Possible Causes

Worn motor bearings, Foreign object in motor fan, Damaged brush roll bearings, Loose screw inside nozzle

How to Fix / Troubleshooting

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

  • Isolate the source: Run a brief test with the floor head removed (battery refitted). If the noise disappears, the problem is in the nozzle; if it remains, the motor is suspect.
  • Inspect floor head: Remove the brush roll and check for stones, screws, or hard objects lodged in the housing. Spin the brush by hand to feel for roughness.
  • Check for loose parts: Tighten any visible screws on the nozzle housing.

If the noise clearly comes from the main body or motor area, the motor bearings or fan are likely damaged. Continued use can cause complete failure; motor assembly replacement by a technician is recommended.
