How to Fix / Troubleshooting
Safety first: Remove the battery and allow the unit to cool completely before working on it.
- Perform full cleaning: Empty the dust cup, clean the cyclone, and thoroughly clean or replace all filters.
- Clean cooling vents: Use a soft brush or compressed air to clear dust from the motor housing vents. Do not use liquids.
- Shorter duty cycles: Avoid running the vacuum continuously on high power for long periods. Allow 10–15 minutes of rest after extended use.
- Check for unusual noise: If the motor sounds rough or squeals, the bearings may be failing, causing extra heat. In that case, the motor housing assembly should be replaced.
