Bests & Worsts Reviews from Amazon

This damned thing ran great....one time. The next time I tried to use it, it was for about 10 minutes, then the main motor shut off. I thought well it should not overheat in 10 minutes, but I waited a day or 2 and tried again. It ran for about 90 seconds and shut off. Update: I finally convinced Shark to send a replacement vacuum. It took a fight and calling every day for weeks. But, the new vacuum is no better. It runs a few minutes, then shuts off. It takes a whole day to vacuum my living room. And frustrates me beyond belief. I think it is caused by that second brush, which I was so excited about. Something causes the motor to overheat without anything ever even being sucked up. JUNK
