The Roomba s9 is the grand daddy of robot vacuums with 40x times the suction of the 600 series vacuums and base station that will empty the vacuum for you after each use. This vacuum uses vSlam navigation technology. Not only does this sound cool, but this thing will collect data and scan ahead for obstacles. As it collect data, it will map your house and allow you to label the different rooms, so you can send it to specific rooms when needed.
As if that wasn't enough... It also empties itself after each use into the clean base which also charges the unit. The base station will hold up to 30 full bins of dirt, so you don't have to empty the base very often.
Here is a video by iRobot if you would like more details.
