Like many other people, I was skeptical about spending a few hundred on one single vacuum cleaner. It's how much? Does it also cook me dinner? Well now this vacuum doesn't cook, but it CLEANS. I have owned MANY vacuums over my adolescent and adult life. Hoover/Electrolux/Dirt Devil, etc. With the exception of my giant shopvac, none of them have had the suction power I desired, that is until I threw caution to the wind (and my credit card statement) and bought a DYSON. After reading all the positive reviews on overstock for a refurbished dyson 41 animal model, I couldn't say no. I ordered it and waited, reading over the reviews where some people had one that was used heavily, to one that wasn't used at all. My vacuum arrived and looked brand new. Everything was packaged neatly, and very very clean. The filter even looked brand new. I was able to assemble it in less than 5 minutes ( I do have a decent assembly background) but I think anyone could put it together easily. I fired it up and made a pass over the hallway carpet that I had previously gone over with my Hoover PAWS system, and the Dyson DC41 Animal's canister was almost FULL. It looked like I hadn't vacuumed in a month. GROSS. I have three dogs, and I am now confident that I have a vacuum that can handle all they can dish out, I've already accumulated enough hair from vacuuming the hallway to make another dog. This thing is also quiet! I'm use to power and noise, and this thing has the power, but the noise is not at all what I expected. Thank You Dyson & Overstock.com I'm sorry it took me so long to buy one of your wonderful vacuums. Never will I stray again.
