Lymow One Plus (5A / 10A) video review

The Lymow One Plus is a tracked, 16”-deck robot mower built for terrain that defeats wheels: steep banks, rough pasture-like grass and overgrown rural lots. On those properties it has few real competitors. On a tidy, flat suburban lawn, its weight, noise, RTK base and manual mapping are costs you don’t need to pay. It sits in the premium price tier (October 2026).

Who the Lymow One Plus is for (and who should skip it)

It’s for owners of hilly, bumpy or rough acreage who would otherwise be on a riding mower or a string trimmer. It also suits people who let grass get long between cuts and want something with real rotary blades instead of razor discs.

Skip it if:

• Your lawn is flat and well kept. A wheeled AWD robot like the Navimow X4 is quieter, lighter and easier to set up.
• You can’t place an antenna with a clear sky view. It needs its RTK base station, and heavy tree cover will hurt accuracy.
• You expect to replace your mower entirely. Even Tom’s Guide’s broadly positive reviewer said she wasn’t ready to retire her riding mower.

Navigation and setup

The One Plus combines RTK with VSLAM, AI vision and ultrasonic sensors. Unlike the antenna-free network-RTK mowers, it ships with its own RTK reference station, cabled to the dock, which needs an open view of the sky. Tom’s Guide’s reviewer moved the dock and antenna around before settling on the corner of her deck. TechAeris called antenna placement critical. Our navigation explainer covers why RTK cares so much about sky view.

Mapping is manual. You drive the mower around the perimeter like a remote-control car, using the app or the onboard screen, then mark no-go zones. Tom’s Guide spent about 20 to 30 minutes doing this for a roughly 6,800 sq ft yard with a shed, playset and trampoline, and said she actually enjoyed it. Budget 30 to 45 minutes for a larger or more complex property. The app supports up to 80 zones with their own heights and schedules, and the mower stuck to its boundaries and no-go areas in Tom’s Guide’s testing. Our setup guide has tips for planning zones and dock channels.

Mowing performance, slopes and terrain

The tracks are the reason this machine exists. Lymow rates the One Plus for 45°, which is a 100% grade. That’s a marketing ceiling measured on dry, short grass, not a safe everyday target. TechAeris reported the tracks provide “extraordinary traction, allowing the mower to climb steep 45-degree slopes and roll right over obstacles.” For context, the best wheeled robots are rated around 80–84%. See our slope limits explainer for how much margin to leave.

Cutting uses Lymow’s LyCut 2.0 system: steel rotary blades at up to 6,000 rpm instead of the small pivoting razors most robots use. TechAeris said it “actually lifts, cuts, and mulches thick grass and leaves like your push mower.” Tom’s Guide was more mixed. Starting on an unmowed spring lawn at a 4” height, the mower crossed thick patches easily but flattened some tufts and dandelion stems instead of cutting them, leaving patches behind. Her lawn still “looked professionally mowed, with even stripes,” but she concluded she’d need a manual mow every few weeks.

TechAeris also noted the obstacle sensor occasionally mistook sudden dips in the ground for obstacles at higher speeds.

Coverage, cutting and runtime

The 16” deck is one of the widest in this class, and the 1.2” to 4” cutting range covers tall fescue. Lymow quotes 1.1 acres per day for the 5A and 1.73 acres for the 10A, but those are daily figures across multiple charges. Per charge, figure on about 0.57 acre. TechAeris put realistic daily capacity at roughly half an acre. In Tom’s Guide’s 6,800 sq ft yard, one session took 104 minutes and used 124% of the battery, so it docked once mid-job.

The battery is a 15 Ah LiFePO4 pack, a chemistry known for long cycle life. TechAeris cites a 2,000-cycle rating. Recharging takes about 90 to 120 minutes with the 10A charger, or about 180 minutes with the 5A charger, per the two reviews.

App, connectivity and anti-theft

The app shows live position and progress, supports scheduling, cutting height, blade speed and mowing speed, and lets you back up and restore maps. Anti-theft features include geofence alerts, a device lock and live GPS tracking. Tom’s Guide’s spec box lists Bluetooth, Wi-Fi and 4G. We haven’t been able to confirm the radio specs from Lymow directly, so check cellular support on the current listing if remote tracking matters to you. Our theft protection guide has more.

Ownership notes

• Weight. About 78 lbs. Tom’s Guide said the box needed two people. Plan winter storage accordingly.
• Noise. Both reviews describe it as noticeably louder than typical robots, though quieter than gas. Lymow doesn’t publish a dB figure.
• Build. An aluminum frame and IPX6 rating suit a machine that lives outdoors on rough ground.
• Install hassles. TechAeris had trouble driving the dock’s ground pegs into rocky soil.
• Firmware. Expect updates early on. TechAeris noted a learning curve that improved with software updates.
• Buying. Lymow has sold mainly direct. Amazon availability and pricing have varied, so compare before buying.

How it compares

On a normal sloped lawn, the Segway Navimow X4 is the better buy at a similar price: antenna-free, quieter, lighter, with a wider deck and an 84% rating. The Mammotion LUBA 3 AWD adds LiDAR for yards with trees. The Husqvarna Automower 435 iQ AWD is the dealer-backed steep-yard option, at about twice the price with a much narrower deck. The Lymow wins only when the ground itself is the problem.

Bottom line

The Lymow One Plus is a specialist. If your property has steep banks, rough grass or terrain that strands wheeled robots, its tracks and real rotary blades make it one of the few robots worth trying, and TechAeris gave it a 9.7/10 Editor’s Choice for exactly that use. If your lawn is a manicured suburban rectangle, it’s the wrong tool. Both the 5A and 10A versions sit in the premium tier, so check today’s price.
