Abstract:
A cleaning device comprising a convex transfer surface disposed between a flat nozzle and a rotary brush. The flat nozzle is formed as a multichannel nozzle between the convex transfer surface and the apron with the bevel of the mouth of the multichannel nozzle ranging from 20 to 60 degrees from the horizontal plane. The clearance height between the convex transfer surface and the floor is preferably in the range of 1 to 8 millimetres.
