This unique shoe cleaner has high force, concentrating nozzles that shoot crossing jets of water into the soles of your shoes, thoroughly cleaning out all Har-Tru in just 5 to 10 seconds. The Treadblaster typically uses one quart of water per cleaning and has side towers that prevent any significant over-spray that could wet shoes, clothing or legs. It doesn’t require any electricity but does need a standard 3/4” garden hose with pressure of 30 to 60 PSI (pressure-reducer valves are available for higher pressures). The unit can be attached to any solid, level surface using the included mounting plate.
