I was so excited when i had gotten the Shark rotation Pet lift away ADV upright vacuum, I t was easy to put together, the vacuum is not very heavy which is great. I love that the shark vacuum has the rubber paddles instread of brushes so hair can not get wrapped around the bottle.My favorite  part is that the canister for the dirt lifts away make it super easy to vaccum the stairs and you are not struggling trying yo do it..
