Excessive vibration felt in handle and housing while vacuum is running

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

Damaged or unbalanced fan impeller, Debris stuck on fan blades, Loose motor mounting screws, Cracked motor mount

Safety first: Remove the battery before further inspection.

Check for obvious debris: Inspect the inlet and filter area for large debris that may have partially entered the fan.
Verify assembly tightness: If accessible, check that the motor housing and container are properly latched and that no external screws are missing.
Do not ignore vibration: Persistent heavy vibration indicates internal damage and can lead to failure.
Professional repair: A technician should inspect and replace the fan or motor mount as needed.
