Possible Causes

Restricted airflow through filters, Running continuously on maximum power, Dust buildup on motor cooling vents, Internal motor wear increasing heat

How to Fix / Troubleshooting

Safety first: Turn OFF the vacuum and remove the battery pack. Allow the unit to cool before further use.

  • Step 1 – Clean filters and vents: Ensure all filters are clean and correctly installed. Use a soft brush to remove dust from all external vents.
  • Step 2 – Reduce power setting: Use medium or eco mode for routine cleaning, reserving turbo mode for short bursts.
  • Step 3 – Limit continuous runtime: Allow short breaks during extended cleaning sessions to let the motor cool.

If the vacuum still becomes very hot quickly, internal motor or PCB issues may be present. Have a technician inspect the motor assembly.
