It doesn’t matter if it’s called a BBQ, a grill or a Barbie; those char-grilled steaks leave a thick layer of grease and grime behind. And while cooking is fun, cleaning is not. What you need is a neat little R2D2 to scrub the filth away, leaving you to crack a beer and get ready to fire up the next BBQ. Enter the Grillbot, a cute, single button operated bot that perches on your grill and lives to clean. It works automatically on both gas and charcoal grills (hot or cold).
