I can see it now: the barbeque was set to begin in an hour and the urban grillmaster went out back to clean off the grill. On his way out, he had to step over the Roomba. And a light bulb appeared over his head.
So twenty minutes later the Roomba is melted and there are carpet fibers embedded in the grill skludge. Then came an afternoon of guests asking what was that odd seasoning in the burgers, and his wife's betrayal, and the threatened lawsuits. But out of this perfectly understandable, albeit regrettable, chain of events came an idea: the Grillbot.
All I can figure is that these guys have never seen my grill. Sure, the Grillbot might clean it but then what's going to clean the Grillbot? A Grillbot-bot? And what's going to clean that? See where I'm going with this? I just have too much "grill-patina" to ever get clean without military grade explosives being involved.
Don't get me wrong, I think this is a great idea. But look at that thing. It's much too pretty to be set loose on a crud covered grill. Better just put it in a display case in the living room. But keep the charger; I have a feeling they'll be racing these things in Texas before long.
