IRobot has no idea what Customer Service is & they don't care!
The machine is great, but if you need help - you better call a friend! The manuals are written for people who already know how to use this machine and service. The machine isn't so hard after you figure out the terminology iRobot uses. IRobot is very skilled at avoiding it's customer's questions. Use a different company and/or service - iRobot will take your money, but they do not care if you are able to use the machine or service options. Their software is some of the most UN-User Friendly I have ever encountered.
