The Shark PowerDetect Clean and Empty (IP3251) system is the ultimate cordless solution for powerful, intelligent, whole-home deep cleaning. It features an Auto-Empty dock that charges and empties your vacuum after every clean, reducing dust exposure by 1000X versus traditional emptying. PowerDetect delivers Shark's most powerful cordless suction along with a redesigned DuoClean Detect nozzle with dirt-detecting intelligence and multi-directional cleaning, for the BEST debris cleaning† of ANY cordless vacuum. While most vacuums push around debris with every back stroke, the redesigned DuoClean Detect nozzle eliminates this problem by capturing more dirt, dust and debris in both forward and reverse. PowerDetect offers an impressive 70-minutes of runtime§ and a MultiFLEX wand for effortless under-furniture reach and flex storage, while Odor Neutralizer Technology guards against bad odors inside your vacuum to help freshen your home. Put it all together and you've got the Shark PowerDetect Clean and Empty system, the powerful and intelligent cleaning solution for your home.
