Very cheaply made. I've had two of these in less than 5 years. The first one that came with the original vacuum system was installed by our builder and the head only lasted about 2 years, the engine died from it. So I bought a new one here at Revain. Now, less than 3 years later, this one is broken. I've cleaned it, replaced the belt and brush, but I still can't get the brush to spin. Right now it's only good for sticks. I can no longer use the brush on my carpet because I refuse to buy another piece of junk like this.
