Ecovacs

It doesn't need food, doesn't go for walks, and doesn't leave hair on the sofa - but it does bark, wag its tail, react to petting, and even express emotions in its own way. For three weeks, I lived with LilMilo, the new robotic dog from Ecovacs, and discovered an impressive product that even the real dog in the office sniffed with curiosity. So where does it fall short?
