The fix
Roomba HEPA filter pack
Bin genuinely full, dirty bin sensor windows, or a clogged filter reducing airflow
Diagnose first: Empty the bin and wipe the two small IR sensor windows in the bin cavity before buying anything — that's free and fixes most cases. A filter replacement is only worth it if it's washable-and-worn or visibly clogged; on models like the j/Combo series this same restricted-airflow condition is what iRobot documents as the driver of the error, not a hardware fault.

How to fix it
- Empty the dustbin completely.
- Locate the two small clear sensor windows on the inside top corners of the bin cavity (on the robot, not the bin).
- Wipe these windows with a clean, dry microfiber cloth.
- Tap or wash the filter (model-dependent — only certain filters are washable).
- Reinstall and test.
Why it happens
Typical signs: 'Error 11' or 'empty Roomba's bin' voice prompt · Cleans for very short time before stopping · Reduced suction
- Bin actually full Self-explanatory — empty it.
- Dirty bin sensor windows IR sensors that detect bin fill level are covered in dust.
- Clogged filter Restricted airflow simulates a full bin to the sensor.
