Pros: The idea is great.
Cons: The actual implementation is HORRIBLE.
The machine is a GREAT idea. Cat litter is disgusting.
The idea of this machine is GREAT.
That stated, the machine does not work. The machine has stopped working numerous times. Most recently, my wife cleaned out the drain tube Tuesday of this week and now Friday it is not draining again.
Cleaning it to get it work is absolutely disgusting. It makes cleaning normal litter boxes seem like heading to the candy store.
The complexity of the actual mechanisms within this product are made of plastic and we have had the rotation mechanism break twice.
