When you think about vacuums the common names that come to mind are either Eureka or Electrolux. Both manufacturers produce consumer and commercial models. The commercial models are the Sanitaire vacuum line which features upright vacuums, backpack vacuums, multi surface vacuums, and have now even expanded into floor machines and carpet extractors. Some of these models include the SC series, the Tradition, Drytime air mover, Transport backpack vacuum, the Restore carpet extractor, the Cast floor machine, and the Cast burnisher buffer. On the higher side as far as pricing vacuums include the Eon and the Force series. Sanitaire is a well-known vacuum in the cleaning industry because of their durability against water damage in the way they are constructed. Most commercial vacuums suck the air and at times water up through the bag into the vacuum motor which prematurely destroys the motor. Sanitaire have come out with a system that utilizes an impeller to move the debris from the floor into the back avoiding moisture going through the motor.
