My mother in law passed away late last year and we inherited a Dyson Animal and an Oreck piece of junk that looked unused. After trying both for an honest 3 months, I'd have to rate the Oreck as the worst vacuum I've ever used. On a carpet, my wife couldn't push it at all and I bent the aluminum handle pushing so hard to try to use the thing. It went for $25 at the yard sale.
The Dyson Animal got a longer trial period since we have 2 indoor dogs (thanks to my son and daughter). It's not nearly as bad as the completely useless Oreck, but to be blunt; it's terrible. I even wasted $35 at a local vacuum shop to have it checked out to see if anything was wrong with it. He pretty well confirmed what I experienced, it simply isn't a very good vacuum. He wouldn't even take them in on trade. We got $40 for it at the yard sale.
Seriously, if you even remotely like your Dyson Animal, you owe it to yourself to try any other vacuum (except the Oreck) and compare. The Dyson had less suction, picked up less dog hair and did the worse job going between hardwood/tile floors and carpeted floors than just about any other vacuum I've ever used.
Out of curiosity, I just checked Consumer Reports and read not only the ratings but customer comments. I'm certainly not the only person to think the Oreck XL Platinum (looked up the model) was worthless but the Dyson Animal rated about mid pack of all uprights, which is pretty bad when it costs $600 and vacuums costing $80 rate considerably higher at picking up pet hair! Only the Dyson Ball rated lower at picking up pet hair out of all the vacuums tested. (Yes, the Hoover Tempo Widepath for $80 list rated much higher than the Dyson Animal at picking up pet hair!) I guess that British accent sells. LOL
