Abstract: The invention relates to a cleaning device (10) for an environment recognition device (100) of a vehicle, the environment recognition device (100) comprising a sensor (104) having a vision window (106) to be cleaned, wherein the cleaning device (10) comprises at least one first cleaning element (12) designed as a spray nozzle (14) for applying a cleaning liquid (1) to the surface of the vision window (106), and comprising at least one second cleaning element (32) designed as a nozzle for generating compressed air that acts on the vision window (106).

Abstract: The present invention relates to a cleaning device (1) for a detection system (2) in a vehicle, comprising an air circuit (4) and a liquid circuit (7) configured to spray air and liquid on the detection system (2), the cleaning device (1) comprising a first chamber (6) and a second chamber (9). The first chamber (6) is configured to be filled by one of air and liquid, whereas the second chamber (9) is configured to be filled by the other one of said air and liquid. The total volume of the first and second chambers (6, 9) is fixed, and the cleaning device (1) is configured to vary the volume of one of the first and second chambers (6, 9) so as to change the pressure in the other one of the first and second chambers (6, 9).
