Do they still call it Jīqì"rén" if it's not human-like? Like a vacuuming robot or a robotic arm at an assembly line?

Yes, a vacuuming robot is saodi jiqiren (literally sweeping robot). Industrial robotics are gongye jiqiren in general, although a robotic arm is more precisely a jixiebi (literally robotic arm).

English also has "Android"
