FIELD: personal use articles.
SUBSTANCE: invention relates to a dust suction device containing a vacuum cleaner and a filtration bag where the filtration bag is represented by a filtration bag made of a non-woven material, a replacement filtration bag or a flat bag containing the first and the second filtration bag walls. The filtration bag has at least one surface fold, each surface fold having three areas lying within the filtration bag wall plane and areas that may project over the filtration bag wall plane so that to enable their unfolding during the vacuum cleaner operation. The vacuum cleaner has a hollow for accommodation of the filtration bag with rigid walls; provided for on the walls of the hollows for accommodation of the filtration bag is at least one first device ensuring holding at a distance (so that the device holds the areas lying within the filtration bag wall plane of at least one surface fold at a distance from the wall of the hollow for accommodation of the filtering bag) and at least one second device ensuring holding at a distance (so that the device holds the unfolded areas of at least one surface fold at a distance from the wall of the hollow for accommodation of the filtering bag).
EFFECT: design improvement.
