PORTABLE HARD SURFACE CLEANING DEVICE

The invention relates to a portable hard-surface cleaning device (10) for pulling off and suctioning liquid from a hard surface, in particular from a window pane, comprising a suction nozzle (136) having a suction opening (140), on which suction opening at least one pull-off lip (142, 144) is arranged, a drive chamber (19), in which a suction unit (22) is arranged, which has a suction turbine (24) and an electric motor (26) and which has a flow connection to the suction nozzle (136) in order to suck in a liquid-air mixture from the suction opening (140), a separation chamber (128), which is arranged in the flow path between the suction nozzle (136) and the suction unit (22) and in which a separating apparatus (130, 132) for separating liquid from the liquid-air mixture is arranged, and a dirty-liquid receptacle (18) for receiving the separated liquid. In order to be able to produce the hard-surface cleaning device (10) more economically, a motor housing (38) is arranged in the drive chamber (19), which motor housing surrounds the electric motor (26) and at least one rechargeable battery (48) and battery-monitoring electronics (49) in a spray-water-tight manner and which motor housing forms a lower housing part (32) of a turbine housing (28) arranged in the drive chamber (19), which lower housing part is supported by a support wall (64, 66), a turbine wheel (34) being rotatably supported in the turbine housing.
