Abstract
A de-dusting unit positionable in a vacuum chamber of a vacuuming device, where the vacuum chamber is delimited by a turbine, a first filter, and a second filter. The de-dusting unit includes a displacement module where the de-dusting unit is positionable within the vacuum chamber by the displacement module such that one of the first and second filters at a time is isolated from a suction flow and such that an oscillating movement of the de-dusting unit is transmitted to the isolated filter.
