At 9.7 cm it gets under your furniture. It's the one most homes should get: strong on carpets and hard floors, and the dock empties the bin and washes the mops.

Before you measure

Robot heights include the round sensor on top — that's the part that gets stuck. The Dreame L60 Ultra lowers its sensor to slide under, the others don't. Heights are the manufacturers' figures, rounded up.

A gap that's only just big enough can still trap a robot if the sofa sags or the carpet is thick. If it's within a few millimetres, assume it won't fit.

The dock needs room above it too: you lift the water tanks out of the top. Leave space on each side and in front so the robot can line up.

How we reached this verdict
