iRobot Roomba Virtual Wall 2003 Robotic Cleaner

I bought the Roomba Elite Pro which includes 2 virtual wall units. They work exactly as advertised. Roomba doesn't go across the wall. I can push my mess to one side of the room, set up this virtual wall, and let Roomba run. When it's done, I push the mess to the other side of the room (which is now clean) and let Roomba clean the other half of the room. I can clean the apartment without having to clean-up first. Now, only if iRobot can come up with something that put stuffs back on the shelves....

One annoying thing is, it doesn't come with the 2 DD batteries required. It's not that expensive to include two cheapo non-alkaline batteries with the unit, consider how expensive they sell this thing for. People don't generally stock DD batteries. When we unpack it, we want to be able to test it out "right away".
