Abstract

See full text

A cleaning device has a cleaning roller that is rotatable about an axis of rotation and serves for treating a surface to be cleaned. The cleaning roller is in the form of a hollow body with an internal liquid chamber, and at least one hollow body opening for releasing liquid from the liquid chamber. In order to develop a cleaning device, in which liquid is only released from the liquid chamber to the surface of the hollow body under certain conditions, a mechanically actuated valve element is assigned to the hollow body opening, wherein the valve element can be displaced into a closing position, in which the hollow body opening is closed, and/or into an opening position, in which the hollow body opening is released, depending on the magnitude of a centrifugal force that acts upon the valve element as a result of a rotation of the cleaning roller.
