Robot vacuum frequently reports that the dustbin is full even when it is nearly empty (no explicit code shown).

Safety first: Turn the robot OFF and remove the dustbin.

• 1. Thoroughly clean filters: Tap or replace the HEPA and pre-filters to restore airflow.
• 2. Inspect bin seals: Check the rubber gasket around the dustbin opening for damage or misalignment. Reseat or replace if needed.
• 3. Clean airflow path: Use a soft brush to remove dust from the suction channel and any visible sensor ports.
• 4. Reset robot: Power cycle the robot and run a short cleaning test.
• 5. Replace filters or sensor: If false full indications continue, replace the filter set first; if still unresolved, the airflow sensor may need replacement.

Warning: Do not poke sharp objects into sensor ports; this can damage delicate diaphragms or optics.
