The shark rotator lift away is a great vacuum!  I've lived in my apartment a year and I had a smaller shark. When I got the lift away I took it out of the box and it was super easy to put together.  The vacuum feels a bit heavy for me but I think that's because I was just using a smaller vacuum before.  I vacuumed my lament floors and then right to the carpet with no problem.  When I was finished vacuuming I was amazed at how much fur and dirt it picked up! I almost felt like I had never vacuumed in a year!! I would highly recommend this vacuum and I love the feature where I can separate the tank from the unit to do my stairs.
