Our verdict
Should you buy the Lymow One Plus?
A desk-based verdict from the manufacturer’s specifications, manuals and UK warranty terms.
Pros
- Tracks rather than wheels, with a 100% (45°) slope rating
- Wide 406 mm cut with a height range from 30 mm to 102 mm
- Up to 80 zones, with 4G, Wi-Fi and Bluetooth
- RTK station and mounting kit included
- Sold through a UK store in pounds, with a three-year warranty
Cons
- Very heavy at 35.6 kg, so moving it between lawns is hard work
- Without an RTK fix it can only cover a small patch
- The quoted areas are theoretical daily maximums, not recommended lawn sizes
- Warranty excludes tracks and blades, and only applies in the country of purchase
- No published noise level, and app features aren't fully documented
Who it’s for
- Large lawns and paddock-like areas of an acre or more
- Very steep banks that wheeled mowers can't manage
- Longer, rougher grass that suits a tall 102 mm maximum height
Who should avoid it
- Your garden is small, fussy or full of narrow gaps: it's a big, 36 kg machine
- Your lawn is heavily shaded: it depends on RTK and covers very little without it
- You want to know how loud it is: Lymow doesn't publish a noise figure

Claims vs reality
Where the brand’s marketing and its own small print don’t agree.
They sayThe One Plus is listed as covering up to 1.1 or 1.73 acres, depending on version.
In practiceThose are Lymow's per-day theoretical maximums, set by charging speed, not a recommended lawn size. Compare with care against rivals, whose ratings usually describe the lawn size they're designed for. Source
They sayLymow describes RTK plus vision navigation.
In practiceThe mower relies on RTK. Lymow says that without an RTK fix it can only mow about 100–150 m², so it isn't a fallback for shaded gardens. Source
Which version do you need?
The mower is identical in both versions; only the charging adapter differs. The 10A adapter recharges faster, which is why Lymow gives it a higher daily coverage figure (1.73 acres a day against 1.1). If your lawn is near the top of the range or you want it mown quickly, the 10A is worth the extra; otherwise the 5A does the same job more slowly.
How it navigates and sets up
The One Plus positions itself with RTK, using a reference station supplied in the box, and adds camera-based mapping (VSLAM), an AI camera and five ultrasonic sensors for obstacles. Lymow is clear that RTK does the heavy lifting: without a fix it can only manage a small patch. The station needs a spot with a clear view of the sky, on the supplied pole or wall kit. There's no wire to lay, and Lymow treats it as a self-install job; see our installation guide.
It runs on tracks rather than wheels, and Lymow rates it for 100% slopes and obstacles up to 71 mm, the latter marked as a lab figure. At 35.6 kg it's more than twice the weight of most robot mowers, so consider whether you'll need to lift it between lawns.
Cutting
The deck is 406 mm wide with 2 rotary mulching blades, rather than the small pivoting razor blades most robot mowers use; Lymow sells alternative blade types as options. The height range runs from 30 mm to 102 mm, taller than most rivals, which suits rougher grass. Lymow doesn't publish a noise figure for the One Plus; the earlier Lymow One was quoted at 68 dB(A), which is loud for this type of mower.
App, connectivity and security
The One Plus connects over 4G, Wi-Fi and Bluetooth and supports up to 80 zones. Lymow sells 4G renewals tied to each mower's SIM, but doesn't state how many months are included or whether mowing stops without a plan. It also hasn't documented the app name, no-go zones or anti-theft features on its UK page. The mower returns to charge when it detects rain.
Running costs, warranty and support
Lymow sells the One Plus through its own UK store in pounds, from £2,799. The warranty is 3 years, excluding tracks and blades, and only applies in the country of purchase. There's no dealer network, and Lymow's support runs through its customer-service email and help centre. Budget for blades, tracks and optional 4G renewals; the running-costs calculator can help.

Lymow One Plus questions and answers
What's the difference between the Lymow One Plus 5A and 10A?
Only the charger. The Lymow One Plus is the same mower in both versions; the 5A and 10A refer to the charging station adapter. Lymow says the 10A adapter takes the battery from 10% to 90% in about 90 minutes, against about 150 minutes with the 5A.
Faster charging means more mowing time in a day, which is why Lymow quotes 1.1 acres a day for the 5A and 1.73 acres for the 10A. Those are daily theoretical maximums, not recommended lawn sizes, so don't compare them directly with the area ratings other brands give. The 10A makes most sense if your plot is large or you want it finished quickly; for a smaller area the 5A does the same work more slowly. The two sell for £2,799–£2,999, and Lymow also sells both adapters separately.
Can the Lymow One Plus cut long, rough grass like a paddock?
It's designed with rougher ground in mind more than most robot mowers, but Lymow doesn't say how long grass can be before it struggles. The Lymow One Plus uses 2 rotary mulching blades across a 406 mm deck, rather than the small pivoting razor blades on a disc that most robot mowers use. Lymow quotes a blade speed of 3,000 to 6,000 rpm and offers alternative blade types, including swing blades, as options.
The height range is also generous, from 30 mm up to 102 mm, which lets you keep a longer, meadow-style finish. It runs on tracks, is rated for 100% slopes, and can climb obstacles up to 71 mm according to Lymow's lab figure.
Like any robot mower, it works best on grass it keeps short with frequent runs. If a paddock has become overgrown, cut it down first with a conventional mower or brush cutter, then set the robot's height and let it maintain it. Rough fields bring other hazards: stones, molehills and fallen branches can damage blades, and Lymow's warranty excludes blades and tracks. Remember too that the mower depends on RTK positioning; Lymow says it can cover only about 100 to 150 m² without a fix, so a paddock surrounded by tall trees may be a problem. Our blades guide covers blade types and replacement.
More questions
Frequently asked questions
Why does the Lymow One Plus use tracks?
Tracks spread the weight and grip better than wheels on steep or soft ground. Lymow rates the One Plus for a 45° (100%) slope, well above most wheeled robot mowers. Wet grass still reduces grip, so leave some margin.
Does it need an RTK base station?
Yes. An RTK reference station, antenna and mounting kit are in the box, and it needs a clear view of the sky. Without RTK, Lymow says it can only cover a very small area.
Is there a 4G subscription?
Lymow sells 4G renewals, but doesn't say whether mowing works without an active plan. It also connects over Wi-Fi and Bluetooth.
