ABSTRACT:
An automatic self-propelled vacuum cleaner includes an electrical power supply cord having a plug. The plug carries latches which can be coupled to either the vacuum cleaner or a wall-mounted socket. The vacuum cleaner carries a light beam receiver which receives a light beam signal emitted from the socket for guiding the vacuum cleaner toward the socket.
