The numbers that matter first, then every fact by group. As published by the maker or the store we read it from.

Navigation and obstacles 1 fact

The highest threshold the robot takes, as the maker states it. Measure your own: the step into a bathroom or onto a balcony is often higher.

- Robot height
How tall the robot is. It decides whether it fits under your sofa, bed or cabinet.
- 2.9 in (7.3 cm)
