Provided is an electric cleaning device (10) in which an electric vacuum cleaner body (11) can locate a charging device (12) more efficiently. A control unit (20) is provided with a first travel mode and a second travel mode. In the first travel mode, the control unit (20) controls the operation of a driving wheel so that a body case (15) moves straight ahead, and when an object is sensed by an object sensor (31), the body case (15) changes direction before traveling straight ahead. In the second travel mode, the control unit (20) controls the operation of the driving wheel so that the body case (15) is caused to travel in a curve while being made to follow along an object sensed by the object sensor (31). The control unit (20) switches to the second travel mode when the charging device (12) is not found by a reception device (33) upon said body case (15) traveling in a region in accordance with the first travel mode. The control unit (20) switches to the first travel mode upon determining, for at least a predetermined number of times, that the body case (15) has moved to a region in the second travel mode. |
