Abstract

The invention refers to a driving device for taking away filling material and particles soiling the filling material from a surface, in particular a sports field, preferably from an artificial lawn field. The driving device has a taking away device which removes the filling material and the particles from the field and puts it in the driving device, as well as a suction device with a filter element for separating particles from a suction air flow. The invention is characterised in that the filter element is self-cleaning.
