and I really like it. With 20% off coupon it was really reasonable, and I actually like it better than my Dyson. The dust cup is smaller, but so is the head, so it fits in a lot more places (under furniture, etc.). I think it does a better job on bare floors than the Dyson did. We still have our Dyson Animal, but it doesn't work on berber, so it's relegated to the plush carpet upstairs. When we get rid of that carpet, the Dyson will go too. I will not buy another one.
I use the Shark on laminate, tile, and berber carpet.
Return it to Costco and get another Dyson. You must have gotten a lemmon b/c we have the first Dyson that ever came out (purchased it in 2006 or 2007) and it is still working perfectly!
I'm have the Shark Navigator Lift-Away, I like it. It's smaller than a normal vacuum, which is actually kind of nice because it gets in tighter spaces and underneath some of our furniture.
