Abstract (en)
[origin: WO2020160945A1] The present invention relates to a dust suction device comprising a suction head (2), said suction head comprising at least one filter element (4), and the at least one filter element lying obliquely inside the suction head. A second aspect of the invention relates to a method for changing a filter element in a dust suction device, the replacement of the filter element being achieved from above, similar to a "top-loader" principle.
