If you grill food you know cleaning the grill can be a pain. And the regular bristle brushes they sell to scrape off the burnt food are okay, but never get your grill as clean as you would like. Grill Daddy sent me a unit for review. This is one item that went straight to my Father-In-Law as he is king of the grill. Well, July 4th arrived and he was gone all day so I took it from him and cleaned the grill for the first time with the gadget. There is no electronics you just fill it with water and turn the dial near the top and it will let water come out. On a hot grill this will produce steam and that steam will lift off the food with minimal effort!
My opinion on it: Is it a miracle that will make your grill look like the one above? No, but it will work better in my opinion than the regular wire brush cleaner. And I don’t have to worry about batteries or anything its just water. Its a neat gadget and I have tested quite a few as seen on tv products and this one is actually doing what it claims 
Buy It: You can get the Grill Daddy at the As Seen On TV site and it retails for $19.95

Disclosure: Though product was provided for this review, opinion remain my own.
I have a Grill Daddy and really like it. I agree with you, my grill doesnt look like the one in the photo (that actually looks like a brand new grill), but it is easier to clean the grill with the Grill Daddy than just using a wire brush.
It looks to me like a broiler pan more than grill, weird photo, an actual brand new grill would have been a better choice. But yes it cleans better than just a brush and water is cheaper than any other cleaner
