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.

A cleaning machine may include: a drive shaft; a rotation transmitting mechanism configured to transmit rotation of the drive shaft; a brush attaching member configured to rotate about a rotation axis; a clutch mechanism coupling the rotation transmitting mechanism with the brush attaching member; a brush attached to the brush attaching member; and a brush moving mechanism configured to move the brush attaching member between an adjacent position adjacent to a working plane and a distant position distanced from the working plane. The clutch mechanism may be configured to transmit the rotation from the rotation transmitting mechanism to the brush attaching member when the brush attaching member is at the adjacent position and cut off transmission of the rotation from the rotation transmitting mechanism to the brush attaching member when the brush attaching member is at the distant position.

The present disclosure provides a surface cleaning apparatus that includes a housing including a base adapted for movement across a surface to be cleaned, a fluid delivery system, and a recovery system. The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft surfaces, and for different cleaning modes, including wet cleaning, dry vacuum cleaning, and self-cleaning. Methods for self-cleaning a surface cleaning apparatus are also provided.
