After so many burgers, dogs, and racks of ribs, the grill is going to be filthy, and eventually someone will need to clean it—a job most people don’t enjoy. That’s the market niche for Grillbot, an automatic robot that cleans the grill while your clients are doing something else. Turn it on, close the lid, and walk away. The rechargeable bot has settings for 10-, 20-, and 30-minute scrubs, and has either brass or stainless steel brushes for cleaning different types of grates. The company says it can be used on any type of grill. Grillbots come in red or black and retail for $130. Grillbot, 800.854.1576,
