The Cascade 20 is the ultimate in productivity combined with CFR’s unique cleaning technology. Not only does it clean more square feet per hour than any other mid-size extractor, it also removes more soil from the carpet. With a run time of over an hour between refills, the Cascade 20 has a productivity rating of 8,000 square feet per hour. All other mid-size extractors pale in comparison, refilling their tanks once, twice or more. CFR’s 20 gallon system out performs units twice its size. The Cascade 20 is available as a self contained work station or in a Pro version both for use with wand and hand tools.
