Quoted from toyotaboy:
Dyson... I hated that smug british guy (It took me 700 prototypes to get it right). Got tired of crappy vacuums, ended up with a $1200 Kirby. Built like a tank, but then brushes started getting noisy. Then a few strands of hair got caught up in the entry and because it spins so fast the hairs acted like a weed wacker and tore a hole in the hose. Fed up, I saw a Dyson canister vaccuum on woot.com for $299. Figured I'd give it a try, it works flawlessly, cleans well, easy to clean, built tough. So then I started seeing those fans on woot, the ones with the cooler / heater. Bought one for $199, again loved it so much bought a second (one for bedroom, one for living room). It's efficient, quiet, easy to clean (wipe the blade, blow out the intake holes of dust).
I'm a believer! I bought a refurbed DC41 Animal for $200. First thing I did was vacuumed the living room and hallway with the existing vacuum. Then went over it again with the Dyson. I'm a weirdo. I was so impressed I texted a picture of the results to my girlfriend at the time.
