Possible Causes
Worn main motor bearings, Damaged brush roll bearings, Foreign object in fan, Cracked fan blades
How to Fix / Troubleshooting
Safety first: Turn OFF the vacuum and remove the battery.
- Isolate the noise source: Run the vacuum without the floor head (handheld only). If noise decreases significantly, the issue is in the head. If not, it is in the main body.
- Inspect brush roll: Remove and spin the brush roll by hand. Replace if it grinds or wobbles.
- Check for debris in head: Look inside the floor head for small objects contacting the brush or motor.
- Service main motor: If the loud noise persists in handheld mode, the main motor bearings or fan are likely damaged. This requires replacing the motor assembly.
