Robots are going to do many things for us in the future. There are already plenty of neat robots that can keep your home clean. The Neato Botvac D80 happens to be a robot that uses a smart mapping and navigation system to scan and map your room. It cleans your place room by room and goes back to the charging station when it needs more juice.
The Neato Botvac robot picks up dirt, crumbs, dust bunnies, and pet hair. It comes with a spiral blade and combo brush to handle all types of floors. Sets you back under $500 at this time.
