The SC400 walk-behind automatic scrubber is designed to bridge the gap between labor-intensive mops and buckets and high-priced, large automatic scrubbers. The SC400 features a 6-gallon solution/recovery tank and is designed for small-area cleaning, including gas stations, schools and healthcare facilities. The SC400 maximizes cleaning productivity with a center-pivot squeegee system. Employing a gas spring for optimal blade pressure, the squeegee system can effectively pick up solution in both forward and reverse in just one pass. The machine also features fully variable solution control settings, which allows operators to clean for over one hour on a single tank.
