I let my current cleaner be around my kids.

Now the question is is it riskier to have basically a stranger with strong arms in my house near my kids, or a robot with strong arms in my house near my kids?

I feel like a robot has the technical capacity to see behind it and stop (I have many times for example been using the vacuum and moving my arm forwards and backwards and whacked a kid in the face with my elbow on the backswing because they've walked up behind me and I've not known, but a robot with literal eyes and radar in the back of its head would spot that situation and freeze). Similar to self-driving cars: they have lots more eyes than a human has, and can be looking everywhere at once etc.

But do we trust the programming? Do we trust the human cleaning my toilet's "programming" (thoughts, emotions, motives etc)?
