Abstract
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.
