An ultrasonic transmission / reception device 11 for controlling the posture and position of the cleaning device main body is mounted, and further, a dust absorbing paper 13 is mounted on a frame 12 removably fitted around the upper portion of the main body case 1 so that the cleaning device is mounted. The main body 14 is configured.

FIG. 3 is a side sectional view of a base station according to an embodiment of the present invention. An upper plate 15a of a base station case 15 is configured to receive a lower case plate 1a of the main body case 1 of the cleaning device main body 14. At the center of the upper plate 15a, a charging coil 16 which is in contact with the charging coil 4 mounted on the lower case plate 1a of the cleaning device main body 14 is mounted, and a charging circuit 17 for applying power to the charging coil 16 is provided with a base station case. 15 is installed inside,
Further, an ultrasonic vibrator 18 is attached to the center of the charging coil 16, and a high frequency output is applied to the ultrasonic vibrator 18.
