PROBLEM TO BE SOLVED: To provide a self-traveling vacuum cleaner capable of performing a cleaning while autonomic traveling with a simple structure at a low cost. SOLUTION: This self-traveling vacuum cleaner comprises a box-shaped steering and driving means 18 integrally rotatable with a vertical shaft 25, an electric blower 3 for generating an air flow for sucking dust, a bumper 24 arranged on the advancing directional side of a cleaner body 40, a traveling motor 10 for rotating a drive shaft 11 through the vertical shaft 25, and a rotatable movable member 29 having one end connected to the bumper 23 and the other end energized to the steering and driving means 18 side and attachably and detachably engaged with the steering and driving means 18. When the bumper 23 collides with an obstacle, the movable member 29 is rotated against the energization to release the engagement, and a prescribed quantity of load or more is applied to the vertical shaft 25 to integrally rotate the vertical shaft 25 with the steering and driving means 18, whereby the direction of the cleaner body 40 is varied to clean a floor surface F while self-traveling.
