I was originally excited to purchase the Litter Maid. However, my excitement turned to frustration and anger mere minutes after I unboxed the litter box. The first time it scooped the cat droppings out fine. After that all the machine would do is run constantly. I finally had to unplug the litter box, remove almost all of the litter and try again. Still the machine would not work. I finally after 1 week of owning it, threw it in the garbage. I WILL NEVER buy another automated litter box from this company.
