I got this product and it worke wonderfully...for a whole 5 steps. then the brushes stopped turning, even though there is no blockage or anything wrong that I could tell. I dismantled the item and made sure it was clean and clear but it doesnt work any longer.If you buy this, make sure you have a good return policy. Unfortunately I bought it from a third party seller, not direct from amazon, and that option would cost me almost as much as the item itself after shipping to me and from me.Im chalking it up to a loss, but thought I would warn you.
