If flaw #2 is critical, there are animals at home, a lot of wires on the floor - it's better to look after it with a camera and AI. Otherwise great stuff Different pros: 1. Eliminates the “headache” with mopping 2. Handles animal hair/long hair well 3. Works with Alice Has cons: 1. Small dust collector 2. Only laser navigation - does not detect small obstacles like wires (wound a patch cord around a horizontal brush), scarves (sucked in). I'm afraid to imagine what will happen if the cat secretly burps somewhere 3. Minimum equipment 4. Long charging
