iRobot Robot Vacuum Error 27 — Vacuum problem (vacuum motor overheated or stalled)
iRobot Robot Vacuum · Error code Error 27
What Error 27 Means
The vacuum (suction) motor is not functioning, most often because it overheated from a clogged filter or a blocked/failing impeller. The app reports it as 'Vacuum problem. See the app for help.'
Symptoms
- 'Error 27' voice prompt
- Brush or vacuum stops mid-cycle
- Unusual motor noise
Common Causes
A blocked filter starves the vacuum motor of airflow and overheats it — the most common trigger.
Dust packed around the vacuum impeller stalls it; inspect both the intake and exhaust sides.
If the error returns with a clean filter and clear airway, the vacuum motor/impeller itself is worn and the vacuum module needs replacement.
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.
