The litter robot scoops automatically after the cat uses it (plus a configurable delay), so it helps with the smell, too. It also has a ton of useless features (eg, it tells you how much your cat weighs each time they poop), but overall it's great. I know it was too expensive, but it has definitely paid for itself in reduced martial friction by removing a shared chore and making the area around the cat box more pleasant
