Abstract (en)
[origin: WO2016207077A1] The invention relates to a cleaning device (1), in particular a floor-cleaning device, comprising a cleaning roller (2) for processing a surface to be cleaned, which cleaning roller can be rotated about an axis of rotation (x). Said cleaning roller (2) is designed at least partly as a hollow body (3) having an internal liquid space (4). Said hollow body (3) has at least one hollow body opening (5, 10) for liquid to exit the liquid space (4). In order to devise a cleaning device in which liquid is conveyed from the liquid space to the surface of the hollow body under certain conditions only, the hollow body opening (5) is associated with a force-actuated automatic valve element (6) which, depending on the amount of centrifugal force acting upon the valve element (6) as a result of the rotation of the cleaning roller (2), can be moved to a closing position in which the hollow body opening (5) is closed and/or to an open position in which the hollow body opening (5) is exposed. The valve element (6) is designed to allow liquid to exit the liquid space (4) at a first speed (n1) of the cleaning roller (2) and to block liquid from exiting when the rotational speed increases, i.e. when a second speed (n2) which is higher than the first speed (n1) is reached.
