A wet cleaning device, in particular a wet wiping device, has a cleaning roller which is rotatable about a roller axis and has a cleaning lining. In order to create a wet cleaning device in which the regeneration effect is optimized, in particular while using a minimum of liquid, the wet cleaning device has a decelerating element to assist the removal of liquid and/or of dirt from the cleaning roller, which element has an impact edge directed radially outwards with respect to the roller axis and is arranged between fibers of the cleaning lining during a regeneration operation in such a way that the free ends of the mechanically unloaded fibers project outwards in the radial direction beyond the impact edge.
