FIELD: mechanical engineering, in particular, dust catching apparatus having shape allowing it to be detachably inserted into main casing of vacuum cleaner connected with vacuum suction chamber joined to air admission opening.
SUBSTANCE: dust catching device has first cyclone-type dust catching part and second cyclone-type dust catching part, said parts being designed for centrifugal separation of dust entrained by air sucked through air admission opening. First and second cyclone-type dust catching parts are extending substantially in parallel with opening of main casing of vacuum cleaner, said opening being adapted for admission of air therein.
EFFECT: increased sucking and dust separating capacity of apparatus.
