Robotic mops and vacuums are getting smarter all the time. The LG CordZeroThinQ Robotic Mop is a new one that can keep your floor clean without you having to break a sweat. It has dual eye cameras to detect objects and people around it and avoid obstacles.
The LG CordZeroThinQ Robotic Mop can combine with the CordZeroThinQ R9 robot vacuum over WiFi. This enables it to start mopping after the cleaning process is done. You can catch these robots at CES2020.
