Hey K.,
I feel 'ya... I went through 2 swiffer vacs myself before I realized that rechargable was just NOT the way to go. My mom then gave me a Eureka stick broom vac that worked great, but emptying the dust cup caused such a mess and the built-in filter was completely unable to be cleaned and became totally clogged once you use the vac the first time (ridiculous design), so that too went out in the yard sale. I finally settled on an Oreck canister vac (the one you see advertised that "picks up an 8 pound bowling ball". They are expensive, but I wound up finding mine on Craigslist, and you could probably do the same. If not, I'm sure you could negotiate a good deal on a new one, since the stores operate as independent franchises and the salesmen are probably dying to make a sale right now in this financial climate. Anyway, I couldn't be happier with it. It's SUPER powerful, has an extending hose with sweeper attachment, lightweight (carries comfortably on your shoulder while you use it) and has a bag and replaceable hepa filter just like a real vacuum. Oreck also services them for you for free and they have a very long (like 20 years or something) warranty, which Oreck is standing by even though I bought mine used. Our house is all hardwood and tile, and we couldn't live without this thing to clean up after our two dogs and two boys. There is an Oreck store in Vienna --you can go there to "test drive" them (that's where I take mine for service and cleanings), but like I said, you might want to check online or Craigslist too.
