Lymow One Plus 5A

What it is

The Lymow One Plus is a wire-free robot mower that runs on crawler tracks instead of wheels and cuts with two rotary mulching blades. It navigates with RTK satellite positioning plus VSLAM camera mapping. This listing is locked to the US 5A version: variant 47332598710507, SKU LM1PLUSUS5A, titled “5A | 1.1 Acres/Day”. The only other US variant is the 10A version (variant 47332598743275, SKU LM1PLUSUS10A, $3,199). Both versions share one spec table and the same 15 Ah battery. The table only separates them on charging: the 5A charges from 10% to 90% in 150 minutes at 39 V, and the 10A does it in 90 minutes at 40.5 V. The variant names put the 5A at 1.1 acres per day and the 10A at 1.73 acres per day. The One Plus is not the earlier Lymow One, and Lymow says the two models’ blades and batteries are not interchangeable.

Who it’s for

The One Plus suits a lawn with steep banks, tree roots, branches or gravel edges where a wheeled robot would slip or get stuck. The tracks are rated for 45° (100%) and for crossing 2.8-inch obstacles. It also fits yards where the grass gets tall or thick, or where you want fallen leaves mulched in place. Lymow pitches the dual rotary blades at exactly that.

Before you buy, plan where the RTK reference station goes. It is included, but the mower barely works without it: Lymow lists only 0.025–0.037 acre, or about 10 minutes, of mowing without RTK. The box includes the station, a radio antenna, two mounting poles, a wall-mount bracket, an RTK ground stake, expansion bolts, the RTK power adaptor and two 5 m RTK extension cables, so the station can go on a pole in the ground or on a wall, near a power point. The charging station also needs power; it comes with an adaptor, a 10 m extension cable and four ground stakes. There is no boundary wire. You map the lawn with your phone and draw virtual boundaries in the app.

Lymow does not publish a maximum lawn size. The area figure for this SKU is 1.1 acres per day in the variant name, backed by 0.57 acre per charge and 0.23 acre per hour in the spec table. coverageAcres uses that 1.1 figure. Treat it as an upper daily figure, not a lawn-size rating: Lymow footnotes its 1.73-acre daily figure as a lab maximum on flat ground with continuous mowing. The 15-acre figure is map storage, not coverage. If the lawn is near or above an acre and you want it cut in one day, look at the 10A version (1.73 acres per day, $200 more). Skip the One Plus if the yard is small and flat and you don’t want to site an RTK station and move a 78.5 lb machine around.

Standout details

• Drive and slope: heavy-duty tracks with hub motors, rated for 45° (100%) slopes and 2.8-inch obstacles. Lymow names tree roots, branches, steep slopes and gravel as target terrain.
• Cutting: two rotary blades made from SK5 tool steel (50 HRC), a 16-inch cut and a floating deck. Height adjusts from 1.2 to 4.0 inches, and you can set a different height for each zone. Clippings go out a single side discharge. The page says the blades mulch fallen leaves, and that the deck lifts automatically for cleaning.
• Navigation: RTK + VSLAM, 3,200 ft RTK radius, 15 acres of map storage, up to 80 zones, plus AI vision and ultrasonic obstacle avoidance. The mower returns to charge when the battery is low or it detects rain, then resumes where it stopped.
• Battery and charging: a 15 Ah LiFePO₄ pack rated for 2,000 cycles and up to 3 hours of runtime per charge. The 5A version recharges from 10% to 90% in 150 minutes.
• Build: an A380 aluminum frame, IPX6, and 78.5 lb (±1 lb).
• Security and connectivity: geo-fence alerts, a device lock and live GPS tracking. Connectivity is Bluetooth, Wi-Fi and 4G. The same store sells Lymow 4G Service plans ($22.90 for 6 months, $34.90 for 12 months), and the product page does not say whether any data period is included.
• In the box: the mower, charging station, charging station adaptor, 10 m charging station extension cable, 4 ground stakes, RTK reference station, radio antenna, 2 mounting poles, wall-mount bracket, RTK ground stake, 4 expansion bolts, RTK power adaptor, 2 × 5 m RTK extension cables, user manual and quick start guide.
• Purchase terms on this date: free shipping; estimated US ship time 1–3 business days; 3-year limited warranty; 30-day returns. US sales tax is added at checkout, according to Lymow’s FAQ.

Page conflicts (the spec table is used here):

• Daily coverage: the variant names give 1.1 acres per day for the 5A and 1.73 for the 10A. The spec table lists one “Maximum Coverage Per Day 1.73 Acres” figure without naming a version, and the overview says “Mows up to 1.73 acres with fast 10A charging”. The 1.73 figure is treated as the 10A rating, and this listing uses the 5A’s 1.1.
• Blade speed: the overview says the blades spin “at 6000 RPM”. The spec table gives 3,000–6,000 RPM, marked as a lab figure.
• Motor power: the product page gives a 1,785 W peak and 680 W rated blade motor. The store-level description in Lymow’s Shopify data says “1200W motors”. The product page figures are used.
• Zones: “up to 80 zones” in the spec table and most of the copy, but “80+ Zones” on one feature tile.
• Noise: no noise figure is published, so noiseDb is omitted.

Honest verdict

For $2,999 (full price on 14 Oct 2026; the earlier $2,499 sale ended), the One Plus 5A offers a steep, rough or overgrown yard a tracked chassis rated for 100% (45°) slopes, twin rotary blades and a 16-inch cut, with no boundary wire. What you give up is simplicity. You have to site and power the included RTK reference station, the machine weighs 78.5 lb, and Lymow rates it by acres per day (1.1 on the 5A) rather than giving a maximum lawn size. Buy the 5A if your lawn is well under that daily figure. For about an acre or more a day, the One Plus 10A (lymow-one-plus-10a) is $3,199, $200 more, rated for 1.73 acres per day, and recharges in 90 minutes instead of 150.
