I know a colleague who bought the Braava, the mopping robot made by also manufactured by iRobot (the Roomba's manufacturer) based on my guarded recommendation that it has limitations, but it is still pretty helpful. She came back and said that she was happy having a device that reduced the number of times she would have to do the mopping herself. I agree that the marketing behind these devices over promises their real-world capabilities, but if compare this marketing to that of other kinds of appliances and household products, then it is pretty much the same. Maybe totally honest accounts of product performance don't sell well because potential customers have been conditioned by marketing that promises the world?
