Estimating the term…
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.
A cleaning device (1), particularly a floor cleaning device, with a cleaning roller (2) that is rotatable about an axis of rotation (x) and serves for treating a surface to be cleaned, wherein the cleaning roller (2) is at least partially realized in the form of a hollow body (3) with an internal liquid chamber (4), and wherein the hollow body (3) features at least one hollow body opening (5) for releasing liquid from the liquid chamber (4), wherein a mechanically actuated valve element (6) is assigned to the hollow body opening (5), wherein said valve element can be displaced into a closing position, in which the hollow body opening (5) is closed, and/or into an opening position, in which the hollow body opening (5) is released, depending on the magnitude of a centrifugal force that acts upon the valve element (6) as a result of a rotation of the cleaning roller (2).
