The fix
Roomba replacement filter
Vacuum motor airflow restricted by a clogged filter or blocked bin inlet
Diagnose first: Replace or clean the filter and clear the bin inlet first — iRobot's own guidance for this airflow error points at the filter roughly half the time. Only consider the vacuum motor module (a moderate-skill repair) if the error keeps returning with a clean filter and clear airway.

How to fix it
- Empty bin and tap out the filter — replace if more than 2 months old.
- Clear the bin inlet of any visible debris.
- Wipe the bin sensor windows in the robot's bin cavity (i/j/s series).
- Clean the brush area and extractors.
- If error persists with clean components, the vacuum motor module requires replacement.
