Talking about Robotic Vacuum Cleaner, you might first thought of the famous iRobot Roomba. It is fantastic but it is quite pricy too. There are many other robotic vacuum cleaners available in the market now, but not so many can perform as good as the iRobot Roomba. I found Neato as the one which is much cheaper than iRobot and also many people commented that it performs even better than iRobot.
