@tess Reminds me of the old joke, Yeah we lose money on every sale, but we make it up on volume!
Really, there's a bright lining to this: I look at my Roomba that's been churning away for, what, fifteen years now? With only a few trivial repairs, and that's impressive to me.
So I end up laughing that the quote should be, "We SOLD vacuums to half the population," and for better or worse the robots may not be in need of replacement.
I'm a huge fan of #iRobot but at some point mature means solved, and there's little point allocating more resources to a project that's done.
Those resources are needed to work on the next problem, and it doesn't seem like iRobot has much to contribute there.
