  • a traffic infrastructure For the pneumatic removal of dirt from at least one surface of a traffic infrastructure are known from the prior art, for example from the DE 2452633 A1 or the FR 2999196 A1 , Devices known which are movable by a vehicle along a traffic route. With traffic infrastructure, roads are typically Track systems or tunnels with at least one tunnel wall, meant. These known devices each have a hood, the opening of which faces the surface to be cleaned and in which there are at least one blowing device and at least one suction device. Air flows out of the blowing devices in a direction of flow that runs essentially parallel to the opening of the hood to the surface to be cleaned or along the surface to be cleaned, swirls up from this contamination and is sucked away together with this contamination by the suction devices.
