Coredy Excessive Noise from Suction Fan or Brush

Robot vacuum is very loud during operation compared to normal, especially from the suction area.

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

Debris in suction fan, Worn fan bearings, Main brush bearings dry or damaged

Safety first: Turn OFF the robot and remove the dust bin.

Clean suction path: Inspect the suction inlet and dust bin for foreign objects (coins, small toys) and remove them.
Check main brush: Remove the main brush and clean hair from the ends and bearing caps. Replace the brush if the shaft is worn or bent.
Listen for fan noise: Run the robot briefly without the main brush installed. If the loud noise persists, it likely comes from the suction fan motor, which may need replacement.
