1. A surface-cleaning device comprising a base part and a cleaning part which is provided with a substantially flat contact surface for making contact with a surface to be cleaned and which is journaled so as to be rotatable relative to the base part about an axis of rotation which extends substantially perpendicularly to the contact surface, wherein the cleaning part is pivotable relative to the base part about a pivot axis which extends transversely to the axis of rotation, while the base part is provided with means for exerting a pre-tension force on the cleaning part about said pivot axis such that when the device is moved over the surface to be cleaned, the cleaning part rotates about the axis of rotation only under the influence of a friction force present between the surface to be cleaned and the contact surface.
