The Shark Navigator Pet Pro Upright Vacuum with Self-Cleaning Brushroll is an awesome upgrade to the original Shark I've had for over 10 years. The suction really picks up all the dirt from the floors and the extra large dust container means I only have to empty it when I am done rather than the 3 times I normally have to with the old vacuum. I haven't had the vacuum long but so far the brush roll has been free from hair which has always been an issue for me because the females in the house shed a lot of hair. I love the 12 foot hose and how flexible it is so I can reach up high and in all the places I couldn't get before.
