I've been using my Shark Navigator Swivel Pro Complete Upright Vacuum for about a week now. It is the best vacuum I've ever used capable of successfully sucking up those dreaded doggie hairs. This machine has a super powerful suction that truly gets the job done. I especially appreciate that the HEPA filter is washable and reusable. The dirt cup is enormous which makes the job easier in that I don't have to stop to keep emptying out the cup in order to complete my vacuum chore. It's a little heavier than vacuums I have used in the past, but it is doable. The cord is nice and long, which can reach across long areas without having to be unplugged and replugged in. Another really nice feature is that the accessory tools can be stored directly on the vacuum, so that they are always handy, when needed. I have been a fan of Shark for many years, and they still amaze me!
