I got this used today and so far can't seem to determine if it is an iRobot 7 or not. Sorry if this is in the wrong forum. Obviously once it is identified, I will know where to look for proper support. The About Screen: The Plugin Profile: The back which is curiously blank: And last but not least the power switch side: (The top has basic menu button and volume rockers with mic on far right) Anything else that would be on the top of the unit is just single Circle with Square inside of it which acts as "back" button of sorts. The seller gave me a dongle which plugs into the unit which allows for 2 usb ports and 1 Ethernet port to be added to the system. Any help is much appreciated.
