This working head consists of two parts 1 and 2 that can be put together at different levels of interlocking as a means of regulating the height between the foot 10 equipped with the cleaning accessories such as brushes, abrasive substances and cloths, and the dirt collection and suction device 3 and 4. The gap between the rear edge in the working direction of this foot and the cleaning scraper support represents the suction slit 19. This head is intended to be fitted to cleaning equipment designed both to spread a cleaning liquid and to remove the dirt by suction. <IMAGE>
