WHAT COMBINATION OF WATERLIFT AND C.F.M. RESULTS IN GOOD CLEANING POWER?
Most people know that a person with a body temperature of 105 degrees is sick. They know that they will have to wear a coat if the outside temperature is 30 degrees. People with experience in vacuum cleaning systems know what combination of C.F.M. and waterlift will produce good cleaning power. The best motors on the market have the following specifications. Either of these will produce excellent results. • A two stage, 7.2″ diameter motor with about 120 c.f.m. and 120 inches of waterlift. • Model 9915 with 7.2″ diameter motor with 116 c.f.m. and 120 inches of waterlift. The primary advantage of a three stage motor or model 9915 is that it drives an air driven power brush so that it performs as well as an electric brush. The difference between rotating brushes is their ability to overcome the resistance offered by the carpet. A more powerful motor helps overcome that resistance.
