‘Rubbermaid’s Bucket and Wringer Combo has holes in two wringer plates, so more water is forced from the mop faster, making it a more efficient accessory to fit any light janitorial needs. This mop bucket has a reverse-wringing mechanism for more comfortable use. Built-in lift handles on the bottom of the bucket make lifting and emptying easier. 3″ casters move smoothly as you guide the bucket. The large 31 qt. capacity improves productivity by reducing the frequency of trips empty dirty water. Can be used with up to a 24 oz. mop.
