Keeping the floor clean is something that most people work hard to do. There are lots of ways that floors can get dirty. The world is full of mess makers. Although sweeping and mopping are ways to clean floors, vacuum cleaners are much faster and more efficient. Many people have robotic vacuum cleaners so that the floor gets clean even when they are busy!

ASSIGNMENT:

Your job is to alter the demo project in the following ways:

• The eraser sprite will move automatically instead as a result of the user pressing the arrow keys.
• You will need to decide how to best control the movement of the eraser (or vacuum). You will create a continuous loop which guarantees that all parts of the screen area get cleaned within a reasonable amount of time.
• Create two more mess makers which are new colors not already used.
