The Shark POWERDETECT ultra-light corded stick vacuum combines the most powerful suction of any Shark Rocket stick vacuum and intelligence across corded stick vacuums. The new DuoClean Detect nozzle includes Intelli-Sense smart sensors that automatically reacts by boosting brushroll speed when and where you need it most. DuoClean Detect automatically senses different floor types, and 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 DuoClean Detect that will give you the best overall cleaning of any corded stick. 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.
