First of all, you have to do two tasks, namely describing this device and showing how it works. But as you wrote, the first task seems to be missing. Describing here, as the way I thought, not to show how it looks but more relevantly describe what it is used for.
Secondly, doing the second tasks, I think you should explain clearly what it means by Automatic. Afterward, explain how to control/setup this device for some specific purposes, for instant, show how to make a pizza.
Nevertheless, I double that this device is so common that one can find it in any kitchen nowadays, particularly in Vietnam and/or other developing countries.
