iROBOT: Too Obvious A Macro-Trend

Obviously, you do not vacuum your own floors. You do not need to be elderly, you can be young and lazy. Roomba is fantastic !!
This product is the only thing that I would consider really revolutionary-- whether on the battlefield (mine detection) or in your living room. Everyone wants something to vacuum their floors without complaining.
Your charts and numbers mean nothing.
