Large Capacity Bucket It’s recommended to only fill mop buckets 2/3 of the way full to prevent dirty water from overflowing when a mop is placed in the bucket. With this 35 qt. capacity, you’ll have enough room to mix water and cleaning solution without having to go back and forth for more water in between mopping the same area. Removable Wringer With the wringer attachment placed above the bucket, you can effortlessly wring out mops without the bending and pulling required on other mop buckets. For added convenience, this wringer can be removed prior to emptying the bucket for an easier lift.
