The rag wringer is a device or hand tool with which you can easily wring out a mop.
One model is a perforated metal container (approx. 20 cm wide; approx. 35 cm high) with a handle that can be hung over the edge of a bucket. The wet mop is put in and the lever is pushed down; two sturdy plastic parts now move down and squeeze the water out of the mop. [MOT]
