How to Fix / Troubleshooting

Safety first: Turn OFF the vacuum, remove the battery, and detach the floor nozzle.

  • Inspect brush roll: Remove the brush roll from the nozzle. Check for cracks, broken end caps, or bent shafts. Replace the brush roll if damaged.
  • Check gearbox area: Open the side cover (if accessible) where the belt or gears are located. Remove any debris and inspect gears for missing teeth.
  • Reassemble and test: Refit the brush roll and covers securely. Reinstall the battery and test the nozzle. If clicking persists, the internal gearbox or motor may be damaged.

When to call a technician: Internal gearbox or motor replacement in the nozzle is best handled by an ETA service center or by replacing the entire motorized nozzle assembly.
