A vacuum arrangement has a vacuum pipe having a vacuum opening facing a ground surface and adapted to pick up from the ground surface a material to be collected. The vacuum pipe conveys the material to be collected into a collecting container connected to the vacuum pipe. The vacuum pipe has a working area located within the area of the vacuum opening. At least one blower nozzle having a blower air exit is arranged such that a blower air flow exiting from the blower air exit is directed onto the ground surface into the working area. The blower air exit and the vacuum opening are positioned at a spacing relative to one another.

Vacuum arrangement for a ground area

A blower having a discharge tube, which can be secured to a housing, for guiding a stream of air is provided. The air stream flows in a main stream direction in the discharge tube and in a discharge stream direction out of the discharge tube. The discharge stream direction forms an angle of greater than 0&#xb0; with the main stream direction. The discharge stream direction has a transverse component that extends perpendicular to the main stream direction, which produces a force in the discharge tube perpendicular to the main stream direction. To reduce the transverse force produced in the discharge tube, a partial air stream is branched off out of the discharge tube and flows in a partial stream direction that has a compensation component that is directed opposite to the transverse component.
