How to Fix / Troubleshooting

Safety: Turn off and remove the battery immediately to prevent further damage.

  • Isolate source: Run the vacuum briefly without the cleaner head. If noise disappears, the issue is in the head; if not, suspect motor or wand.
  • Inspect cleaner head: Remove brush bar and check for broken plastic pieces, stones, or screws inside the housing.
  • Check wand: Shake the wand and listen for loose objects; remove any found.
  • Motor noise: If grinding persists from the main body, the motor fan may be damaged. Motor replacement is required and should be done by a professional.
