Robot mower ramps
A ramp lets a robot mower cross a step, kerb or raised edge between two parts of the lawn. We don't track any ramp products yet, because the major brands don't sell dedicated ones in the UK. This page explains when you'd need a ramp, what to look for in one, and the alternatives.

When you'd need a ramp
A ramp is only needed when the mower has to travel between two areas that aren't joined by a level route. Typical cases in UK gardens:
- A lawn on two levels joined by a garden step.
- A raised bed edge, sleeper border or kerb between the lawn and a path the mower must cross.
- A patio or decking threshold on the only route between front and back lawns.
- A lawn edge that drops onto a driveway the mower has to cross.
If there's already a level path, even a narrow one, you probably don't need a ramp. Check the mower's minimum passage width instead, and see our guide to complex gardens. If the two areas are completely separate, many mowers let you carry them between zones, which avoids building anything.
What to look for in a ramp
- Gradient. Compare the ramp's slope with the mower's rated slope percentage, and leave a generous margin. Wet grass, moss and algae all cut grip.
- Smooth transitions. A sharp change of angle at the top or bottom can ground the mower between its wheels. Long, shallow ramps are kinder than short, steep ones.
- Width. Wider than the mower, with room either side for navigation error. Wire-free mowers in particular need a margin.
- Surface. Something grippy that drains: artificial grass, rubber matting or real turf. Smooth painted wood or plastic becomes slippery when wet.
- Edges. A raised lip or low side rail stops a wheel dropping off the edge.
- Fixing. The ramp must not move when the mower drives on and off it.
Wired and wire-free mowers
For a wired mower, the ramp usually becomes part of a guide or boundary route. The wire has to run over or beside it, within the spacing the manual sets, and a ramp is a place where wire can be damaged. Follow the installation manual's rules for passages.
For a wire-free mower, you map the ramp as a channel between zones in the app. RTK models need decent sky view along the route, which can be poor next to a house or high wall.
Why we don't list ramps yet
The manufacturers we track don't sell ramps as accessories in the UK, and we only list products with manufacturer compatibility information. If that changes, or you know of one, tell us and we'll add it.
Frequently asked questions
Can a robot mower climb a kerb or step?
Only a small one. Robot mowers are built to roll over low bumps such as roots and lawn edging, not steps. Some manufacturers publish a maximum obstacle height, but many don't. Anything taller than that figure, or any step at all if no figure is given, needs a ramp or a different route.
How steep can a ramp be?
Keep it well inside the mower's rated slope, and gentler if the ramp will be wet or shaded. A ramp is a short slope with an edge at each end, and those transitions are where mowers tend to lose grip or catch their underside.
Can I make my own robot mower ramp?
Many people do, using sleepers, paving or compacted soil and turf. Make it wider than the mower, give it a grippy surface, avoid lips at the top and bottom, and fix it firmly so it can't shift.
Do wire-free mowers handle ramps better?
Not necessarily. They don't need a wire laid over the ramp, but they do need the ramp mapped as a route in the app, and satellite signal can be weaker if the ramp runs beside a wall or house.
