Possible Causes
Dust bin full or clogged, Primary filter or HEPA filter heavily clogged, Suction inlet blocked by debris, Fan (vacuum) motor failing or obstructed
How to Fix / Troubleshooting
Safety first: Turn off the robot and remove it from the dock. Do not run the robot without filters unless the manual explicitly allows it for testing.
- Empty dust bin: Remove the dust bin and empty all debris.
- Clean filters: Take out the primary and HEPA filters. Tap them gently over a trash can to remove dust. If washable (check Eureka manual), rinse with water and allow to dry completely (at least 24 hours) before reinstalling.
- Check suction path: Inspect the dust bin inlet and suction channel inside the robot for blockages. Remove any clogs.
- Test suction: Reinstall the bin and filters, power on, and start cleaning. Listen for normal fan sound.
- If E8 persists or fan is silent: The Suction Fan Motor Assembly may be burnt out or jammed. Replacement requires opening the robot, disconnecting the fan module, and installing a new one. This is best done by a qualified technician.
