Powerful cordless cleaning, without the mess. Meet Shark Clean & Empty, a lightweight cordless stick vacuum that auto-empties after every clean into a sealed, bagless base, so you can skip manual emptying. HyperVelocity suction handles dust, debris and pet hair across floor types, while Anti Hair Wrap helps prevent tangles for smoother cleaning. A sealed HEPA system captures 99.9% of dust and allergens, and the auto-charging dock ensures your vacuum is always ready to go.
