I never saw one remove any water. They take their tool and lay down whatever. Was told the dirt would come up when we vacuumed. My Hoover and Cross Wave deposit and pick up the dirt. Also less $. Though i do not know the charge today, back when, it was like $39 per room. I now only have to purchase the liquid for carpet, tile or wood. But then also have to provide the labor. I work inexpensively.
