ABSTRACT:
A sweeping vehicle for sweeping roads and other surfaces comprises a suction mouth located behind a sweeping brush. The inlet portion of the suction mouth is inclined relative to the surface to be swept and faces in a direction towards the brush. Air guide means extending from a trailing edge of the suction mouth approximately parallel to the surface, acts to direct air towards the suction mouth. The arrangement of the suction mouth and air guide means prevents particles of dirt from being discharged from the zone of the suction mouth by a vortex within the suction mouth.
