First time I've run it in the lab in ages and all the little metal bits I cut out of aRDui5X's shiny metal ass are still embedded in the carpet. Also it's ignoring the virtual walls. I know I'm mixing memes here but I had to vent.
You need a powerful vacuum to get those tiny metal bits out of the carpet. Roomba works, but it's not perfect. However, it make a good base for a butler robot... with the added bonus that it can also vacuum the rooms if needed.
