How to Fix / Troubleshooting
Safety: Remove the battery before inspecting moving parts.
- 1. Check brush roll: Remove the brush roll and inspect for missing pieces, warped plastic, or heavy debris stuck on one side. Replace if damaged.
- 2. Test without nozzle: Run the vacuum with the nozzle removed. If vibration disappears, the issue is in the nozzle or brush roll.
- 3. Inspect motor fan: If vibration persists without the nozzle, open the motor housing and inspect the fan for debris or broken blades. Clean or replace the motor assembly if the fan is damaged.
- 4. Check motor mounts: Ensure rubber mounts or screws holding the motor are intact and tight.
- 5. Reassemble and test: After correcting any imbalance, reassemble and test at low then high power.
Persistent vibration can lead to premature wear of internal components; address promptly.
