OH MY LORD! I saw something in action this weekend that we all need. I don't even have the dog yet, and I'm thinking, "I need to buy that!"
It's the Pet Buddy Hair Vacuum thing that's on the infomercials. I was at a family St. Pat's thing this weekend (yes, I come from a large family of Scots-Irish drunks) and Kristy had one of these things.
It's SO COOL.
If you haven't seen the infomercial, it hooks up to a normal vacuum, like an attachment. You put the vacuum and the hair catching tub in another room, and there's a long, long hose that you take the dog or the cat or whoever to be brushed a room or two away--we went out to the patio. The end of the hose has little grooming teeth on the end of it, and you just use that to brush your animal, and it sucks up all the hair as it loosens!
Obviously, it doesn't do as good a job as real tools do, but it did a really credible job of getting the surface loose fur, which meant that it was much less messy when she broke out the heavy-duty tools. Plus, as she got little piles with the tools, she just sucked them into the vacuum!
The cats loved it even more than the dogs did. I guess the sucking sensation of the vacuum hose was quite pleasant!
Most people brought their furkids, so we did 9 pr 10 cats and probably 8 dogs. The kids had a BLAST vacuuming their animals.

It's one of the funner things we've come up with for the kids to do at these family things in ages!
