I have the Litter Robot.
Very reliable, very powerful motor etc. Does NOT jamb. Does smell and the storage tray is small as othrs have said...
BUT THE BIGGEST PROBLEM:
The LR rotates to clean the litter, making the whole inside of the LR contaminated with dirty litter.
I have one cat that will get in and stick his head out the entrence hole, he has no problem with the LR, but my other cat likes to stay completly inside and it is NASTY in there!
So now she decided to just piss on the floor instead, returning to my old hand strained LB cured the problem for her.
The LR is the best designed automated cleaner with a major flaw, it is extremly dirty, and needs to be thouroghly cleaned at a car wash once a week, a pain that makes the LR useless for many cats! (and as most know cleaning clumping litter is a nightmare)
So if you have a finicky cat, save your money.
