The wringer is movable over a range of travel between a mopping position and a range of wringing positions, in which wringing positions the wringing sleeve covers and compresses at least a portion of the mop to thereby expel liquid from the mop. The wringer is rotatable relative to the shaft through at least a portion of the axial range of travel. The wringer further comprises at least one volute wherein the volute defines a semi-enclosed area inside the wringer, the semi-enclosed area configured to receive a portion of the mop through a gap defined in the volute. The volute includes a first fin and a second fin that define the gap therebetween.
