Put your feet up after working the grill and let the Grill Cleaning Robot handle the clean up. Like a Roomba for your grill, the robot has three electric motors and a built-in CPU that rotate three cylindrical brushes that remove burnt bits of food and grease from your barbecue grill grates. Its brushes' brass bristles will give your grill a thorough cleaning without scratching stainless steel or porcelain surfaces.
