Side-press wringing puts the lever right where a hand naturally falls, which speeds up a long corridor considerably. The bucket is PP, chosen for hardness, high temperature tolerance and chemical resistance, while the rocker and handle are iron and the four 3 inch swivel casters are TPR, gripping without marking the floor. A mop-handle clip holds the mop upright so it does not lurch out while the bucket rolls. A blue sleeve on the rocker prevents slipping during the press. Capacity works out to 26 quarts or 6.5 gallons, and the frame measures 19.5 inches wide, 14 inches deep and 33 inches tall, weighing 10 lbs empty. Schools, restaurants and warehouses all fall inside its range.
