Abstract

A self-propelled cleaning device has a surface cleaning system for cleaning a surface to be cleaned. In order to also be able to clean an above-floor surface, the cleaning device also has an above-floor cleaning element for mechanically cleaning an above-floor surface offset in terms of height relative to the surface. The above-floor cleaning element can be rotated and/or pivoted around a rotational axis, and at least one partial cleaning area of the above-floor cleaning element has a difference in height of roughly 3 cm or more relative to a lowermost standing surface of the cleaning device by comparison to a usual orientation of the cleaning device for a cleaning operation.
