Have never used an large Miele, but do like my Pfaff ironer. In fact considering recent prices for Thor GladIrons on fleaBay, may consider selling mine to make room in the laundry. Am only looking into this, as can do lots of small flatwork really fast on the Thor, and it gets VERY hot. The last bit is really needed for doing heavy vintage linen.
Picked up one of those Corby trouser press things for a few bucks at Goodwill. It was MIB and think we've used it only three times in 8 years. It may be going on the auction block as well.
One thing to remember about using ironers; ironed in creases are difficult to remove without re-rinsing the entire item. So if one makes mistakes feeding large items onto the roller, it can result in sheets with heaps of unsightly creases/lines that are ironed in. This is why I do large items on the Pfaff or on my ironing table/Proctor iroing board. It simply takes too much time to arrange/rearrange, turn over, feed, refeed, large items on small ironers.
Several things make me think Ironrites/Maytag/Simplex/Thor/Speed Queen and the host of other ironers may not have been used widely. One was the ease of laundry services, which were plentiful in large cities and even small towns. Two, there was until recently a plentiful supply of cheap help to either take in washing/ironing or do it as part of being domestic.
Finally keep coming back to the point that many women who knew how to iron, must have quickly felt as I did. Sod all this "Automagic" stuff, I can do it faster by hand. Thus the mangle became a large, heavy and rather obtrusive conversation item in a corner of the kitchen.
Mind you, some women became really good it mangle ironing. Many have told me fond memories of watching their mother or grandmother using a Ironrite/mangle.
There is much we can go into about ironers and other appliances introduced post WWII, supposedly to save "Her Indoors" time,and preserve her looks. Much of this had to do with post war production capacity shifting from military goods to appliances. All those factories from GM on down,needed to make something. Everyone and their mother was also trying to get newly returned GI's to part with some of the cash Uncle Sam was giving them. Easy payment plans appealed to a new young family. Marketing was aimed at men to make presents of these appliances to make wifey happy and preserve her looks. Hence the plethora of mixers, blenders, toasters, coffeemakers, and god knows what else that pops up at estate sales, much if it MIB. It wouldn't be until Betty Freudian wrote her book and opened many people's eyes that men understood a woman was not made happy just by having a whiter than white wash, or new washing machine.
