`I've owned at least 3 other brands of automatic litter box but keep returning to this for the ease and simplicity. The size is just right and there are options to purchase a hood if desired. it's deep but not so deep as to become a mess. It is reliable and easy to clean. We are a multi-cat household and each prefers their own box...my only hope is that they eventually add a "health check" app to the litter box to notify owners if there is a health issue.....otherwise, good box!
