PURPOSE:To enable a window glass sheet to be cleaned over the whole width with a proper constant force by enabling a squeegee to be brought in contact with or to be separated from a glass surface, and the angle of the squeegee to be regulated, and by detecting the position of the squeegee and a pressure-applying force to the glass surface, to feedback-control the pressure-applying force and the angle of the squeegee. CONSTITUTION:When an upper side rail detecting sensor 34 with a photoelectric sensor is turned ON by the descending of an equipment 11, then an approach and separation servo-mechanism 15 is worked, and a squeegee 14 is extended to a window glass W side at a high speed and is extended till the approach of the window glass sheet W is detected by a glass approach detecting sensor 36. When the approach is detected, then the extending speed of the squeegee 14 is switched to a low speed, and the pressure-applying force A of the actual squeegee 14 from a pressure sensor 21 is compared with the set value B of the pressure- applying force at the time of starting cleaning, and a head case 12 in the equipment 11 is moved upward and is stopped when the set value B is set, and the cleaning of the window glass sheet W is started. In this case, angle regulation with the microspeed of the regulation servo-mechanism 16 of the squeegee 14 is performed, and sprinkling is started by a sprinkler. At the same time, the squeegee 14 is switched into a set state at the time of continuous cleaning, and feed-back control is performed.
