I really am amazed that this washer dryer combo can sense and detect the soil level. My laundry is usually done in 2 hours and twenty minutes. I prefer to use the AI selction. My gentle clothes I really like the permanent press cycle. I have used the towels selection and then dry they come out so soft and fluffy. The automatic soap and fabric softener works really well. . I am impressed with the ventless system. I do find lint in the rubber of the door that needs to be cleaned of lint. I just bought the unit and learning about the different sections of wash and dry .
