Insufficient Cooling / Overload
Vacuum body becomes uncomfortably hot to touch during normal use
Advertisements
Possible Causes
Blocked cooling vents, Operating continuously on maximum power, Clogged filters increasing motor load, Internal motor wear increasing current draw
How to Fix / Troubleshooting
Safety first: Switch off the vacuum and remove the battery. Allow the unit to cool before handling.
- Clean vents: Use a soft brush or vacuum to remove dust from all ventilation grills on the motor housing.
- Service filters: Clean or replace pre-motor and HEPA filters to restore proper airflow.
- Adjust usage: Avoid running on maximum power for extended periods. Use medium or eco modes for general cleaning.
- Monitor temperature: After cleaning, run the vacuum and periodically check the housing temperature. Warm is normal; too hot to hold is not.
- Service if persistent: If overheating continues despite good airflow, the motor may be failing and should be replaced.
