The Rubbermaid FG748018 WaveBrake side press combo high-performance mopping system has a 26-quart (24.6 L) bucket with molded-in wave baffles to reduce splashing, graduated marks for measuring contents, and a side press wringer, tested to exceed 50,000 wringing cycles, that includes a tubular steel arm with a contoured handle for better grip. The bucket and wringer are made from yellow structural web-molded plastic for better strength-to-weight ratio than standard injection-molded plastic. This system can help earn Leadership in Energy and Environmental Design (LEED) credits. This mopping system is suitable for commercial and industrial applications. The bucket rolls on four non-marking casters for mobility, and has a metal wire handle to facilitate lifting and emptying. Combination mop bucket and wringer systems, also called combo mopping systems, consist of a bucket with a wringer (usually removable) that connects to the side or top so that water wrung out of a mop will drain into the bucket. The bucket often has casters for mobility. The wringer can be a simple strainer, used by pushing a wet mop against its walls, or it can have a mechanism operated by an arm that squeezes water out of a wet mop by forcing it against a strainer. Rubbermaid manufactures cleaning, organizing, and material handling products for commercial, medical, and industrial applications. The company, founded in 1933, is headquartered in Huntersville, NC.
