I've had this product for less than 6 months, after only 3 months the bristles stopped spinning. I thought this was strange since there is only a small part of my house with carpet, so this vacuum wasn't used much. I replaced the blet and the vacuum ran normally for about 2.5 months and the bristles stopped spinning again. I ordered a 4 pack of belts since this seems like it is going to be a regular thing. Changing the belt did not help this time so I thought maybe I got faulty belts or possibly the wrong size, so I ordered more belts paying close attention to every detail of the order. After putting on the new belts, the brissles spin erratically and stop completely when applied to the carpet. If you are looking for a product that will last any amount of time, this is NOT the product for you. Don't waste you money.
