Abstract:
The invention relates to a vacuum cleaning device with a tank-type vacuum cleaner, a suction hose which is connected to the housing of the tank-type vacuum cleaner, and a filter bag. The tank-type vacuum cleaner has a motor fan unit which is designed such that the average electric input power of the fan unit ranges from 1000 W to 200 W and results in a vacuum of more than 12.5 kPa in the measuring chamber when using aperture 6 and a vacuum of more than 4.0 kPa in the measuring chamber when using aperture 8 in the event of an average electric power input ranging from 1000 W to 800 W; a vacuum of more than 10.0 kPa in the measuring chamber when using aperture 6 and a vacuum of more than 3.4 kPa in the measuring chamber when using aperture 8 in the event of an average electric power input ranging from 799 W to 600 W; a vacuum of more than 7.0 kPa in the measuring chamber when using aperture 6 and a vacuum of more than 2.5 kPa in the measuring chamber when using aperture 8 in the event of an average electric power input ranging from 599 W to 400 W; and a vacuum of more than 4.0 kPa in the measuring chamber when using aperture 6 and a vacuum of more than 1.4 kPa in the measuring chamber when using aperture 8 in the event of an average electric power input ranging from 399 W to 200 W. The suction hose has an average cross-sectional area of at least 9 cm2, in particular at least 11 cm2 or 13 cm2, and the filter bag has a bag surface area between 2500 cm2 and 5000 cm2 and is a disposable filter bag made of a nonwoven fabric.
