Cleaning device for selectively applying a first medium to a surface, comprising: - a high-pressure reservoir designed for storing the first medium under a reservoir pressure, in particular under high pressure, - a pulse nozzle designed for applying the first medium under the reservoir pressure to the surface in a pulsed manner, - a switching valve, characterized in that - the high-pressure reservoir and the switching valve are structurally integrated in a reservoir valve module, the switching valve being designed as a solenoid valve and comprising: - a nozzle port and a high-pressure reservoir port designed for selectively establishing a first connection between the high-pressure reservoir and the pulse nozzle, and - a feed port for establishing a second connection between the high-pressure reservoir and a first medium source, - the switching valve, in a release position (160.2), releasing the first connection between the high-pressure reservoir and the pulse nozzle via the high-pressure reservoir port and the nozzle port, and - the switching valve, in a loading position (160.1), releasing the second connection between the high-pressure reservoir and the first medium source (MQ1, MQ1') via a supply port, in particular feed port, and the high-pressure reservoir port, and - the switching valve being further designed for switching between the release position (160.2) to release the first connection and the loading position (160.1) to release the second connection, - the high-pressure reservoir port being under the reservoir pressure of the high-pressure reservoir and/or the supply port being under the pressure of the first medium source. - a high-pressure reservoir designed for storing the first medium under a reservoir pressure, in particular under high pressure, - a pulse nozzle designed for applying the first medium under the reservoir pressure to the surface in a pulsed manner, - a switching valve, characterized in that - the high-pressure reservoir and the switching valve are structurally integrated in a reservoir valve module, the switching valve being designed as a solenoid valve and comprising: - a nozzle port and a high-pressure reservoir port designed for selectively establishing a first connection between the high-pressure reservoir and the pulse nozzle, and - a feed port for establishing a second connection between the high-pressure reservoir and a first medium source, - the switching valve, in a release position (160.2), releasing the first connection between the high-pressure reservoir and the pulse nozzle via the high-pressure reservoir port and the nozzle port, and - the switching valve, in a loading position (160.1), releasing the second connection between the high-pressure reservoir and the first medium source (MQ1, MQ1') via a supply port, in particular feed port, and the high-pressure reservoir port, and - the switching valve being further designed for switching between the release position (160.2) to release the first connection and the loading position (160.1) to release the second connection, - the high-pressure reservoir port being under the reservoir pressure of the high-pressure reservoir and/or the supply port being under the pressure of the first medium source.
