If your answer is it’s an intelligent machine. Then the products at iRobot should interest you. The product has intelligence built in, it won’t eat your cat. It does what you want , which is clean your floor. The drawback is, who empty’s the device? You do.
So while we have been living with robots for a while, they always leave something wanting. We have become slaves to the devices, we need to maintain them. Maintaining them takes our time. This violates "Bill’s law of computing", “I don’t work for the machine, the machine works for me”. Then we know that iRobot has a ways to go, in order to satisfy that demand. The Karcher seems to meet that demand, yet the current leader has not taken up that challenge. So the new question is, is a robot a toy or a useful machine. If you answer both, you will have more fun!
