Abstract: Apparatus for cleaning flat surfaces comprising a collector (1) for dust and liquid connected to a suction moto-ventilator group (2) and to a suction (3). A reservoir (4) for cleaning liquid is connected to an injection pump group (5), itself connected to a nozzle (6) provided in the suction, as well as an electrical control (7) for the suction group. The injection group, said collector (1) and the reservoir (4) are mounted removably on the upper surface (8) of a base (9) which encloses the suction group (2) and injection group (5). The base (9) comprises an arch (21) which extends above the upper surface (8) of the base (9) in a transverse plane and which comprises two lateral members (23, 26) and a medial member (22) mounted articulately on one of the lateral members. The medial member (22) has at its free end (24) a locking member (25) with the other lateral member ( 26). A retainer immobilizes the collector and the reservoir on the base (9) when the medial member (22) is locked.

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).
