Tornado introduces the quiet canister, perfect for day cleaning environments. The TV2 produces less than 70 decibels of sound, making it just right for noise-sensitive environments such as schools, hotels and restaurants. The TV2 also has a multistage filtration system with a built-in high-efficiency particulate air (HEPA) filter to protect indoor air quality. The filter bags are tear-resistant and reduce dust emissions by as much as 70 percent over traditional bags. Finally, the TV2 is light and ergonomically designed, making it easier to use, transport and enjoy.
