The CDS 4.8 has been the most popular van-powered system for two decades. It features OverDrive Power Train Technology that takes the hard work out of tough residential and commercial cleaning jobs. Plus, its simple design makes training crew members easy. You get two solution outlets for dual wand capability, three speed settings and a 100 gallon recovery tank for uninterrupted cleaning. Its 14-inch tank footprint also leaves a lot of room for equipment.
