Meet the cordless vacuum that empties itself, so you don’t have to. Forget about emptying for weeks at a time. Every time you finish cleaning, Shark Clean & Empty automatically deposits the dirt into a completely sealed base unit that holds dirt and debris for up to 30 days. No more manual emptying after every clean – simply return the vacuum to the dock and let the hands-free Auto-Empty System empty the cordless vacuum’s dust-cup into a large bagless base. Seals away dust & debris. Inside the base, fine dust particles are sealed away after every clean – perfect for homes with pets or allergies. Anti-Allergen Complete Seal captures and traps up to 99.9%* of dust, allergens and irritants inside the base*, keeping them out of the air you breathe.
