The Rubbermaid Commercial WaveBrake Dual Water Mop Bucket and Side Press Wringer Combo features specially designed WaveBrake baffles to reduce splashing by up to 40% for a safer environment, cleaner floors, and improved productivity. WaveBrake side press wringers provide the flexibility to manage the wetness of the mop according to each cleaning situation. Designed to give users the feel and control that only WaveBrake can deliver, these wringers are 18% more efficient than comparable side press wringers and more durably constructed - tested to last more than 40,000 wringing cycles. The average injection-molded wringer only lasts approximately 860 wringing cycles. An ergonomic tubular steel handle has a comfort grip while the combo glides smoothly on the Quiet Caster dolly. Includes dirty water bucket to separate clean and used/dirty water.
