The Shark Navigator Pet Pro Vacuum works great if you have a pet that sheds.  My daughter vacuumed my bedroom with our old vacuum the day before the Shark arrived.  The next day she vacuumed my bedroom with the Shark, the canister was full with dog hair.  That is how much suction this vacuum has.  The swivel head makes it easier to get under end tables and beds.  I love that I can adjust the suction to the type of floor I am vacuuming.  I love my Shark.
