Every day, thousands of professors are burdened with the task of erasing white boards. Not only does this take a lot of time off lecture, but students are usually left dissatisfied with the chalk cloud left after the professor is done wiping, and the leftover lines are enough to trigger any person's OCD. This is why Smart Eraser is what everyone needs, an automatic chalk board eraser that can move up and down by itself leaving stunning results. The eraser is activated through a bluetooth sensor which tells it when to start erasing, and at the end of each iteration the eraser will always end up at it's highest point.
