The invention relates to a windshield wiper system and a method for operating a windshield wiper system. Operation of a windshield wiper system for cleaning a windshield of a motor vehicle includes driving at least one wiper by an electric drive motor so that the at least one wiper shifted between two terminal positions, processing by a control unit as the input variable the output signals of a rain quantity and the switching signals of a manually controllable switch mechanism, and processing as the output variable a supply voltage of the electric drive motor so as to control the wiper speed, operating the at least one wiper () with variable intermittent interval times and at variable wiper speeds, as a function of a rain quantity detected by the rain sensor (), so that the precisely one wiper speed and precisely one intermittent interval time are associated with each measured rain quantity, and moving the at least one wiper () in an intermittent mode with a lower speed than in a continuous mode.
