How to Fix / Troubleshooting

Safety: Immediately turn off the vacuum and remove the battery to prevent further damage.

  • Check for external causes: Ensure no loose parts in the bin or cyclone are contacting the fan inlet.
  • Inspect bin and cyclone: Remove them and look for foreign objects that may have been sucked into the motor inlet.

If noise persists with the bin removed, the motor bearings or fan are damaged. The motor assembly should be replaced by a qualified technician; continued use can lead to complete failure or overheating.
