Abstract (en)
[origin: EP2653614A2] The device (1) has multiple air nozzles (4) arranged on two sides of a suction opening, and air guide elements (7) positionable adjacent to the suction opening for cleaning a surface. The guide elements deflect supplied pressurized air between the surface and the guide elements in a direction parallel to the surface after the pressurized air impinges on the surface. The guide elements are positionable parallel to the surface, and the air nozzles are arranged at a common retainer (3) and exhibit a distance of about 150 mm from the suction opening transverse to a suction direction.
