A small internal step can divide a room into separate robot-cleaning areas. Mapping cannot overcome a physical level change beyond the machine's documented capability.
Table of Contents
A practical checklist
- Measure the step and assess both approach and return directions.
- Use a physical barrier where there is a fall risk.
- Plan separate supervised cleaning areas if the levels cannot be connected safely.
What this looks like at home
A sunken sitting area may need the robot carried down and back rather than a single whole-room routine.
Measure the profile in both directions
| Check | What matters |
|---|---|
| Rise | Measure from each side of the doorway. |
| Shape | Note sharp edges, slopes and narrow crests. |
| Return | Confirm the robot can get back to its charger. |
A mistake to avoid
Never disable cliff sensors to make a robot descend an internal step.
