I have a Litter Robot (that’s the actual brand name) and it’s worth the money. Completely eliminates smell other than right when they do the deed. Incredibly easy and clean to empty, but that’s all besides the point. They ha e the BEST customer service ever. I’ve had parts replaced for free, experts on the phone guide me step by step on how to fix it if it malfunctions, and once they even replaced the entire dome for free (plus shipping). I’ve had this for several years and it’s amazing. Truly.

I’ve had other automatic litter boxes too but none of them have been as durable, clean smelling, or easy to use as this. Plus I get phone notifications when it’s full and it won’t cycle anymore so I can change it.

My cats took a week to get used to it but now they love it. They offer their own litter but you can buy your own as well. There are certain restrictions on litter type though, check that out before you buy litter.

It separates the waste well, and there is hardly any wasted clean litter in the waste bag when I take it out.

And it actually stinks LESS than a regular box because of how it stores the waste and the fact that it seals it away a few minutes after cats go, using a weight sensor to tell when a cat has left the box.

Edit: reading this sounds like an advertisement, but I swear I’m just a dude who loves my litter box a whole lot.

Bit expensive and you need to connect to water and a drain. Either toilet or near washing machine works.

It worked for us for about 4 years. Works very well and washes the litter each use.
