Rubbermaid Commercial WaveBrake 26/35 QT. Downward Pressure Combination Mop Bucket & Wringer. This mop bucket and wringer combo is made of durable plastic and features 3" non-marring casters for easy mobility. The bucket has a large capacity of 8 gallons, making it ideal for cleaning large areas. The wringer has a downward pressure design that helps to extract more water from the mop, leaving floors drier. The side-press and down-press wringers are designed to last 5-years or 200,000 cycles. Patented WaveBrake baffles result in less splashing, up to 80% versus leading competitors, while mopping and maneuvering.
