Robot vacuum’s side brush spins too slowly or intermittently without showing an error code.

Safety first: Turn the robot OFF before working on the side brush.

• 1. Remove and clean side brush: Take off the side brush and remove any hair or debris from the hub and shaft.
• 2. Reinstall securely: Reattach the side brush and tighten the screw firmly, but do not overtighten.
• 3. Test operation: Run the robot and observe the side brush speed. Compare to video or documentation if unsure.
• 4. Replace side brush motor: If the brush still runs slowly or intermittently, replace the Electrolux side brush motor module.
• 5. If issue remains: The motor driver circuit on the main PCB may be weak and require board replacement.
