Littermaid Elite Automatic Cleaning Litter Box Review

I bought this new littermaid elite after adopting a new kitten for my sons 10th birthday, thinking it would prove to be easier for him to take care of his new baby with this product.  (I already have a 13 yr old cat that has always used a traditional hooded litter box)   So far, it does not get all the clumps, it leaves a mess on the rake, if have to scoop after each cat (just not as much) and the plastic waste container always falls off and ends up getting litter (and cat waste) all over the floor. (I recently taped it on to see if that will help)  More to clean up and more often.  It is to shallow and the cats toss litter everywhere, much worse than the traditional litter box I had.  It was $200.00 that has only changed the work I put into it rather than reduced it.  Two thumbs down, wasted money.  I am very disappointed in this product.  I would not recommend this to anyone with cats.  The only up side, is leaving it for the weekend so it scoops "most" of the litter out of the box, but then it just ends up on the floor for me to clean up when I get home.  :(
