Rubbermaid FGQ93000BLUE 896 Oz mop bucket. This mop bucket is made of durable plastic with a smooth, non-porous surface that helps prevent bacterial growth and cleans up easily. Its spacious design has a 896 Oz maximum capacity that accommodates mop pads up to 18"L. This mop bucket features a washboard surface that helps to remove dirt and debris from mop pads before wringing. It even has a convenient snap holder that secures your mop handle for safe, efficient storage.
