Press the bumper if you need Roomba to replay the spoken error message.
This error occurred due to the following reasons:
- The error occurs on robots not equipped with rear cliff sensors when it is unable to back up any further due to a perceived safety issue.
- There is a limited distance that the robot can safely back up to ensure it does not fall backward down a cliff
- The error can occur if the robot gets stuck on a threshold, hung up near a chair, or gets into a situation where the bumper is hit when it does see an actual cliff
- Spinning in place depletes the amount of distance that the robot can back up
To recover from this error:
Move the robot to a new nearby location and press clean to resume the mission.
