Perfect? No. Better than vacuuming yourself? Definitely, Yes. After trying it out for myself, I'm sold. No longer do I have to spend the time, energy or backache getting the floors clean. Just set it and forget it. But don't forget to empty the tray every 3x or so, or you will be cleaning up after it. Does a surprisingly good job. Remove electrical wires and other obstacles or set virtual walls for boundries and you'll be amazed at the results. Does an average size room in around 60 minutes.
