Vacuuming is effortless with a powerful motor. The high-performance and precisely calibrated HiSpin motor ensures thorough cleaning performance with low energy consumption. Good air quality is important, especially for allergy sufferers. The washable UltraAllergy filter removes 99.99% of allergens, fine dust particles, and bacteria, preventing them from being released back into the room with the exhaust air. This results in exhaust air that is cleaner than the indoor air in your home.
