The Rubbermaid Commercial Mechanical Sweeper features a unique, upgraded design with an ergonomic handle; low-profile design that simplifies cleaning around and under furniture; extra-capacity, dual debris canisters with a one-touch release system to help improve productivity; four corner brushes that push dirt and dust from the edges toward the blades; a hood constructed of durable galvanized steel; and two blades and four edge cleaning brushes that provide maximum cleaning power. This sweeper also has non-marking, rubber, sweep blades that effectively pick up dry and semi-liquid debris from wood, tile, vinyl, and carpet flooring; front and back protective bumpers; and a tinted window that allows you to see when the sweeper needs emptying.
