The Treadblaster is our most popular and effective shoe cleaner. The Treadblaster utilizes highly concentrated nozzles to shoot crossing jets of water into the soles of your shoes. The water jets blast the debris out of the treads of your shoes. The Treadblaster typically uses one quart of water per cleaning and has side towers to prevent significant over-spray, keeping your shoes, legs and clothing dry. The Treadblaster requires a standard 3/4" garden hose with pressure of 30-60 PSI and does not require an electrical connection. The unit can be attached to any solid, level surface using the included mounting plate.
