ABSTRACT:
A cleaning head for flat surfaces comprises a device (1) for distribution of cleaning liquid which comprises an injection pipe (2) connected to a washing device (3) located in a cleaning region (4) of the head, and a suction chamber (10) which is connected to a suction passageway (12) and which is disposed adjacent the cleaning region (4) between a scraper (13) and the washing device (3), so as to suck up the liquid and the dirt. The washing device (3) comprises a permeable body (5) onto which discharges the pipe (2) and which is flanked by two scrubbers (6, 7) comprising brushes disposed on opposite sides of the permeable body (5) and disposed substantially transversely to the surface to be cleaned. A second suction chamber (11) is disposed symmetrically relative to the permeable body (5) between one (7) of the brushes and a second scraper (14). The brushes (6, 7) and the scraping devices (13, 14) are disposed on the one hand symmetrically and parallel to the permeable body (5) and on the other hand transversely to the direction (D) of movement of the head.
