Things I learned from going viral off a robot vacuum: ~ Always include brands, cause omg. It's the Roborock QX Revo, from Costco. That's what we bought. 🤣 ~ So many people are concerned with whether it cleans stairs. It obviously does not--and neither do I. Your staircases must be sparkling. Don't come to my house, cause LOL. ~ I have a golden retriever and a shepherd, for fur context. We vacuumed 1x / week before this thing. ~ I ran it 2x more just because it's so cool. ~ Still love it.
