Robot vacuum frequently reports that the dust bin is full even after emptying.

Safety first: Turn OFF the robot and remove the dust bin.

• Clean sensor: Locate the small optical dust sensor window inside the bin or bin cavity and gently clean it with a dry cotton swab.
• Check flaps: Ensure any internal flaps or doors in the bin move freely and are not jammed with debris.
• Auto-empty check: If using an auto-empty dock, verify the dock bag is not full and that the suction port is not clogged.
• Test: Reinstall the bin and run a short cleaning cycle to see if the warning returns.
• If false alerts persist: The dust sensor or bin detection circuit may be faulty and require replacement.
