ABSTRACT:
A sweeping machine has two circular brooms at the front region of a housing rotating towards the inside in opposing directions. Inside the housing and adjoining a sweeper plate across which the circular brooms sweep, a cylinder broom sweeping in a direction towards the front region is arranged. The cylinder broom picks up the refuse swept by the circular brooms and sweeps up dusty refuse in particular from the ground and throws both of these together backwards into the housing into a refuse container.
