And...they have a new "lip" attachment for the Litter Robot, that catches the "edge peers" if they hang over the opening- I am so excited, since I have one of those (grrrr), and have been using paint bucket pour lids cut in half to do that, lol. They also have a ramp now, and a few other things, plus you can buy replacement parts from them right off the website after the warranty expires

.
And yep, no special litter, no special trays, bags, etc., only plastic kitchen garbage bags and scoopable litter (I haven't tried the crystals, but that is a great idea for the drawer!).
And you don't have to leave it on all the time either- you can turn it off, and flip the switch a couple of times a day to clean it (I did this when mine were learning to use it).
When I looked at some of the others, the special trays, etc. were kinda adding up, even though the other boxes were initially cheaper. Plus, push a button, fill it, push a button, dump the whole thing, sick cat makes a mess- take the dome out in the yard and hose it out...so cool, lol. Having a full dome is really nice!
They also have an 18 month warranty (which my sister had to use, and wow, their customer service is great!!!), and a 60 day "you and your cat will love it" guarrantee, where you can return if your cat doesn't like it.
So, yeah, I kinda like mine
