The Shark PowerDetect Pet Plus Clean & Empty cordless stick vacuum and auto-empty system is designed for powerful, intelligent, whole-home deep cleaning. It features an Auto-Empty system that charges and empties your vacuum after every clean and holds up to 45 days of dirt and debris, so you can tackle carpet and hard floor without stopping to empty the bin. Powered by Shark's most powerful cordless suction*, PowerDetect uses a redesigned DuoClean Detect nozzle with dirt-detecting intelligence and direction detect technology to deliver the best debris cleaning of any cordless vacuum** by capturing more dirt, dust, and debris***. As you move through your home, 4X intelligent technologies detect hidden dirt, edges and corners, carpets and floors, and cleaning direction, then automatically boost power when dirt and debris are detected. Unlike most vacuums, clean on both forward and reverse passes. With an impressive 70 minutes of runtime**** and a MultiFlex wand for effortless under-furniture reach and flex storage, you get cordless convenience with deep cleaning performance for homes with pets.
