Designed to boost suction power right where it's needed, this powerful vacuum cleaner uses advanced detection technology to get the job done. The stick vacuum uses a DuoClean Detect nozzle with IntelliSense smart sensors to increase suction and adjust roller speed along wall edges and in different directions. It also identifies and adjusts to floor type. The self-cleaning nozzle grips and captures even more debris, dirt and hair, and an odor neutralizer keeps bad odors from developing inside the machine. Plus fine particles and allergens are trapped as you clean thanks to a special seal with HEPA filtration. POWERDETECT delivers Shark's most powerful suction, paired with a redesigned DuoClean Detect nozzle featuring dirt-detecting intelligence and direction detect technology for superior debris pickup. Unlike traditional vacuums that push debris backward, the DuoClean Detect nozzle captures more dirt, dust, and debris in both forward and reverse motions for faster, more efficient cleaning.
