A guerilla-style performance for autonomous cleaning robots. The robots are set down in a public location and as they clean they chat using text based on the plays of Bertolt Brecht, Jean Genet and Peter Weiss. They are aware of people passing, or stopping to watch and listen to them. They respond in a variety of ways depending on their mood. They may be jocular or irritated, but their remarks always point up the differences between workers and the rest.
