Lymow One Plus

The X7 Plus is the long-range version of Sunseeker's AWD X7: same 14 in dual-disc deck, same 70% slope rating, same RTK-plus-camera AONavi navigation, but a higher-capacity battery that lets it schedule 1.5 acres instead of 0.75. List is $2,999.99 at Sunseeker (frequently sold out) and dealers such as Robotic Mower Services sell a Gen 2 at $2,799.99; the Amazon listing has been unavailable for a while. That undercuts a Mammotion Luba 2 AWD 5000 by several hundred dollars for similar coverage and traction. In practice it is a systematic-row mower with 100 zones, virtual walls and no-go areas, edge trimming to about 1.2 in, a rain sensor, and 4G tracking with a geofence lockout. Reviewers who ran the standard X7 praised the AWD on lumpy, sloped ground and the way the twin cameras learn the yard over a few passes, and criticized the app (a single joystick for mapping, thin documentation, schedules that are easier to leave in auto mode). Obstacle avoidance is good for people, pets and toys, but small low objects like a softball can be run over, and like every RTK mower the reference station needs open sky. At 60 dB it is quiet for a 31 lb machine with two spinning discs. Best for hilly 1 to 1.5 acre properties where AWD matters and the buyer is fine trading Mammotion's app polish for a lower price.

Best for Large, hilly properties up to 1.5 acres where all-wheel traction and wire-free RTK mapping matter more than app polish.

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 4WD is the same Vision Cloud brain - cloud-delivered RTK with no antenna and no subscription, stereo cameras running V-SLAM, self-mapping Vision AI, Cut-to-Zero offset blade, electric 1.57 to 3.54 in height adjustment - moved onto a four-wheel-drive chassis with front-wheel steering and a body that flexes to keep all four tires on uneven ground. Worx rates it for 84% (40 degree) slopes against 30% for the 2WD, which matters because reviewers of the 2WD watched its drive wheels spin and dig on the edges of a 20 to 30 degree lawn. Three tiers on one 8.7 in deck: WR341 (1/4 acre, 4Ah, $1,999.99), WR342 (1/2 acre, 5Ah, $2,299.99) and WR344 (1 acre, 5A 60 minute charger, built-in 4G, GPS module and FiatLux night light, $2,999.99); the WR344 has sold for $2,399.99 on Amazon. It weighs 37 to 40 lb with the battery, several pounds more than the 2WD, and the 20V Power Share pack still swaps into any Worx tool. What it lacks in September 2026 is a track record: it shipped this spring and there are no substantive hands-on US tests yet, so the slope number is Worx's claim, and a 1 acre rating on a 5Ah pack implies long daily schedules. Against the Mammotion Luba 3 AWD, which pairs an 80% rating with 360-degree LiDAR from $2,109 on sale for its 3000 tier, the Worx costs about the same for less coverage but carries a big-box warranty and battery ecosystem.

Best for Steep, uneven or thick-grass lawns up to an acre, for buyers who want wire-free RTK from a big-box brand without mounting an antenna.

The Luba 2 AWD X is the mower that made Mammotion a household name in the US, and in fall 2026 it is a clearance buy: Mammotion's own store shows every trim out of stock with a banner pointing at the Luba 3, but Home Depot and Best Buy still have units, with the 3000X down from $2,599 to about $1,999. What you get is the same all-wheel-drive body that climbs 80 percent grades, a 15.7 inch dual-disc deck that clears a big yard fast, and a 2025 X refresh that added the UltraSense AI camera so it keeps its bearings when the RTK station loses sky. The catch is that RTK station: it must be mounted high with an open view, and most owner complaints trace back to a poorly placed antenna. The X version cuts 1.0 to 2.7 inches, so northern cool-season lawns should look for the HX (2.2 to 4.0 inches) instead. Versus the newer Luba 3 you give up LiDAR and free NetRTK, which matters if your lawn is ringed by trees; versus a Segway Navimow X3 you gain real AWD and a wider deck. Best for hilly half-acre to 2.5 acre properties with decent sky, bought on discount.

Best for Big, hilly lawns with open sky where a discounted last-generation AWD mower beats paying full price for the Luba 3.
