I also like the Animal because it goes right up against wood trim where lots of the pet dander and hair likes to sneak to hide! :)
I hope this helps. Perhaps Consumer Reports can give you some insight on it however I think personal recommendations are the best!
It can be difficult to decide which is the perfect choice but if we are to sort the number of vacuum, I can personally recommend these vacuum models to be listed as among the best for hardwood floors and a suitable for cleaning pet hair.
You might want to check out the Shark Rotator Powered Lift-Away XL Capacity NV755. It is a bagless vacuum that is tagged to be a top-notch model suitable for hardwood floors.
Or you can also try the Dyson V8. Aside from the Bissell Bolt, a good option as well, Dyson V8 is considered to be the perfect vacuum when it comes to removing pet hair. It is not just the best cordless pet hair vacuum with its' unrivaled battery time it works well with hardwood or even carpet flooring.
Hope these suggestions be of assistance to you.
