Problems solved by technology

Furthermore, dust and dirt can collect under pieces of furniture that stand on legs.
With automatic, self-propelled vacuum cleaning devices, the available electrical power is limited due to the integrated power source.
While known vacuum cleaning devices are suitable for removing coarse, loose particles such as crumbs and fuzz from smooth floor coverings,

Embodiment Construction

[0022]Referring now in detail to the drawings, FIG. 1 shows a compact vacuum cleaning device 1 for automatic cleaning of smooth and textile floor coverings, particularly in the private home sector, having a housing 2, a suction mouth 3 that is disposed on the underside of a roller chamber 4, a cleaning roller 5 disposed in the roller chamber 4, a dust collection container 6, a suction fan 7, an electrical travel drive 8, control electronics 9, and a power source 10 in the form of two rechargeable batteries 11. Dust collection container 6 can be equipped with an air-permeable bag, and with a filter on the outlet side. The various components are disposed packed closely together in housing 2, for optimal utilization of space. Roller chamber 4 is mounted resiliently in housing 2, and cleaning roller 5, which is disposed in roller chamber 4 and configured as a brush roller, is driven by an electric motor 13, by way of a drive belt 12. From roller chamber 4, the air stream that enters thr...

Abstract

A compact vacuum cleaning device for automatic cleaning of smooth and textile floor coverings, particularly in the private home sector, has a housing, a suction mouth on the underside of the housing, a cleaning roller disposed in a roller chamber, a dust collection container, a suction fan, an electrical travel drive, control electronics, and a power source. The device height of the vacuum cleaning device is less than 180 mm. The maximal suction air stream that enters through the suction mouth, passes through the dust collection container, and leaves the vacuum cleaning device through the suction fan, is greater than 15 l/s. The maximal suction power is greater than 10 W.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a compact vacuum cleaning device for automatic cleaning of smooth and textile floor coverings, particularly in the private home sector. The device has a housing, a suction mouth on the underside of the housing, a cleaning roller disposed in a roller chamber, a dust collection container, a suction fan, an electrical travel drive, control electronics, and a power source. The height of the vacuum cleaning device is less than 180 mm. The height results from the distance above the floor that is predetermined by the travel drive, and from the dimensions of the housing that accommodates the dust collection container, the suction fan, the travel drive, the cleaning roller, the control electronics, and the power source. Antennas and any projecting fins that are intended to prevent the device from going under low pieces of furniture are not taken into consideration in determining the device height. Vacuum...
