I had originally had a Dyson and had thought it did a great job, then a Hoover Wind Tunnel and also thought it was very good and now this Shark Rotator Professional Lift-Away blows them away with the cleaning it does.  As soon as I received it I put it to the test.  The dirt bin got filled up very quickly with hidden dirt and carpet started looking refreshed.  After multiple times of using this vacuum throughout the house my carpets now look like they have life to them and the carpet feels very soft to walk on.  I am very impressed with the job this vacuum does.
