This robot with a mild-mannered personality program (but no sex or gender, being a robot and all) works as a janitor, but suspects it was made for another purpose. Who made it? Where did it come from?

I didn't draw it, but the back of the robot and its arms can detach as a floating flying saucer-shaped thing. Two, two robots in one, ah ah ah.

This robot will have a name eventually, I guess. Maybe in a few years. Decades. Anyway it's my original character blah blah blah
