My Samsung bespoke combo washer dryer has that feature. It uses less detergent than we are used to so my wife uses pods, but I think this is better un general since the clothes come out clean even if they don’t smell like detergent. So not only do I not need to load detergent, I don’t need to transfer to the dryer. Still have to load sanitizer in unfortunately.
In the few months I’ve had the Samsung All-in-One my experience has been at least a 50% increase in time spent drying compared to an LG stack I had previously. Also, when complete, if you do get to it within 5 to 10 minutes of finishing, it feels damp, but that clears on its own after 15 to 30 minutes or so if it sitting in the dryer with the door automatically opened.
Very pleased with the experience personally. I am very happy to trade not having to transfer the laundry in the middle with it simply being done when I get back to it a few hours later. YMMV.
Samsung has both heat pump (the one talked about above) and vented (similar to normal dryers) versions. LG doesn’t have a vented version yet. Condensers are slower than heat pumps, if you don’t have a vent and/or a 240V outlet, heat pump is the way to go. I personally chose a vented one because it was replacing existing machines. In NYC, heat pumps are more popular since a lot of apartments don’t come with vents or 240V (and definitely in the UK where they put the washer/dryer in the kitchen, you also see these all over Japan, all heat pump versions).
