To make everyone do housework voluntarily.


To make children be willing to help their mothers doing housework,we invent this device called "Copier".It can project "monster" images to where the trash is in the house after scaning .Children could clean it just like playing a game, so they would never feel bored when doing housework, at the same time, it reduces mothers' burden. With Copier, keeping the house clean is easy and funny.
