Automatic Litterbox Central

I got my ScoopFree yesterday and everything seemed to work fine until it got dark. The green light would flash as to indicate an object in the box when there was nothing in the box. When I turned on the light, the green light went steady. I called ScoopFree and they said this problem has been reported before, and there may have been a bad batch of ScoopFrees. They are sending me a new one free of charge, and even paying for shipping.

If anyone has this problem, make sure to call the company. They are trying to recall all the bad ScoopFrees.
