What it means
In iRobot's i Series chart, Error 19 means the robot failed to undock and may have bumped something near the Home Base. As it backs off the dock the robot relies on its bumper, wheels and the dock's signals, so objects around the Home Base or environmental interference at that spot can stop it. The code does not prove the robot or the Home Base is faulty: iRobot asks you to clear the area, move the Home Base and start the robot off the dock to see whether a different error appears.
