Received the brown Dyson box from brown, opened it up, vacuum had some wear on the rollers but generally seemed to be in good condition. Put it together and got to work. Whoa! What's that smell?!? Smells kinda like a wet dog. A very strong pet odor. It most likely was coming from the filters. I called Dyson and explained about receiving the refurbished vacuum from Overstock and the horrible pet odor and asked about getting new filters. Dyson rep was not willing to send filters unless I paid retail price for them. I explained that this unit was refurbished and such an odor was unacceptable. The rep suggested I wash the filters in cold water. Ummm, yeah, like cold water is going to remove an odor! Not only that, this machine should have had the filters replaced when it was refurbished at the factory. Dyson rep didn't budge. I said I was going to return the item. Seemed like she could care less. (I didn't indicate I was going to get a replacement). Being a previous Dyson owner, and seeing how well this vacuum worked (in spite of the smell), I called Overstock to inquire about getting a replacement. The O. rep was GREAT! Sales rep had me on the phone all but 2 minutes. In that time she heard my complaint, set up a return with prepaid shipping label, and immediately sent me another vacuum, and didn't even double bill me. Received the second vacuum, put it together and fired it up ... Yea! no odor! Vacuum works like nobody's business! The day before I vacuumed our floors with our old DC17, and this DC41 pulled a surprising amount out of the carpet. This DC41 is suppose to have the most powerful suction of all Dysons. The ball was different compared to the traditional style, but overall is easy to operate. This vacuum is several pounds lighter. The canister is a bit smaller compared to the one on the DC17. Overall, I am very pleased with this purchase and especially Can't say much for Dyson's customer service, but Overstock's came through. So ding one star for Dyson shipping out the first vacuum with such a horrible odor. Other than that, it is a 5-star machine at the price overstock is charing for refurbished (plus $40 internet coupon).
