I have both a Dyson Animal and a Shark Navigator Professional Lift-Away. I think the Shark Navigator cleans at least as well as the Dyson (and maybe better), is easier to use, and is a better value. I got both at Costco. I have come to think the Dyson is over-priced compared to the Shark. I used to be pretty happy with the Dyson, but over time, I've slowly become less enchanted. It works and does what it's supposed to--I'm just not convinced it's worth the extra money, having used the Shark.
I use both on a combination of hardwood floors and rugs, in a multi-dog home where we have A LOT of fur. I have 3-4 GSDs in the home at minimum, depending on my foster dog situation. It takes us about 3 full canisters of fur to completely clean the floors. My dogs' fur defeated an older generation of Roomba. I've been "fired" as a client by at least one cleaning lady over the amount of shedding during blow-out season -- I mention that to convey my vacuums have to work hard. We're not playing here when we say it has to handle dog hair!
The one important thing with any vac on hardwoods is to remember to TURN OFF the rotary beater so that it doesn't scratch the floor with embedded dirt. Periodically pulse it on to force the dog hair through when collecting large clumps of it.
Dysons seem to me to be not all that well made, have plastic parts that break over time (one cleaning lady has caused the plastic pedal to lean it back to get screwed up -- we could fix it with a screwdriver, but still!). I haven't had the Shark as long as the Dyson, so it hasn't been subjected to the years of use (and abuse) yet.
I hate the hose on the Dyson. It's badly designed, too short, and just awful to use. The Shark is much easier to use to dust blinds or pull fur off a sofa.
If you belong to Costco, get a Shark there, use it and if you hate it return it because that's perfectly fine under their return policy. I think you'll be glad to have saved several hundred bucks over the Dyson.
