Abstract: A cleaning machine, especially for professional cleaning, comprises two parallel and cylindrical brushes driven reversedly about a horizontal axis, the brushes being placed so closely together that the ends of the brushes in the plane defined by the rotational axes of the brushes almost join, touch one another or just overlap. Above said plane one or more sweepers in the form of bars, pipes, stretched wires or the like are arranged in the longitudinal direction of the brushes and extend into the course of rotation of the brush ends. There is a shield above the brushes for collecting the dirt that is thrown off them when meeting the sweepers. At the exterior of the brushes the shield ends in collecting receivers from which the collected dirt may pass to a collecting tank. This design proves capable of performing a simultaneous sweeping and washing of a floor. At the same time the construction is sufficiently compact to accommodate a polishing unit such that a simultaneous polishing of the floor is possible.
