The new Tennant Model 3090 backpack vacuum cleaner is one of a kind. Its filtration rating, which exceeds HEPA requirements, and its extremely low sound level are unmatched in its class and make it the perfect vacuum for cleaning in noise and air-sensitive environments. The 3090 is perfect for use in retail facilities, schools, office buildings, restaurants and hospitals. This backpack vacuum is also equipped with a two-speed vac motor. Use the low speed for day-time cleaning in noise sensitive areas, and the high speed for cleaning at night. The lightweight aluminum telescopic wand and floor tool allow the user to clean both hard and soft floor with the flip of a switch. (Available in the U.S. and Export Territories only, soon to be CSA approved)
