    摘要: In order to reduce the energy consumption of the suction unit, on the one hand, and to improve the cleaning effect, on the other hand, of a wiper device for hard surfaces, in particular a window wiper, comprising a slit-shaped suction nozzle, on which a flexible wiper lip is arranged, which protrudes forwardly beyond the suction nozzle, it is suggested that the wiper lip be held on a wall of the suction nozzle and drawn against the opposite wall of the suction nozzle under the influence of a suction stream in the suction nozzle and thereby close the suction nozzle.
