Panasonic Air-conditioner print ad

An air-conditioner that cleans itself automatically. This is a very interesting and potentially appealing product proposition. I would like to find out more about this latest invention as well. In the ad (and in fact MTR posters as well), AC robot is taken as the analogy with the product function that cleans your air-conditioner automatically. This analogy is unquestionably a valid one. However when I read on and tried to find out more, details about this technology are missing. It's a disappointment for me as a reader indeed. It's learning again that key message (product functional claim in this case) needs to be substantiated with well-elaborated supports.
