Abstract

A wet cleaning device, has a cleaning roller that is rotatable about a roller axis, the cleaning roller having a cleaning covering. The wet cleaning device has a deceleration element and a guide element for supporting the removal and discharge of liquid and/or dirt from the cleaning roller to a liquid channel. The deceleration element has an impact edge in opposite direction to the fibers of the rotating cleaning covering, wherein the guide element is arranged in the direction of rotation of the cleaning roller behind the impact edge. During a regeneration operation of the wet cleaning device, the impact edge is arranged so far apart between the fibers of the cleaning covering that free ends of the fibers project outward in the radial direction beyond the impact edge, and in the event of an impact on the impact edge, are deflected in the direction of the guide element.
