ABSTRACT:
A mop wringer for a device for cleaning wet floors has a fixed squeezing plate which is positioned between wringer sidewalls. A movable squeezing plate is pivoted to the sidewalls. An actuating lever is configured as a two-armed lever with a shorter lever arm and a longer arm. The actuating lever is connected to the movable squeezing plate by the shorter lever arm and a push guide. A pressing action is carried out by pivoting the actuating lever away from the movable squeezing plate. In the final pressing position, the push guide forms an almost extended toggle lever joint with the shorter lever arm.
