Query: Not so Great Littermaid :(

I thought the newest and fanciest Littermaid would be the bomb .. oh yeah it bombed all right. The litter area is WAY TOO small for a cat of 10 lbs or more and they end up peeing on the circuit board and shorting the unit out. I went through 3 of these (Littermaid replaced them for free)Littermaids in under 1 month. In the end, I went back to the other older version as the litter area on those is MUCH bigger.
