PROBLEM TO BE SOLVED: To solve a problem wherein dust is left in the neighborhood of a wall due to a gap between a floor cleaner and the wall when a self-propelled vacuum cleaner measures distances to the circumferential walls, and performs cleaning while moving based on the measurement. SOLUTION: The vacuum cleaner includes: a propelling means for moving a main body 1; a steering means for changing a movement direction; a cleaning means for performing cleaning; distance measuring means 10, 11 for detecting a distance to the wall; and a movement control means 9 to control the movement of the main body 1. The movement control means 9 includes a wallside movement means for moving the main body 1 apart prescribed distance from the wall. The cleaning means includes a cleaning nozzle 12, and a motor-driven blower 14. The cleaning nozzle 12 is protruded sideward at the both left and right sides or one side from the main body 1. Openings are arranged, to communicate with the motor-driven blower 14, at the whole part or a part of the protruded side surfaces. Thus, the cleaning nozzle 12 approaches the wall, sucks dust form the side surfaces, and collects dust in the neighborhood of the wall. COPYRIGHT: (C)2004,JPO
