Error sixteen (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 the dislodged bumper to guide you through the steps for fixing the bumper. If the bumper is not dislodged from the robot, move Roomba® to a flat surface, then press the CLEAN button to restart. Avoid moving the robot when pressing the button. If Roomba® reports a message on a flat surface, reboot the robot.
- Press and hold the CLEAN button on the robot for nine (9) seconds until all the indicators illuminate. When the button is released, you will hear a series of tones.
- Press the CLEAN button to start a new cleaning job.
Note: 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.
