30%. The i206 AWD ($999) carries a 2.55Ah pack for about an hour of mowing and a 0.15 acre rating; the i210 AWD ($1,299) doubles that to 5.1Ah, roughly two hours, and a quarter acre, and both recharge in about the same time they run. The cutting hardware is unchanged: 2 to 3.6 in height on a manual knob, a narrow deck, and no edge mode. Mowing Magic found the zero-turn wheel stopped the turf scuffing that plagued the i1 and rated the 59 dB noise as conversation-level, but confirmed the manual height knob and the uncut wall strip. Compared with the leftover i110N at $929 you pay a little more for real traction, built-in 4G and antenna-free setup; compared with the i215 LiDAR at $1,599 you give up LiDAR positioning under heavy tree canopy and the wider 8.6 in deck.

Best for Small suburban yards up to a quarter acre with a few slopes or muddy patches, for buyers who want antenna-free setup under $1,300.

The i105N is the mower that made wire-free RTK cheap. Segway cut it from $999 to $799 in 2026 and it regularly dips to $669-699, which puts it in Worx Landroid Vision territory while still using a proper RTK antenna for centimeter-level positioning. It is small - 7.1 in cutting width, 24 lb, a 2.55Ah battery good for about an hour - so the rated 1/8 acre is honest; Amazon owners with a typical city lot say a full cut takes around 2.5 hours across two or three charge cycles. Setup is genuinely DIY: mount the antenna somewhere with open sky, drive the mower around the perimeter with your phone, and let AI Assist Mapping snap to the lawn edges. Owners like the quiet 58 dB motor, the straight-line stripes, and that it pays for itself in a season versus a lawn service. The knocks are consistent too: getting stuck on flat ground and in dips, mapping frustration when trees hang over the antenna, a manual cutting-height dial, and a few units dying after a few months with slow email-only support. The 30% slope limit and front-wheel drive rule out anything hilly. Compared with the Mammotion Yuka Mini, the i105N is cheaper and simpler but has no vision-only mode when RTK is hopeless; step up to the i110N if you have more than about 5,000 sq ft.

Best for Flat city lots under 5,500 sq ft where a quiet, cheap wire-free mower matters more than hill-climbing or speed.
