Which Litter-Robot is right for your cats?

I own four cats and have bought every generation of these since the LR3. Answer four questions and I will tell you which one I would actually put in your house, including when the answer is do not buy the expensive one.

What is scooping actually costing you?

Everyone stares at the sticker price. Nobody prices the five years of their own life spent bent over a litter box.

Straight math: minutes x 365 x 5 divided by 60, times your hourly rate, against the purchase price. Litter spend is roughly a wash between the two, so it is left out rather than fudged in my favour.
