Samsung has effectively developed a robot vacuum cleaner that will be a opponent to the iRobot 560 Roomba. Identified as the Samsung Furot II, the robot has a fixed camera to help avoid any obstacles on its path. It even has a memory that works when the Furot II is off. So if you have surpassed its 90 minutes worth of attack time on its battery, you can recharge it and the Furot will lift up where it left off.
