We call things AI until they start working. See also: robots (your washing machine is a robot, but it works so you don’t think of it that way).
I think of robots as general purpose, machines are specific purpose. When it works, we make it single purpose because that’s far far cheaper than general purpose.
Calling things "robots" is more about the amount of movement. Spinning in place like a washing machine sprayer isn't enough to qualify.
A paint conveyer belt is not a robot. A sprinkler system is not a robot. A CnC machine might be a robot. A conveyer belt that sorts items might be a robot. A roomba is a robot. And all of these function just fine.
