The invention relates to a vacuuming device which comprises a vacuum cleaner and a bag filter and in which the vacuum cleaner has a rated input power of less than 1200 W, preferably less than 1100 W, especially preferably less than 900 W, the vacuum cleaner has a motor-fan unit and a regulation device that regulates the vacuum cleaner in such a way that the air flow is kept essentially constant at a minimum value of 34 l/s, preferably essentially constant at a minimum value of 37 l/s, especially preferably essentially constant at a minimum value of 40 l/s when the bag filter is loaded with DMT8 test dust according to EN 60312, and the bag filter is a disposable filter that is made of nonwoven fabric and has a drop in air flow of less than 15 percent, preferably less than 10 percent, especially preferably less than 5 percent when testing the reduction in maximum air flow with a partly filled dust receptacle according to EN 60312. |
