Door tracks can collect grit in channels the robot cannot reach well. Treat robotic cleaning as maintenance of the surrounding floor, with the track cleaned separately.

A practical checklist
- Check the raised rail profile and route to the adjoining room.
- Vacuum loose dry grit outside the track before mopping.
- Use an appropriate manual tool for deep channels and corners.
What this looks like at home
A patio-door threshold may look low from indoors yet have a much sharper return edge from the conservatory.
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
Do not assume the robot's advertised climbing height covers a narrow metal rail.
