Bosch Suction Motor Not Running

Robot vacuum is unusually quiet and appears to move but picks up almost no debris.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Disconnected suction motor connector, Failed suction motor, Faulty motor driver on mainboard

Safety first: Turn the robot OFF before inspection.

1. Check for airflow: With the robot ON and cleaning, place your hand near the exhaust vent. If there is no noticeable airflow and the robot is quiet, the fan is not running.
2. Confirm bin and filter placement: Ensure the dust bin and filter are correctly installed and not blocking a safety interlock.
3. Reboot robot: Power cycle the robot and test again.
4. If suction remains off: The suction motor or its wiring is likely faulty and requires professional repair.
