How to Fix / Troubleshooting

Safety: Remove the battery before opening the housing. Do not run the vacuum with covers removed.

  • 1. Confirm source of noise: Remove the floor nozzle and wand, then run only the handheld unit. If the noise persists, it is likely the main motor.
  • 2. Check for foreign objects: Inspect the motor air inlet for debris that may be contacting the fan.
  • 3. Avoid further damage: If the noise is metallic or very loud, stop using the vacuum to prevent complete motor failure.

Motor bearing or fan issues generally require replacement of the entire motor assembly. This is a complex repair best done by a technician.
