The Shark DETECT Lift-Away corded upright vacuum combines powerful suction with cutting-edge Detect Technology for an ultra-powerful clean. The new Detect nozzle with Shark’s Intelli-Sense smart sensor automatically reacts to floor types by boosting brushroll speed when and where you need it most. Floor Detect automatically senses different floor types, and Direction Detect even senses the direction you are vacuuming, directing powerful suction either forward or in reverse. Dirt, debris, large piles, fine dust, and pet hair are no match for Detect. For above-floor cleaning, Lift-Away technology means you can detach the pod to take your cleaning to stairs, furniture, windowsills, and more. Shark’s Odor Neutralizer Technology guards against bad odors inside your vacuum to help freshen your home. Plus, Anti-Allergen Complete Seal with HEPA filtration seals and traps 99.99% of dust, dander, and allergens inside the vacuum, keeping them out of the air you breathe. Based on ASTM F1977, down to 0.3 microns. Allergens refers to non-living matters.
