The backyard cookout is the hallmark of summer. Fresh air, hot eats, and good company—what's not to love? The only downside to a barbecue may be the baked-on grease it leaves behind on your grill grates. What if you could press a button and let the grill clean itself while you eat? That's where the Grillbot comes in. This rechargeable robot can clean even just-used grills, and because it's dishwasher-safe you'll never need to break your back to clean it. Available at Amazon; $79.
