In the beginning I loved my shark. It picked up all the crumbs my kids made and lots of cat and dog fur. I used it at least twice a day. After a month of raving about how wonderful it was, the handle broke off. I tried to get a replacement but the part was unavailable. Figuring I just had a case of bad luck, I bought another one. This time I bought the one with the additional side brush. The side brush was certainly not worth the additional ten dollars as it didn't do any better job than the original one without it. After a month and a half of use the handle broke off (in the same place) on the second shark. Great concept but I cannot afford the monthly replacement costs. I guess it wasn't bad luck but poor quality.
