vacuum

[Janie and Rick Grinstead]

Yup, I vacuum my dog, Lolita (Great Pyr - traveling salesman mix) and 
cat, Jesse (angora fur bag) - our Berner we had, Annabelle would lay on 
her back with all fours in the air so I could vacuum her tummy.
My question - does anyone make an attachment - brush - like or comb-like 
that is meant to use  to get the dead fur  out?
And... if it's made - does it work?  I would like to know.
