The fix
Roomba replacement bin filter
Vacuum motor overheated from a clogged filter or blocked impeller
Diagnose first: A clogged filter overheating the motor is the most common trigger — replace the filter and clear the impeller path before assuming a hardware failure, and let the unit cool 30 minutes before retrying since this is a thermal fault.

How to fix it
- Remove and empty the bin, then replace (not just tap clean) the bin filter — a clogged filter is the most common cause.
- Inspect the vacuum airway and the fan/scroll (impeller) assembly for packed debris, checking both intake and exhaust; clear it with compressed air.
- Reboot the robot (hold CLEAN for 20 seconds) and let it cool for 30 minutes before retrying, since Error 27 is an over-temperature fault.
- Press CLEAN and listen for the vacuum motor spinning up. If it never runs with a clean filter and clear airway, the vacuum motor/module needs replacement — contact iRobot support or replace the vacuum module for your model.
Why it happens
Typical signs: 'Error 27' voice prompt · Brush or vacuum stops mid-cycle · Unusual motor noise
- Clogged bin filter A blocked filter starves the vacuum motor of airflow and overheats it — the most common trigger.
- Debris in the fan/scroll (impeller) assembly Dust packed around the vacuum impeller stalls it; inspect both the intake and exhaust sides.
- Failing vacuum motor If the error returns with a clean filter and clear airway, the vacuum motor/impeller itself is worn and the vacuum module needs replacement.
