Mine is very simple: A 4 inch diameter frying pan I got at the supermarket for $6. Makes a perfectly round over easy egg and a perfect fried egg for DIY egg mcmuffins. Use it a minimum of six times a week.
I'm going to say the Roomba 980. It picks up all the food we drop all over the place.
We have something similar. Downside is he's very good at turning the food into poop
