Yeah I got one several months ago and can’t live without it now. Not sure about any other brands, but the roborock maps your house and let’s you set up schedules so it can do things like cleaning up around the litter box once an hour. It cleans the whole house before I wake up and stepping out onto freshly swept carpet every morning is amazing. Have a routine for after meals where it cleans the kitchen and around the dining table. But mostly yeah never stepping on litter again is amazing if you have a cat.
