<p>PROBLEM TO BE SOLVED: To provide an electric cleaner capable of easily arranging a beacon device so that a camera can easily, surely image an object.SOLUTION: A beacon device 13 includes indication means 72 that can variably set a direction toward an object P. The beacon device 13 includes a beacon device light-emitting unit transmitting an induction signal for induction of an electric cleaner main body 11 to correspond to the direction indicated by the indication means 72. The beacon device 13 includes display means 73 indicating a predetermined direction. Control means has a photographic mode for traveling the main body case 20 so as to approach the beacon device 13 in response to the induction signal received by the light-receiving unit, and causing a camera 35 to image the subject P in the direction indicated by the indication means 72 on the basis of the induction signal when the main body case 20 is at a position of a predetermined length to the beacon device 13.</p> |
