Robot polisher for a cafe\restaurant. Whether there is a?

Question

Iron

Good afternoon!
There is a cafe, area 140 sq.m. Floor - tiles. It works from 10:00 to 22:00 (in fact 23:00). And there is a desire to automate its cleaning. Interested in washing floors, tk. just vacuuming will not be enough. During the day, the floor gets dirty very significantly. Food falls, ice cream falls, drinks spill. Children are running all over it. In general, as it should be :)
Now the premises are cleaned after the shift, manually, by the workers. Cleaning up in the morning is a bad idea, because the floor is not dry.
I studied the market of various cleaning robots, but it seemed to me that they were all designed for home use. Maybe someone knows or had experience in robotic industrial cleaning.
I would be very grateful for any information.
