Why does the robots rear end back up against charging base sometimes?
In this case, the reason is usually that the robot has not made charging contact so it keeps on driving backwards. Try taking a dry cloth and wipe clean the charging contacts on the back of the robot as well as wipe clean the charging contacts on the charging base. Make sure the base is not tilted so both contacts on the Neato touch the power strips on the base. Try letting the robot clean a room and dock at the end to see if this has solved the problem. 7.
