The Shark Power Detect is the ultimate cordless solution for powerful, intelligent, whole-home deep cleaning. PowerDetect is powered by Shark’s most powerful cordless suction** PLUS a redesigned DuoClean Detect™ nozzle with dirt-detecting intelligence and multi-directional cleaning, making it THE BEST debris cleaning† of ANY cordless vacuum. While most vacuums push around debris in the back-stroke, the redesigned DuoClean Detect nozzle eliminates this problem by capturing moreƚ dirt, dust, and debris in forward AND reverse for faster cleaning§. Power Detect has an impressive 70 min of runtime§§ and a MultiFlex wand for effortless under-furniture reach and flex storage.
