Overview
The RockMow X120H LiDAR ($3,199) is the top version of the Roborock RockMow X1. It is rated for lawns up to 2,000 m² and slopes up to 80%. Navigation: 360° 3D LiDAR + dual cameras, no RTK.
LiDAR version of the RockMow AWD: no RTK antenna, 80% slopes and strong performance under trees.
On paper it suits typical suburban gardens — the manufacturer rates it for up to 2,000 m². With an 80% slope rating and all-wheel drive it is one of the better climbers in our catalog, built for hillside lawns and rough ground. As always, treat the area figure as a best case: buy with a 30–50% buffer if your lawn has slopes, trees or narrow passages.
Its LiDAR sensor scans the garden in 3D and lets the mower localise itself against that map, so it keeps working under trees, next to house walls and at dusk — places where satellite-only mowers often lose their position. Satellite RTK positioning gives centimetre-level accuracy on open lawns, which means virtual boundaries drawn in the app, several zones and neat parallel stripes instead of random mowing.
It mows with a 24 cm cutting width and a cutting height of 41–89 mm. Cutting system: 1 disc, 6 blades. Edge cutting: Optional, 1.2 in from edge. Power comes from a 6 Ah battery — 110 min runtime, 50 min charge. It weighs about 21.7 kg. Connectivity: Wi-Fi, Bluetooth, built-in 4G (3 years included).
The RockMow X1 family also includes the RockMow X115H, RockMow X130H; the versions differ mainly in rated area, battery and price, so pick the smallest one that covers your lawn with a margin.
Price: $3,199 (US list price). Prices vary by market and retailer — check current offers before buying.
