Greatly reduces smell and there's no more arguing on whose turn it is to clean the litter box. Not to mention scooping poop is just gross. You just put a bag in the bottom, and replace it when it says it's full. To clean the litter box the sphere comes off the base and has no electronics in it so you can clean it with a hose outside. At this point I couldn't go back to a normal litter box, they sell parts to fix it should you ever need to (got mine ~3 years ago and no issues) but even if I couldn't fix it with replacement parts I'd be getting a new one.

Only disadvantages in my mind are, it's a bit bigger than a normal litterbox, it needs to be near into an outlet, and my cat took a bit of time before he liked it.

Overall, this is something that I tell everyone they need if they tell me they have cats.
