Mop Bucket: This bucket and wringer combination set is molded from 100% polypropylene and is extremely tough. Don't settle for a lower-quality plastic that will crack and break with regular use. This bucket can hold up to 32 quarts of water or cleaning solution, and the side press wringer provides plenty of space for the biggest of mop heads for maximum versatility with your cleaning tools. 3" non-marking casters push into the sleeve to keep them locked in, so you never have to worry about losing a wheel. The bright yellow color and identifiers on both sides make this bucket the perfect option for commercial use.
