Every wire-free and RTK robot mower, compared by lawn size, slope, navigation, and price, each spec linked to its source.
Best for each lawn pinned up top, each with the one number that decides it. How we pick
Or set your lawn
For most lawns, the MOVA LiDAX Ultra 2000 is the best all-round pick: it covers up to 2,000 m² (0.49 acre) from $1,099, with LiDAR obstacle avoidance that holds position under tree cover ($0.55 / m² of coverage, among the best value that also avoids obstacles).
For large lawns, the Segway Navimow X390 covers the most ground of any shipping model, rated to 10,118 m² (2.5 acres), from $4,499.
For a small lawn, the Sunseeker V3 is the best-value pick at $599.99: the cheapest wire-free mower that comfortably covers a compact yard (up to 600 m² (0.15 acre)).
For steep or terraced ground, the Dreame A3 AWD clears the steepest slopes we track, rated to 80%, and its all-wheel drive grips grades a two-wheel mower slips on, from $1,399.99.
For a yard under heavy tree cover, the MOVA LiDAX Pro 800 is the safest pick: it navigates by LiDAR mapping rather than depending on a clear-sky satellite lock, from $849.
Price is the cheapest current retail price we track, cited to the listing that states it. Availability is the latest stock status. Max area and slope are the manufacturer's rated maximums on an open lawn. 39 available.
Rated maximum coverage area for each model, scaled to the widest (10,118 m²). Every figure links to the manufacturer spec.
Rated maximums on an open lawn: a complex, obstacle-filled yard covers less per session, so read it as a guide, not a guarantee.
Blades, garages, RTK antennas and more, each with an honest verdict on whether it is actually worth buying.
BestRobotMower.co ranks by the underlying data (price and specs), and a partner never changes a price or a spec. Partner status is one bounded, disclosed signal in how results are ordered: all else equal it can lift a partner above a comparable option, but never above a clearly cheaper one, and every partner is labeled. We show a figure only when we have a real source for it; when we do not, we show an honest gap, never an invented number.
Read the methodologyEvery major wire-free and RTK robot lawn mower from Segway Navimow, Mammotion, and Ecovacs, plus announced models. For each, we show the navigation type, rated lawn size and slope, cutting specs, the cheapest current price, and where to buy it.
Specs come from each manufacturer's own published spec sheet; prices and availability come from Amazon and the brand stores, verified on a cadence. Every figure links to the exact source that states it. Coverage and slope are rated maximums on an open lawn.
Wire-free means no buried perimeter wire: you set the boundary in an app. RTK is one way to do that (centimetre satellite positioning); others use camera vision or LiDAR with beacons. RTK needs a clear sky view, so heavily shaded yards may prefer a vision or LiDAR model.
No. BestRobotMower.co is an independent comparison site, not a manufacturer or a retailer. Some outbound links are affiliate links (including Amazon Associates); they never change the price you pay or a spec. Always confirm the current spec and price with the seller before buying.
