The invention relates to a torsion wringer, comprising a contraction device (1) for receiving a wiping head of a mop, wherein the contraction device (1) has an upper part (2) and a lower bottom (3), which are connected to one another by way of contraction lamellae (4). The contraction lamellae (4) are designed and/or articulated at the upper part (2) and the bottom (3) such that the upper part (2) is rotatable relative to the bottom (3), wherein along a travel path (H), the contraction device (1) is movable relative to a carrier device (5), as a result of which the upper part (2) rotates at an angle of rotation (T) relative to the carrier device (5) and relative to the bottom (3). In view of the object of the invention to design and further develop a torsion wringer of the aforementioned type such that the torsion wringer is cost-effective, wherein with a short travel path of the wiper head of the mop, the torsion wringer can be effectively freed of liquid, wherein a large rotational angle can be achieved without entanglement and self-locking of the upper part of the contraction device, and wherein the torsion wringer is of low overall height, the invention is characterized in that reduction means are provided, by way of which a force that counteracts the rotation of the upper part (2), can be reduced.
