How to Fix / Troubleshooting
Safety first: Remove the battery and do not continue to run the vacuum if it makes grinding or high-pitched squealing noises.
- 1. Check for external obstructions: Remove the dust bin and inspect the motor inlet area for debris or foreign objects that may have been sucked into the fan.
- 2. Listen to the motor: With attachments removed, briefly power on the unit (battery reinstalled) and listen. If the motor sounds rough or wobbly, stop immediately.
- 3. Inspect for burning smell: A burnt odor indicates motor winding damage. Do not continue using the vacuum.
- 4. There are no user-serviceable parts inside the motor housing. Replacement of the main motor assembly or entire main body is typically required and should be done by an authorized technician.
