The difference is that Roomba's are used by millions of people around the world whilst Boston Dynamics robots, whilst impressive, are currently used by... nobody? Anyway, it's an apples to oranges comparison. Boston Dynamics are building incredibly expensive and sophisticated AI systems that will be first of interest to the military, who have very deep pockets and can afford to spend millions if it is deemed a good use of the money. Roomba are building stuff that can be bought by the average person on the street.
