Lymow One Plus Robot Lawn Mower Review

The reason to choose this mower over a wheeled robot is under the body. Rubber caterpillar tracks drive all four corners, rated to 45° slopes and able to cross obstacles up to 2.8 in tall. On a yard with a bank, a ditch or a rutted back lot, that is the difference between a robot that finishes the job and one that beaches itself.

The cutting hardware is a real mower's, not a trimmer's. Two 16 in SK5 tool-steel blades spin at 3,000 to 6,000 RPM, powered by a 680 W rated motor that peaks at 1,785 W, with a Cyclone Airflow deck lifting grass into the blades. Fixed rotary blades slice tall, thick grass cleanly, where the pivoting razor blades common in the category tend to push it over. Cut height runs from 1.2 to 4 in and adjusts electrically from the app, so a seasonal change takes a tap instead of a wrench.

Navigation is wire-free. RTK satellite positioning paired with vision (RTK-VSLAM) maps the lawn without a boundary wire, and heated camera lenses keep the visual side working under tree canopy and in low light.

The body is an A380 die-cast aluminum frame rated IPX6 for rain. Privacy Mode keeps all data on the machine, and the mower runs normally offline; Wi-Fi is only needed for over-the-air updates.

Buyers on Amazon most often praise ease of use, performance, build quality, appearance, handling and the time it saves, and one customer notes it handles steep slopes without slipping or leaving ruts. The large majority of ratings are four or five stars, and complaints are rare.

A dual-blade deck on a tracked body cannot reach the last few inches along a fence or a flower bed. Expect an uncut strip at the borders and plan on a string trimmer for the perimeter.

The cut height bottoms out at 1.2 in. Bermuda lawns are usually kept shorter than that, so this is a poor fit for Bermuda.

Siting the RTK antenna, docking the mower on level ground and mapping the lawn take time. Blades and tracks are not covered by the 3-year warranty.

A rotary-blade machine is louder than a razor-blade robot. Updates need Wi-Fi or a hotspot. Support is direct from the maker by email.

Going wire-free does not mean going setup-free. The mower depends on an RTK base station with a clear view of the sky, and where you put that antenna decides how well the whole system works.

Mapping is done once and stored, with room for up to 15 acres of map and 80 zones.

Once the map is in, the mower runs offline as normal. Wi-Fi or a hotspot is only needed when an over-the-air update arrives.

The dual steel blades and the Cyclone Airflow deck are built for grass that stands tall. St. Augustine, Bahia and tall fescue all sit comfortably inside the 1.2 to 4 in range, and the 1,785 W peak power lets the blades push through thick growth instead of stalling.

The blade design matters more than the number. Most robots in this category use pivoting razor blades that swing away from anything tough; this mower uses fixed rotary blades that cut the way a walk-behind mower does.

Bermuda kept short is the exception. Its usual cut height sits below the machine's 1.2 in floor, so a Bermuda lawn will look shaggy no matter what you set.

The tracked AWD system is the whole point of this mower. Tracks spread the machine's weight over a wide footprint, which gives it grip on loose soil and wet grass that wheels struggle to match, and the 45° rating and 2.8 in obstacle crossing cover most of what a rough yard throws at a mower.

RTK-VSLAM combines satellite positioning with camera vision, and the heated lenses keep the visual side working under canopy and after dusk. Up to 80 zones can be mapped, each with its own settings from the app, and Bluetooth, Wi-Fi and 4G keep the mower connected, with the first year of SIM service included.

Privacy Mode keeps the data local, so nothing goes to the cloud while the mower works.

A rotary-blade robot is louder than a razor-blade one, and this mower is no exception.
