Query: Not all that

I purchased one of these set it up and... it cleaned maybe TWICE and quit working. It would start the cleaning cycle and begin to move then stopped and went back to start. There is no type of shield or cover for the track area so litter gets into the track and causes problems. At first I thought that was the problem, but after I cleaned it and tried again, it did even less than before. I even called the Litter Maid Company for help. I ended up returning it. Never could figure out why it quit working. Maybe I ended up getting a bad one. Who knows! But if you purchase it, keep your receipt just in case. I have known others to LOVE theirs. By the way, if you have dogs who love getting into the litter box, the cleaning doesn't start until 10 minutes after the cat leaves, if the cat comes back before the 10 minutes, the timer starts over.
