Well, you'll find a Roomba spokesperson saying that, anyway.
I don't mean to imply that the spokesperson was lying and these were plain old roomba's instead of special R&D Roomba's.
I do mean to imply that I think a roomba spokesperson would describe "included in paragraph 12 of a 23 paragraph terms of service that they clicked through" as "specifically aware", but I would not consider that any kind of "proof" that the people actually were "specifically aware". At best it is an argument they ought to have been, which is a different thing (and it's an argument).
