So you give us a questionnaire, but it was missing an important qualifier - "Why?"
Why were we told we could turn off the robot. That would, of course influence our decision.
In the questionnaire, I answered "off" to all four, as I was simply asked "what would you do". I would turn it off to save the battery as, when the children come home, I am sure they will need it as fully charged as possible, freeing me up to do my own thing ... Yaay! Robo Nanny!
