Abstract
A vacuum cleaning device comprises a unit () for aerodynamically affecting dust particles and/or a surface () to be cleaned in order for the particles to become dislodged from the surface () and to be received by the unit (). The unit () comprises a housing () having an internal space () enclosed by a housing wall () in which at least one opening () is arranged, a movable surface () which is integrated in the housing wall (), and means () for actuating the movable surface (), which are adapted to realize an oscillating movement of the surface () that causes air to alternately be drawn into the housing () through the opening () and expelled from the housing () through the opening (). At least a portion of the housing wall (), particularly a portion of the housing wall () in which the opening () is located, is movably arranged in the unit ().
