Meet the Shark Vertex® Cordless Vacuum, WZ440H. It delivers powerful suction, plus the go-anywhere convenience of a lightweight cordless stick vacuum. For every surface, Vertex® features DuoClean® PowerFins™. This deep-cleaning nozzle technology gives you continuous contact with all surfaces, digging deep into carpets, directly engaging hard floors, and picking up more dirt in every pass (vs. original DuoClean® ). Plus, Vertex® is equipped with a self-cleaning brushroll, for powerful pet hair pickup with no hair wrap. For above-floor cleaning, a removable hand vac detaches in seconds so you can take on furniture, stairs, and more. MultiFLEX® technology allows you to bend the wand to clean under furniture, or fold it over for compact, freestanding storage. With one long-lasting battery, you can get up to 50 minutes of runtime. And when you’re done cleaning, an XL-capacity dust cup holds large amounts of debris, and empties with the CleanTouch® Dirt Ejector, so you never get your hands dirty.
