A machine for the cleaning of streets and in particular, the cleaning of pedestrian zones. The dust from the street is directed against a damp cloth by means of a rotating brush; the cloth is a partially permeable water sack on which the dust collects in scale-like masses. The scales fall from the sack and are thrown by brushes into a receiving means. The machine functions without a dust vacuum and therefore is relatively quiet.
