摘要： In a first mode, a control unit controls operation of driving wheels so that a main casing is made to travel straight and, upon detection of an object by an object sensor, the main casing is changed in traveling direction and made to travel straight. In a second mode, the control unit controls the operation of the driving wheels so that the main casing travels in a curved shape along an object detected by the object sensor. When a charging device is not found by a signal reception part during traveling within a region by the first mode, the control unit is changed over to the second mode. The control unit is changed over to the first mode when it is decided a specified number of times or more that the main casing has moved to a different region by the second mode.

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.
