5 hard. I needed it only for dry cleaning, I did it wet once and still realized that washing with my hands is still better! And after washing the floors, you need to ventilate the water container, and it ventilates for a terribly long time . So it serves me for almost a month and only collects cat hair throughout the apartment (two cats) and sand from the street - super, I'm more how! Where is it better?)))) I recommend, and even for such a price - a gift. Everything is strict, angrily and without bells and whistles! I recommend
