How to fix it
- Remove the bin and reinstall it firmly, making sure it clicks/seats fully.
- Empty the bin and check the bin inlet and airflow path for a blockage or jammed object.
- Restart the robot and press CLEAN to see if the motor activates.
- If the motor still won't turn on with a clear airway and a properly seated bin, the vacuum motor module has failed and needs replacement.
Why it happens
Typical signs: 'Error 11' / vacuum problem voice prompt · No vacuum motor sound when cleaning starts · Robot drives and brushes spin, but there's no suction
- Debris blocking the motor/airflow path An object or clump of debris jammed in the airflow path can prevent the vacuum motor from spinning up.
- Bin not fully seated On several models the vacuum motor won't activate unless the bin is properly closed and locked in place.
- Failed vacuum motor The vacuum motor itself has failed and will not activate at all.
