Segway Navimow X330

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.

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.

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.

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.

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.

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.
