A cleaning device for cleaning a transparent element of an optical or optoelectronic device with a fluid cleaning agent, includes a housing in which the device is arranged, at least one fluid inlet arranged in the housing, and at least one nozzle supplied from the fluid inlet. The nozzle is designed to deflect a cleaning agent jet onto the transparent element, and the jet direction of the cleaning agent jet is substantially transverse to an optical axis of the transparent element. The fluid inlet is designed for a throughflow of a cleaning liquid out of a hydraulic channel and compressed air out of a pneumatic channel. The hydraulic channel has a hydraulic nonreturn valve, and the pneumatic channel has a pneumatic nonreturn valve, the nonreturn valves opening the channels in the direction of the nozzle and blocking the channels in the opposite direction.
