Error 44, Roomba Combo® j7+/ j9+ /10 Max

Error 44 means there is an issue with the pump activating when Roomba® is attempting the start a cleaning job. When this happens:

Ensure the following:

1. The tank is installed properly
2. A pad is installed on the robot, and the tank is full of water or an approved cleaning solution
3. The nozzles are free of debris
4. The water filter on the robot is free of debris. NOTE: If debris is found, remove the tank and filter and rinse with warm water.
5. Robot Reboot:
   1. Press and hold the CLEAN button on the robot for 20 seconds and then release
   2. When the button is released, the light ring around the CLEAN button will begin to swirl. NOTE: This will last for over one minute and means the robot is booting up. You will need to wait until the robot is fully booted up before pressing CLEAN to start a new cleaning job.

If all steps are followed and the issue persists, please contact iRobot Customer Care.
