摘要： A vacuum cleaner capable of more efficiently cleaning narrow spots while effectively avoiding an object. An object sensor provided in a main casing detects the presence or absence of an object within a specified distance in a plurality of directions on a forward side of the main casing. A control unit controls operation of driving wheels, based on detection of an object by the object sensor to thereby make the main casing autonomously travel. When an object is detected by the object sensor, the control unit controls the operation of the driving wheels, so that the main casing is swung to an angle corresponding to a direction of the detected object to thereby make a side portion of the main casing face the object.
