If you take care of it, the Shark Navigator Lift Away (any model) is one of the best bagless uprights out there.
It is the only one rated by Consumer Reports to both clean carpet very well, as well as rate a "very good" at handling - which means it is easier to carry, push and pull than most bagless uprights on the market - including the Hoovers out there.
The Shark Navigator Lift Away weighs only 14 pounds, whereas the Hoovers weigh anywhere from 18 to 22 pounds. But the Hoovers are much better at removing pet hair than the Shark Navigators.
