Programmable Lego Vacuum Cleaner/Mop

It is a robotic vacuum cleaner that is made from LEGOS. It is programmable and it has sensors so it goes around the house and cleans up the ground. I built it because I thought that people would be able to learn programming and at the same time create something that can clean their house. This would make a great LEGO set because not only does it just let you have fun and creative, but it also allows you to create something practical where you can use it in a real life scenario. The image below is not the real thing, just a sort of prototype on a much smaller scale
