191. Mop Wringers. There are two kinds of mop wringers to attach to pails. One is made of two flat surfaces which, when pressed together with the mop between (Fig. 105), squeeze the water out of it, and the other is made of two wringer rollers which, when brought together by a lever after the mop is put between them, rotate as the mop is pulled upward and wring out the water (Fig. 106).
