Possible Causes
Clogged filters, Blocked suction inlet or air channel, Worn or damaged suction fan, Air leaks around dustbin or seals
How to Fix / Troubleshooting
Safety first: Turn the robot OFF and remove the dustbin before cleaning.
Step-by-step:
- Empty and clean dustbin: Remove all debris and wipe the bin interior.
- Clean or replace filters: Tap the primary and HEPA filters to remove dust. Replace them if they are heavily soiled or older than the recommended interval.
- Check suction path: Inspect the main brush channel and suction inlet for blockages. Use a small brush or vacuum to clear any clogs.
- Inspect seals: Check the rubber gasket around the dustbin and suction inlet for cracks or misalignment. Reseat or replace the dustbin seal if damaged.
- Test suction: With the robot ON and running, feel for airflow at the exhaust. If airflow is still weak, the suction fan motor may be worn and require replacement.
When to stop: If cleaning and filter replacement do not restore suction, fan module replacement is recommended.
