This is the new Shark Rotator Powered Lift-Away Speed with DuoClean Technology (model NV801). It sports both Lift Away Technology and DuoClean Technology. Having 2 brushrolls may seem a little odd but it works well. Pickup on carpet and bare floors is very good, as is the machine's ability to rid your house of pet hair. We also like the maneuverability of the machine and the easy maintenance.
