Abstract
A device for wringing moisture from a mop includes pressure elements between which a holder of the mop, together with a mop cover attached thereto, can be pressed. The mop cover projects beyond the holder, thereby forming a cushion at edges of the holder in order to prevent the holder from doing damage, for example to furniture. In order to be able to wring moisture in a defined manner from both the projecting edge of the mop cover as well as the portion thereof covered by the holder, the two interacting pressure elements form a gap having a height which decreases toward the edges. In particular, the height decreases in a gradual manner. The pressure elements are preferably rollers, several cylinder sections of which can have different diameters in order to be able to obtain gap sections of different heights.
