Roomba Error 26: Vacuum Motor Suction Blocked

Quick Answer

Roomba Error 26 means the vacuum motor suction is blocked. The most common cause is a clogged filter (50% of cases). Remove the dustbin, pull out the filter, tap it clean over a trash can, and reinsert. Also check the intake port inside the bin cavity and the port connecting the bin to the suction channel for packed debris. Run a test cycle after cleaning. If Error 26 persists after clearing all blockages, the vacuum motor impeller may have failed.

Frequently Asked Questions

How often should I replace the Roomba filter to prevent Error 26?

iRobot recommends replacing filters every 2 months in normal use, or every month in homes with pets. Regular tapping clean between replacements extends filter life. A clogged filter is the leading cause of Error 26.

Can I wash a Roomba filter?

Only filters specifically labeled as washable (some e and i series filters) can be rinsed with water. All other Roomba filters are dry-clean only. Washing a non-washable filter destroys the filter media and causes debris to pass through to the motor.

My filter is clean but Roomba still shows Error 26. What else should I check?

With a clean filter, check the suction intake port in the bin cavity and the port on the main chassis where the bin docks. Compact debris can build up in these openings over time. Also check the main brush channel for a jam since a brush blockage can overload the motor circuit and trigger Error 26.

Is the vacuum motor replaceable on a Roomba?

Yes, but it is an advanced repair. The vacuum motor module is located inside the Roomba chassis and requires removing multiple panels and disconnecting several wire harnesses. Replacement motors cost $15-40. Given that cost approaches a significant fraction of a budget Roomba's value, compare repair cost versus a refurbished unit.

Does running over wet carpet or a spilled liquid cause Error 26?

Running over moisture can allow wet debris to pack against the filter and intake, causing Error 26. If Roomba ran through a wet area, remove the filter immediately and let it and the bin cavity air-dry completely before running again.
