I have a Kirby G4. As already stated, it's a little expensive, but it's worth it. I've had it for six years now and I think I've had to replace a belt once. I go through a lot of bags though with all the hair. (I have a husky, long haired shepherd, had a rotty, and two cats.) The Kirby still sucks up like it did the day I bought it. It is expensive, but you get a vacuum, a sander, a leaf blower, and a scrubber, (I think that's it) all in one. The one drawback is that it is heavy and with a bad back, it really hurts carrying it up and down stairs, so I just recently bought a Eureka 12 amp. bagless. I ran it in 1/3 of my living room and I had to stop to dump all the hair out. The filter needs cleaned already because of all the hair and coal dust. (Have a coal furnace too). So I'm taking the Eureka upstairs where there's less hair and dirt and keeping the Kirby downstairs. As stated, you get what you pay for. Good luck in your decision.
