Abstract
A cleaning device for cleaning an outer portion of a sensor includes: a pump connected to an air supply line; a pressure accumulator connected to the pump in a housing of the cleaning device, which can be mounted on the sensor; and an exhaust air duct with a pressure-controlled valve connected to the pressure accumulator and connected to at least one nozzle which is aligned on the outer portion to be cleaned. The cleaning device is configured to perform pressure-surge cleaning operations in which air drawn in by the pump is compressed in the pressure accumulator, and the compressed air in the pressure accumulator is expelled as a pressure surge via the at least one nozzle when pressure exerted by the compressed air enclosed in the pressure accumulator exceeds a pressure value required to temporarily open the pressure-controlled valve.
