Title: Not worth the money.
Review: The device is very well designed and easy to use. That said, be aware that the batteries die after just a few uses and at $60 each to replace can be very expensive. Irobot's customer service is a joke, so buyer beware - you are on your own when it comes to troubleshooting a problem.The machine gets stuck easily and will go right through the virtual wall on occasion. It is not worth $300. You can get an upright floor cleaner that will do a faster, better job for the same money.
