    摘要： 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), wherein the cleaning roller (2) is designed at least partially as a liquid-permeable hollow body (3) having an internal liquid space (4), wherein the hollow body (3) has openings (5) for liquid (6) to escape from the liquid space (4) to the surface (7) of the hollow body (3). In order to prevent an undesired escape or dripping of liquid, the cleaning roller (2) according to the invention is designed to block the escape of liquid (6) from the liquid space (4) below a minimum rotational speed (n
    min ) determined by a force balance between a capillary force (F
    K ) and a centrifugal force (F
    Z ) acting on the liquid and the escape of liquid (6) from the liquid space (4) is allowed once the minimum rotational speed (n
    min ) has been reached.

    摘要： We provide an agitator assembly for use in a cleaning apparatus, the assembly including: an agitator comprising a body with a first and a second end, and a first alignment formation at or adjacent the first end and a user-graspable member at the second end, the user-graspable member being rotatable relative to the body; and a drive member operable to impart rotation about a drive axis, and providing a second alignment formation adapted to cooperate with the first alignment formation; wherein relative axial movement of the agitator in a direction towards the drive member causes contact between the first and second alignment formations; further relative axial movement of the agitator in the same direction causes relative rotation between the agitator and drive member, and relative rotation between the body and the user-graspable member of the agitator.
