FIELD: personal use articles.SUBSTANCE: invention relates to a device for sucking dust, containing a vacuum cleaner and a filter bag, in which the vacuum cleaner has a nominal power input of less than 1200 Wt, preferably less than 1100 Wt and most preferably less than 900 Wt, and in which the vacuum cleaner comprises an assembly of a motor and a fan, and regulating device regulating the vacuum cleaner so that the air flow when filling the filter bag with the test dust DMT8 similar to EN 60312 is held substantially constant at a value of at least 34 l/s, preferably substantially constant at a value of at least 37 l/s, and particularly preferably substantially constant at a value of at least 40 l/s, and in which the filter bag is a removable filter bag of nonwoven material which when testing reduction of the air flow with partially filled container for dust similar to EN 60312 has reduction of the air flow less than 15%, preferably less than 10%, and particularly preferably less than 5%.EFFECT: improved operational reliability.15 cl, 6 dwg |
