It appears that we’re safe (for now) from killer robots, so we might as well make them do some stuff for us. First on the priority list: cleaning that dang grill! Seriously, we’ve been known to go a whole summer without wiping it down, and trying to scrape fossilized fat off your grid in May is harder than finding something of value in Jerry Springer’s “Final Thought.” Inventor Ethan Woods has mercifully given us Grillbots ($69.95-$99.95), robots that will clean the funk and gunk from your grill without you having to move a muscle. Replaceable brushes take their time in removing the grime from both gas and charcoal varieties. Clearly this is a step up from R2-D2.
