iRobot Error 29 on Roomba: started during a software update

Pause schedules during the update

What it means
In iRobot's i Series chart, Error 29 is an error while upgrading software; the Error 29 article says the robot was started while an update was being performed. The robot's control software was interrupted by a cleaning start, so the code describes timing, not a damaged part. The light ring tells you the state: a white clockwise swirl means starting up or updating. The code does not prove the robot or its electronics are faulty: iRobot's step is to leave it on the dock until the update processes fully.
