Automatic Litterbox Central

Well, I just registered on this site, but a year or so ago I started reading on here for a litter box solution. I have 3 cats, and 3 dogs. The dogs like to get into the litterboxes for kitty-poo snacks, which is maybe the most disgusting thing ever to me. I had 3 litter boxes, two cleanstep booda domes, and a clevercat box. They were working well, but it was such a chore to scoop the three boxes once or twice a day. I decided on a Litter-Robot after reading reviews on here, and overall I've been extremely happy with it. Originially I had just the litter-robot and one other litter box. Recently I bought my first house, and moved out of the apartment, and decided to try to reduce it down to just the litter-robot. That has worked for the cats - they've all used it very well. We just had two little accidents from the cats being in the unfamiliar house - but since then we've been doing great. However, with all three cats exclusively using the litter-robot it is filling up VERY fast, and if we don't empty the drawer empty enough it starts to stink.

Back when I was originally doing my research the other box I was looking closely at was the Cat Genie. At that time however, it only ran either on a timer or at the push of a button. I needed something to clean after each use to keep the dogs from being able to eat out of it. Now I'm interested in it again seeing as how the 120 has Cat Activation - and I wouldn't have to empty a stinky, disgusting drawer every day.
