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).

An electronics component is protected against overheating with the aid of a liquid absorption unit. For this purpose, the electronics component, together with the liquid absorption unit are integrated into a housing device. The liquid absorption unit is made of a super-absorbent material which, when it comes into contact with an ingressing liquid, takes up the liquid and in so doing at least partially surrounds the electronics component. The super-absorbent material is selected such that it is also electrical insulating in the state in which it is fully soaked with the liquid.

A cleaning system for a sensor to be cleaned, comprising an accumulator comprising at least one cleaning fluid compartment provided with at least one tensioning element; a cleaning fluid inlet for receiving cleaning fluid; a cleaning fluid outlet for providing cleaning fluid in the form of a cleaning fluid jet; at least one gas compartment provided with at least one tensioning element; a gas inlet for receiving gas; and a gas outlet for providing gas in the form of a gas jet, a cleaning fluid electrovalve for controlling flow of cleaning fluid applied to the sensor to be cleaned, and a gas electrovalve for controlling flow of gas applied to the sensor to be cleaned.
