The best purchase I have ever made for my cat was using the expensive crystal litter. It costs way more than the cheap cardboard pellet one you can buy, but each crystal contains some kind of scent and really, I clean it once a day and it never smells that bad. They make a big mess if you don't put a mat beneath the tray though and get tracked through the house like tiny granules of sugar.
I have considered a robot litter box, but seems to me, the cost far outweighs the benefit of not having to change the litter yourself very quickly. These things are pricey and based on what I've read in this post and tonnes of reviews online, they're not particularly that great.

expensive or not, getting correct litter is the key. And the mat of course. And feeding good food to your cat - that would significantly take care about smell, consistency, frequency and other important characteristics of the output product, not even mentioning overall health and well being of the cat.
