How to Fix / Troubleshooting
Safety: Remove the battery pack and allow the unit to cool for at least 30 minutes before further use.
- Clean all filters: Remove pre-motor and HEPA/post-motor filters. Tap off dust and wash if the manual allows. Let them dry completely before reinstalling.
- Check for blockages: Inspect the cyclone, bin inlet, wand, and nozzle for obstructions that could restrict airflow.
- Inspect motor vents: Look at the air vents around the motor housing. Use a soft brush to remove dust buildup.
- Reduce load: Avoid using MAX mode continuously on thick carpets. Alternate between power levels.
- If overheating recurs quickly: The motor bearings may be worn, causing excess heat. Continued use can cause permanent damage; have the motor assembly inspected or replaced by a technician.
