Patent abstract
A cleaning device with a frame can be driven on a ground surface and with a vibrating screen which is mounted on the frame such that it can be moved to a limited extent and which is connected to a contact element. A vibrating roller is attached to the frame such that it can be rotated about a rotary axis, and it has an outer surface, in which radial elevations are formed. A pre-tensioning element pre-tensions the vibrating screen such that the contact element lies against the vibrating roller.
