One has to remember priorities there though.
These machines won't run 24/7, probably more like a few cycles a day max.
Then these need to be efficient - as long as they work, you can say you have OPL possibilities, and you want that as cheaply as possible.
And then it's the up front investment. If you have to buy 8+ machines at once, doubling the price is a HUGE difference. So on a pure ROI basis, buying cheap but more often can make sense.
So these machines offer cheap means to offer OPL with warrantys for such applications - NOBODY in an OPL setting would do repairs themselves, so having just parts warrantys still cover much of the issue for that setting.
There are a bunch of similar offerings by ELux and Whirlpool over here. They are usually aimed at things like hair salons, small eating establishments or multi occupant dwellings like assisted living facilities.
Once you go actually pro, there isn't much of a price difference between all the brands (Alliance Laundry, Miele and ELux). So it's usually down to who can fit your needs better, which has better support options in your location and often who you are used to.
