Robot mowers, specs checked
The right robot for your lawn, with the specs checked.
Measure your lawn, check your slope, and see which robot mowers on sale in the UK are rated to cover it, with every spec taken from the manufacturer and dated. Wire, RTK, vision or LiDAR: we explain the trade-offs plainly.
We haven't tested these mowers; we compare published specs and independent sources.
Which robot mower fits my lawn?
Worked example
For a 450 m² garden in 2 zones joined by a 0.9 m side passage, a steepest slope of 25%, some trees near the edge and no boundary wire wanted:
- Navigation that suits it: Camera vision, LiDAR, Hybrid.
- Look for a model rated for at least 540 m² (your lawn plus our 20% headroom), at least 25% slope, multi-zone support and a body narrower than 0.9 m.
- Matching UK models appear here as each one is checked against the manufacturer's UK page.

Measure and decide
- Boundary wire or wire-free? DeciderAnswer six questions about your garden and see which navigation suits it: boundary wire, RTK satellite, camera vision, LiDAR or a hybrid, with the reasons and the trade-offs.
- Lawn area calculatorMeasure your lawn in m² from simple shapes or points round the edge, across several zones, minus beds and patios. The figure every robot mower spec is rated against.
- Lawn slope calculator (% and °)Turn a rise and a distance, or a phone spirit-level reading in degrees, into slope % and °, find your steepest section, and check it against a mower's rated maximum.
Guides
- Choosing and fitHow to choose a robot lawn mower that fits your garden: measure the lawn, find the steepest slope, count the zones and passages, then match them to manufacturer-rated specs.
- Wire, RTK and visionHow robot mowers find their way: boundary wire, RTK satellite, camera vision, LiDAR and hybrids. What each needs, where each struggles, and which suits your garden.
- Wildlife and safetyRobot mowers and hedgehogs: why daylight-only mowing matters, what the published research found, and how to make your garden safer for wildlife. Sourced, never self-rated.

Our wildlife-safe mowing pledge
We only ever suggest daylight mowing, never from dusk to dawn, when hedgehogs are out. Our schedules start after sunrise and finish before sunset. We never rate wildlife safety ourselves: we cite the published research instead.
