I have a pair of these machines and they really are outstandingly good.
They have swapped the doors around on the new range I think because it followed the logic that people move things left to right and start with the washer and move to the dryer.
I'm glad to see they've updated the Twin DOS button. I would assume that was because of feedback in Europe and I wouldn't be surprised if it changes here too. The original layout works but it's too easy to forget to put the system on. It has a single touch button that triggers a menu asking you about Whites/Coloured clothes and light (less detergent), normal or heavy (prewash-added) soil levels.
Being able to leave the automatic dosing on permanently would be very useful but for some reason the designers don't let you do that on the model I have anyway. You have to activate it each time. That works OK if you're careful but we've one member of the household who keeps accidentally running the machine without any detergent.
Other than that they're very very good machines from a technical point of view.
Also the dryer is just too notch. Yes it's not huge by US standards but it's a very practical system and it gets the job done very gently and with minimal energy. We run the dryer a lot and going from a vented Miele to that T1 machine has cut the power consumption by a huge amount and I would much rather not add unnecessary emissions to the environment by using a dryer that's basically heating the back yard.
The washer is extremely quiet and the dryer is about as quiet as a dryer can be without putting it into a sound proof box.
Also the amount of heat they throw out to the room is minimal. They're nothing like a traditional condenser. They do release a little bit of heat but it's probably less than you'd feel from an externally connected vented dryer.
Also the Miele system for keeping the condenser clean is simple - a very very good filter in the plinth and two stage filtration in the door. Bosch messes around a lot with self cleaning condensers they rely on flushing the condensate through the condenser. Miele is far more simple and practical.
Word of warning:
Never, ever, EVER EVER even think about using dryer sheets in a heat pump dryer! You will cost the condenser and reduce the life of the machine. Also they just don't work as you won't get the same temperature profile as a traditional dryer. If you want fragrance - add it as detergent or conditioner to wash or use the Miele fragrance flacons.
Also the Miele detergent system is good, if pricy. The main thing to remember is it doses very precisely and quite sparingly compared to what you might do yourself and as a result you'll get a lot of washes out of one of the packs. Even so, it's still a bit eye watering pricy.
It basically consists of a custom manufactured high end colour detergent in the blue pack and a peroxide bleach (with optical brighteners too) in the clear pack. The machine doses the enzyme rich colour detergent first, does the breaking down of gunk phase then a shot of bleach goes in later, giving you a bit of oxidation and brightening.
If you select colours, as far as I'm aware of doesn't dose anything from the bleach cartridge.
So basically you're getting something closer to a commercial machine using component detergents.
The machines don't dispense fabric softener automatically, unless you opt to use the refillable tanks and just use a normal liquid detergent in tank 1 and fabric softener in tank 2.
Also I think the pod dosing is a complete gimmick! It's also an incredible waste of plastic and I'm really a bit surprised Miele even launched such a thing!
Their wool / silks detergent is excellent but just get the big container full of it. There's absolutely no advantage whatsoever to the pods. It's like Nespresso for washing machines! Only less useful.
