Possible Causes

Worn motor bearings, Foreign object in motor fan, Bent or chipped fan blades, Dust ingress into motor housing

How to Fix / Troubleshooting

Safety first: Remove the battery before inspection. Do not run the vacuum if the noise is very loud or accompanied by burning smell.

  • 1. Eliminate attachments: Run the vacuum briefly with no wand or floorhead attached. If the noise remains, it is likely from the main motor.
  • 2. Check for loose parts: Ensure the dust bin, cyclone, and filters are correctly seated and not vibrating.
  • 3. Inspect for debris near motor inlet: Look into the motor inlet behind the cyclone for any visible debris. Do not insert metal tools into the motor.

Persistent screeching or grinding indicates failing motor bearings or fan damage. The main motor assembly should be replaced; this is not typically user-serviceable.
