They are sold in some countrys arround Europe.
The dryer does not recycle energy. It dumps it into the room. And the condensat tank is about 5l, so nearly 2 gallons. And you pretty much have to empty it every or every other load. And in fact, they do reverse!
The dryers, by the way, have brushless motors like many Euro dryers these days. When using the Wool cycle, the drum spins for the most part of the cycle, preventing woolen items from excessive tumbling. The blower has its own motor, of course. Not sure if that feature will be included in the US version, though.
These look to be the De-Luxe version of the AEG Protex range, the mid point of Electrolux Groups offerings.
Electrolux Laundry especially automatic washers and dryers have been around decades and are accredited both in Commercial and Domestic Home Laundry.
It does make me smile that all Europe and other continents have a "Standard" range of appliances yest in USA are marketed "Compact" is it not that the rest of the world is normal and yours are "LARGE"? dunno!!
E-lux's previous 'extra rinse' implementation worked like this:
The 'e-r' switch turned on the pump halfway through the 3rd rinse. Then the waterlevel switch turned on spin. When the timer turned both those off it went into refill for the second half of rinse 3. Rinse 4 was always active though the timer dial labelled it 'extra rinse'. It was also 'warm' if warm rinse was selected but only the final rinse was warm.
With the e-r switch off, rinse 3 simply tumbled twice as long, skipping pump/spin/refill. However, this applied to the clockwork timer. No idea how it's implemented in digital.
How many extra rinses can be added depends on the software. The manual for the Australian version of this machine speaks of "rinsing phases" that can be added. I looked at my AEG/Electrolux IFA videos on YouTube and saw that certain (higher end) AEG models allow up to five extra rinses.
I have the AEG clones of these e'lux machines and yes one can add up to 5 extra rinses - the standard rinses are 2/3/4 depending on cycle and amount loaded. Duvet (comforter) cycle and any cotton load in excess of 6kg receive 4 rinses automatically.
