How to Fix / Troubleshooting
Safety first: Remove the battery and do not continue using the vacuum if you smell burning or see smoke.
- Visual inspection: Check the main body vents for signs of overheating or burning smell.
- Power reset: Remove the battery for several minutes, then reinstall and test.
- Avoid moisture: Ensure the vacuum has not been used to pick up liquids or in very humid environments. Allow to dry thoroughly if moisture is suspected.
