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.

Claims
