Model manufactured in 2015. Retail price: 89,880 yen. Operation confirmed. The main unit and dust box have been wiped down with disinfectant wipes. It connects to the app, but I haven't been able to start it via Alexa since this year, so I've been starting it manually. Please refrain from purchasing if you want to control it via communication. If you mainly use it manually, I think it's still usable. Also, of the two wall units, one powers on, but it doesn't function, possibly because it's not emitting a signal. Please purchase only if you understand this.
