Error 11, Roomba® j Series and Combo 10 Max

Error eleven (11) means the vacuum is experiencing insufficient airflow. You may need a replacement Cleaning Head Module.

1. Begin by removing the Cleaning Head Module by following the instructions for changing the Cleaning Head Module.
2. Next, inspect the fan/scroll/vacuum assembly for debris. Be sure to inspect both the entrance and exhaust.
3. Remove any debris using compressed air (or Air Duster).
4. Replace the bin filter.
5. Rotate the metallic portion of the vacuum motor three full rotations.

• Clockwise
• Then counterclockwise
• If you are unable to rotate the vacuum motor:
  1. Elevate the robot 1 foot off a hard surface (be sure it is a surface or item of furniture that you are willing to potentially scratch or damage, such as a work bench) and drop it. (Optional or use instead of compressed air).
  2. Repeat the scroll clearing step.
  3. Replace the Cleaning Head Module after two attempts if the error was still persisting.
