My husband surprised me with the new swivel Shark this week!  I had just dusted and vacuumed so did not use it until today.  WOW-I could not believe what this vacuum "sucked" up from my carpet.  There are only the two of us and a Shi Suh puppy and we are senior citizens.  My carpet looked like new when I finished vacuuming.  I am very impressed and would definitely recommend this to anyone.
