Its flushable, cheaper, requires less frequent cleanings, and I guarantee to you, if you were using the feline pine, if the litterbox wasn't cleaned for 4 days, you'd barely notice. Our larger cat is also VERY fastidious, if he or his brother had used the box previously, he'd poop on the floor right in front of the box. This stuff hides odor so well that the problem went away entirely. Even if the litterbox hasn't been scooped for 3-4 days (we got called unexpectedly out of town), he goes in the box, not on the floor.
My biggest problem with the auto-cleaning ones (and we had a littermaid) was that we'd forget to clean out the disposable bucket for a day or two, and it would get so full that there'd be clumps spilling over the sides, and usually onto the floor. And then when you pick up the disposable part, its covered in litter and ickiness.
Oh, and if your cat pees a lot at a time, it might jam trying to lift the clump because it'd be really heavy. Then you get to hear it whirring, backing up and trying again, for about 10 minutes before auto-shutting off. In the middle of the litterbox.
Our cats also kick litter to one side of the box, leaving the other side empty. That jams it too, so we'd again be stuck with the little rake thing, auto shut off because it thought there was a jam, right in the middle of the box. And then the cats wouldn't use the box.
Can you tell I didn't have a good experience?
The only drawback that I've found to the feline pine is that it tracks a bit. But for our cats, it doesn't track any more than the clay litters we used previously, and the tracked stuff is essentially sawdust, so it vacuums a lot easier than a clay pellet.
