The Shark Vertex Powered Lift-Away is Shark's most powerful vacuum, featuring DuoClean PowerFins. While the soft front roller pulls in particles, PowerFins deliver nonstop contact to pick up more in every pass. (vs. original DuoClean) Plus, Powered Lift-Away lets you detach the pod to go under furniture with a motorized nozzle or clean above the floor with a push of a button.
