iRobot Roomba Model 4220 Vacuum Cleaning Robot effectively cleans both carpets and hard floors. Roomba cleans hard to reach areas like wall-edges and beneath furniture. It automatically avoids stairs and other drop-offs and Roomba even senses dirtier areas and cleans more thoroughly in those spots. At the end of a cleaning cycle or when its battery is running low, Roomba returns to its Home Base to recharge. Roomba comes with 2 virtual walls that keep Roomba cleaning where you want it and out of off-limit areas.

Oh, if you have only wood floors it will probably work flawlessly. We are 60% carpeted so it constantly will back away from going up on the carpets or runners, sometimes spin around and then walk up onto the carpets. And, watch out for the shagged ends on some rugs. What we do is just lift all the runners and get them off the floor. The tasseled ends would get caught but the Roomba would twist around to dislodge and keep on going.
Clean up is easy, if you don't mind dust, dirt and all else it catches in the tray. Just dump it in the garbage sack. Use gloves, if you are sensitive to all that stuff. The filter gets clogged every time we run it. So, recommend cleaning both tray & filter each time. It is not hard to do, in fact, very simple -- only two steps.
One last thing, it will hang up under low couches and chairs, gets caught -- then you have to go find it and redock to charge up the batteries.
By the way, the cats follow it around while it is working. Curious you know!
Overall, we are amazed at how well it cleans. The few problems, we can work around. I guess we'll keep it
