Cordless vacuum makes grinding or rattling noises from the main body when running.

Safety first: Turn OFF the vacuum and remove the battery. Do not continue to run the unit with grinding noises, as this can cause further damage.

• Check for loose parts: Remove the dust bin and cyclone. Shake them gently to ensure no loose plastic pieces are entering the motor inlet.
• Inspect motor inlet: Look into the motor intake area for foreign objects (small stones, screws). Do not insert metal tools; use a plastic tool or vacuum with another cleaner if needed.
• Test without attachments: Reinstall the battery and run the main body alone for a few seconds. If grinding persists, the motor bearings or fan are likely damaged.

When to call a technician: Motor bearing or fan issues require replacement of the motor assembly. This is not user-serviceable and should be done by an ETA service center.
