With the new Cascade 20 you can clean 8,000 square feet in one hour without stopping to refill compared to 3,800* from the competition with one or two dumps and refills. Not only does the Cascade 20 clean more square feet per hour than other mid-sized extractors, it also removes more soil from the carpet. At 400 p.s.i. and 1.3 gallons per minute, soil is flushed from the carpet fibers. The new Cascade 20 will increase your productivity so you can clean more carpet in less time!
