We have both a dyson animal and a hoover wind tunnel. I like both a lot. I waited for a coupon from Kohl's that was 30% off to get the dyson. BB&B also sells them and there are almost always 20% off coupons for there.
we have 2 dogs and 2 cats. our golden retriever sheds A LOT. the Dyson works. it is the best vacuum i've ever used. it's totally worth the money. i've had mine for 5 years and haven't had a single issue. i LOVE it.
Re: Pls recommend a good pet hair vacuum
Dyson Animal. And my last vacuum was a Kirby...
But if you're worried about price, check out the refurbished ones on eBay. I got mine for $100.
