If you have average-sized cats, up to 18 lbs, and prioritize comprehensive safety, the MW-SC01 is for you. Its 10 high-precision sensors offer enhanced protection. You'll appreciate remote app control for cleaning and tracking cat weight and activity data, all in a relatively quiet 40dB operation. This model suits users with a stable 2.4GHz Wi-Fi connection, seeking smart features and peace of mind for their feline friends in a more compact footprint, despite the slightly higher price.

If you own large cats, multiple felines, or senior/short-legged pets, the MW-SC02 is ideal. Its 75L extra-large interior and 22 lbs max pet weight capacity cater to bigger breeds. The low 6.8-inch entry ensures easy access, while 9 safety sensors keep pets secure. Odor control is a priority with its sealed waste door and 8.0L capacity. Operating at a quiet 35dB and at a slightly lower price point, this smart litter box offers excellent value and convenience for demanding multi-cat or large-cat environments.
