Coredy Main Brush Drive Failure without Code

Robot vacuum’s main brush does not spin, but suction and movement are normal.

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

Main brush motor failure, Broken drive gear, Brush not seated correctly

Safety first: Turn OFF the robot and flip it over.

Reseat brush: Remove the main brush and reinstall it, ensuring the drive end is fully inserted into the motor side slot.
Check guard: Make sure the brush guard is latched securely; some models will not drive the brush if the guard is open.
Inspect drive gear: If accessible, check for broken or stripped gears in the brush motor housing.

If the brush still does not spin, the main brush motor assembly likely needs replacement.
