FIELD: personal use articles.
SUBSTANCE: invention is aimed depending on the projected versions and dimensions at "dry" cleaning streets, yards and premises, without the propagation of dust into the environment, without release of filtered air into the environment, with increased coverage of cleaning surface, with the collection-bagging of garbage in the airtight disposable recyclable standard or special reusable sacks/bags or a one-piece box, with the use of automatic unloading the reusable sacks/bags and cleaning of the filter. The closed circulation of air flow is provided by the use of internal return air duct (12), the side return air ducts (2) and active closed extension area of continuous simultaneous forced injecting-tapping of air (1). The device of expanding and retention in the expanded state of the sacks/bags is implemented using a perforated or mesh box (4), sealing (6) and hermetically sealed hatch (11), at that on the inner side of the walls and the bottom of the sack/bag (5) the force is applied pressing it to the walls of the perforated or mesh box (4) in movement of the air flow through the filter 8 from left to right - in the mode of garbage collection. The device of automatic unloading of reusable sacks/bags (5) and cleaning the filter (8) is implemented through the use of return-reverse air flow and manipulation with the lids/curtains of the special hermetically sealed hatches (7, 10, 11), shown in Table 1 together with the operating modes.
EFFECT: providing "dry" cleaning streets, yards and premises, without the propagation of dust into the environment.
