Possible Causes
Dust bin full, HEPA filter clogged, Suction channel blocked, Fan motor failing
How to Fix / Troubleshooting
Safety: Turn off the robot and remove the dust bin.
- Empty dust bin: Open the dust bin and empty all debris into a trash bag.
- Clean HEPA filter: Remove the HEPA filter from the bin. Tap it gently against the inside of a trash can to remove dust. If washable (check Laresar manual), rinse with water and allow to dry completely for at least 24 hours before reinstalling.
- Inspect suction path: Look into the suction inlet on the robot and the outlet on the dust bin. Remove any clogs (paper, hair balls, large debris).
- Check fan noise: With the bin removed, briefly power on the robot and start suction (if allowed). Listen for abnormal grinding or no spin from the fan motor.
- Reassemble and test: Reinstall the dry filter and dust bin. Start a cleaning cycle and check suction strength.
- If E8 persists or suction is still weak: The internal suction fan motor may be failing and needs replacement.
