A cleaning device for a vehicle provides a liquid cleaning pulse and/or a compressed air cleaning pulse for a cleaning nozzle. The cleaning device includes a module compressed air connection for receiving compressed air and a pressure cylinder with a cylinder volume. A movable separator divides the cylinder volume into a compressed air receiving chamber and a cleaning liquid receiving chamber in a fluid tight manner. The air chamber has an air chamber connection which can be supplied with compressed air. Contraction of the liquid chamber occurs when filling the air chamber by moving the separator against a restoring force. A switching valve establishes a pneumatic connection between the module compressed air connection and the air chamber connection. A bypass valve establishes a pneumatic connection between the module compressed air connection and the compressed air nozzle line while bypassing the switching valve for providing a bypass compressed air flow.
