<P>PROBLEM TO BE SOLVED: To provide a self-propelled vacuum cleaner which moves around along the wall of a room while avoiding an obstacle without fail. Ž<P>SOLUTION: The self-propelled vacuum cleaner includes traveling means (2, 3) for moving a cleaner body 1; cleaning means (4, 5, 6) for performing cleaning; a distance measuring means for detecting a distance to a wall 13 or an obstacle; a signal detection part 8 for detecting electromagnetic waves; and a control means for controlling the traveling means and the cleaning means on the basis of the output signals of the distance measuring means and the signal detection part 8. The cleaning means performs cleaning by sucking dirt while traveling in the room where an external guide device 14 is installed. A signal line 15 is disposed in the room on a floor surface along the wall of the room and the edge of furniture installed in the room, and generates electromagnetic waves by the guide signals of a predetermined frequency applied from the external guide device 14. When the signal detection part 8 detects the guide signal, the control means controls the traveling means (2, 3) on the basis of the output signals of the signal detection part 8.
