I just recently bought an Eletrolux canister vac that is bagless and with Hepa filter. I have a Great Dane and a Rottie and live on a dirt lane. It is unbelieveable how much dirt and dog hair this thing picks up. I like that the bagless collection part is all washable, with washable filters too. It is wonderful, not cheap $400 but certainly a whole lot better than the Kenmoore canister that I had before it. I also have an Electrolux upright bagless for up in my carpeted bedroom. Again, not cheap, but has all the great filters that the canister vac has. I love them both. I have a little sewing area in my bedroom too, and the upright does a great job of picking up threads.
