... litter units we have tried (and we have tried pretty much all of them) you will be replacing it ...
Although this is one of the cheaper automated cat litter units we have tried (and we have tried pretty much all of them) you will be replacing it pretty much yearly - the motor to make the tray travel will wear and it will stop cleaning. That said, for the price and convenience, I am now on my third unit is as many years simply because it is the most reliable and easy to clean compared to the others that I have spent much more on! BTW, I have two adult cats and they are unfazed by it and actually watch the motion when it cleans after them!
