Is there an unmanned floor washer, or an unmanned floor washer?

That's right, Baidu's words "unmanned washing machine, unmanned washing machine, unmanned washing machine" came out. Although these words are different, they are actually the same kind of machinery, as shown in the figure.

These can be found on Baidu's search homepage. I hope it helps you. Thank you!
