Hmm, a brand new version of the Roomba! They might have changed the IR protocol for it. (Actually, I'm not entirely sure that all models even support IR control -- the manual says "optional accessory for selected models" in the Remote Control chapter.) I'll take a look around if someone has posted an updated config file... Edit: The Roomba manual also states that the "Home Base" and "Virtual Walls" will interfere with an infrared remote control, as they are apparently using the same IR ports for communication. So, you can't use the remote when the robot is near those items...
Can you tell me how limited the distance is? (There shouldn't be a range problem with Samsungs; I've been doing a lot of my testing on a Samsung LCD, and getting respectable range.) Thanks!
