Build it yourself Brush Robot

Instead of just letting another weekend go by without doing something great with your time. Now you can pick up a kit to create your own bristle-covered companion. The Brush Robot may not be a big talker, but he’ll listen to you all day long. He has moving eyes and can sweep across the floor while you kick back and relax. He requires 2 AAA batteries to keep him up and running. You can purchase him for £15.00 or about $23 from the ScienceMuseum.
