This unit blew away my expectations.  I've had a ductless washer dryer combo before, and it washed just fine, but it would blow around wet air for over 4 hours and the clothes would still be moist. Plus I would have to tear it apart to clean out the Duct inside the dryer part once a year to clean out the wet lint trapped in there. But all that is over cleaning is simple, it gets the clothes dry, and in way less time. And it's supposed to be super energy efficient (I just don't pay that close attention).
