This product is so bad. I bought one and first thing out of the box it didn't work. So I returned it and got another one. And the second one did an amazing job... for about two months then it stopped working. I had trouble with the machine saying the brush roll wasn't in there right. After attempting to fix it probably 5 times. It would finally work. But now it is stuck in self clean mode. And I cannot use the product. From the get go on the second one the boost mode never worked. So again I do NOT recommend. It's a waste of money.
