A stationary side brush may be tangled, incorrectly fitted or inactive in that cleaning state. Check it during an actual clean rather than while the robot is parked.

Start with these checks
- Switch off and remove hair from the brush hub using the manual's removal method.
- Check the fixing is seated and the replacement part matches the model.
- Run a short clear-floor clean and note whether the brush starts then stops.
What this looks like at home
A brush that stops only when it meets a deep rug may be experiencing resistance rather than a permanent motor failure.
Follow the debris path
| Check | What matters |
|---|---|
| Floor opening | Look for lodged debris or a displaced brush cover. |
| Bin and seals | Check closure and seating after emptying. |
| Filter | Follow its own cleaning and drying instructions. |
A mistake to avoid
Do not overtighten a fixing or keep testing a seized brush motor.
Buy a part only after identifying the cause
Check the exact model and part reference before buying. If cleaning resolves the problem, a replacement may be unnecessary.

What the result tells you
If the brush starts on hard flooring and stalls on one rug, investigate that surface and the correct part before treating the motor as completely failed. Persistent non-operation on clear flooring warrants model-specific support.
