I have a shark navigator lift away = have had it for a few years now and STILL love it. I have 2 shelties, bunnies and birds so vacuum quite frequently. It does better picking up the hair than the $1600 Kirby that the salespeople brought to my house to try and sell me.
It's as easy to use as the commercials show - I love that I can take the canister off the foot and vacuum up high. It's very lightweight and easy to use that way. Sheltie hair ends up getting on the tops of my curtains/rods so I have to get up there a few times a year LOL.
Their customer service is great too - had an issue with the beater foot crapping out on me. I was going to buy a replacement (I forgot to send in the warrenty card) but they sent me one at no charge, not even shipping. That was a $60 part !
I bought a used Kirby on Craigslist. It was only 2 years old and I paid $60 for it. This thing is a beast! I have sucked up pennies into it and it folded them like taco shells. Plus it has the carpet shampoo attachments. I can send it out to be refurbished instead of replacing it. It will last me forever. It's heavy but that's part of it's appeal for me. I'm not going to be able to break this thing.
I have a Dirt Devil Breeze that has worked pretty well, especially considering it was $50 or less. I thought I killed it when I vacuumed my sewing room and sucked a long skinny scrap of fabric. After I took it apart, all the way apart, it worked better than before.
For my hardwood/laminate floors, I have a DD Versa that I got for $9. It works great on the smooth floors; I would like to change the cord to a longer one so I can do the whole floor w/o unplugging.
We had a Shark and it worked fine, though not great, for the apartment we were in a few years ago. We noticed our bedroom constantly smelled like our beagle, though, and the Shark really wasn't cutting it for all the dog hair, so we decided to buy a Dyson with BBB gift cards we received from our wedding. We really love our Dyson - works great on the stinky beagle hair, my hair, dirt/hay/horse hair I treck in from the barn. Our carpet is thick, so the Dyson is a necessity for us, though I am very thankful the hubby is agreeable to do the vacuuming for the house. I have thought about getting another Shark and keeping it for the hardwoods only as an easier, smaller vacuum to use.
