> They're called Roombas, and they're the highest selling vacuum cleaner on the market right now

A correction: they're the top-selling robotic vacuum cleaners. Traditional 'dumb' cleaners still outsell them by magnitudes.

Hmm, I can't seem to find my source to back that up so I'll have to concede that point. I remember reading something on HN a few months ago that the Roomba was the single best-selling vacuum cleaner of 2016, in the same vein that the MacBook is the best selling laptop even though all PC makers combined out-sell MacBooks.

But since I can't back up that claim, I'll give it to you.
