Meet the new Shark Cordless Detect Clean & Empty Auto-Empty System Vacuum. It features an ultra-intelligent Detect performance suite~4 deep-cleaning technologies that detect & react to your home to capture hidden dirt on every surface, corner, edge, and crevice. DirtDetect senses the hidden dirt that hides in your home, and automatically boosts power to pull it in. EdgeDetect senses edges and corners and doubles suction* power for more powerful cleaning* (vs. ECO mode). Floor Detect senses carpets and hard floors around your home, and optimizes your vacuum~s performance based on the floor type. Lastly, LightDetect automatically illuminates dark spaces, so you can easily track down hidden dirt. All four of these technologies combine to increase cleaning up to 50%* when carpet and dirt is detected (*Eco vs. Detect Boost (with both Carpet and Dirt), based on ASTM F608). Plus, the QuadClean Multi-Surface brushroll tackles four cleaning targets: fine dust, pet hair, large debris, and dust along edges. After every clean, Detect Clean & Empty Auto-Empty System brings you the ultimate convenience~it empties on its own. Return it to its base, and it charges and empties automatically, sealing in up to 30 days worth of dust & debris, so you can forget about emptying for up to a month, and leave behind the trips to the trash can after every use. Inside the base, Odor Neutralizer Technology guards against bad odors, for a fresh-smelling home. Change the way you clean with the Shark Cordless Detect Pro Auto-Empty System~the dirt-detecting cordless that empties itself.
