Error 16 means Roomba® is not able to start cleaning because it is tilted or the bumper is possibly dislodged from the robot. If found, use it to guide you through the steps on how to fix the bumper. If the bumper is not dislodged from the robot, move Roomba® to a flat surface, then press CLEAN to restart. Avoid moving the robot when pressing the CLEAN button. If Roomba® says this message on a flat surface.
- Press and hold the CLEAN button on the robot for 10 seconds until all the indicators illuminate. When the button is released, you will hear a series of tones.
- Press and release CLEAN once, then wait five (5) seconds.
- Press CLEAN to start a new cleaning job.
If you use the scheduling feature, open the iRobot® HOME App after rebooting to confirm that the schedule remains intact.
If the message persists, please contact iRobot Customer Care.
