A device for cleaning wall surfaces, ground surfaces, track superstructures or tunnel walls is configured to be arranged on a rail vehicle that moves along a direction of travel. The device includes an aspirator opening and at least two air nozzles arranged in rows of air nozzles disposed on either side of the aspirator opening such that the aspirator opening is disposed between the rows of air nozzles. The rows of air nozzles are supplied with compressed air such that the pressure of the row of air nozzles disposed in front of the aspiration opening in the direction of travel of the rail vehicle is lower than the pressure of the other row of air nozzles.
