How to Fix / Troubleshooting

Safety first: Turn OFF the vacuum, remove the battery, and allow it to cool completely before further use.

  • 1. Clean vents: Use a soft brush or compressed air to clean all external vents on the main body.
  • 2. Verify filters: Ensure filters are correctly installed and not restricting airflow more than intended.
  • 3. Short test: After cooling and cleaning, run the vacuum for a short period. If it heats up rapidly again, stop using it.

Service required: Persistent overheating with clean vents and filters indicates internal motor or cooling path issues. The motor assembly should be inspected and replaced by a technician.
