I know it sounds funny, but I grew up in a house without a dishwasher. And I remember how thrilled my mother was when we got our first unit, which was one of those on-caster jobs that connected to the kitchen faucet and rolled away when it wasn't in use. For her, it was one of the single best home improvement investments she had made up until that time, because it saved her from countless combined hours of drudgery in front of the sink.
That's a bit how I felt watching ReadyBot do his thing. I hope they actually get this into production someday, because I am just tickled with the idea of having a kitchen robot slave to do all the cleaning.
