How to Fix / Troubleshooting
Safety: Turn OFF the vacuum immediately and remove the battery to prevent further damage.
Basic inspection:
- Check for loose parts or debris in the dust container and air path that might be contacting the fan.
If the noise clearly comes from the motor housing and persists, the motor bearings or fan are likely damaged. Continued use can lead to complete motor failure or overheating. The motor assembly should be replaced by a qualified technician.
