Short cycles
Commercial/industrial h-axis washers of all sorts including OPL and laundromat are designed to have rather aggressive wash action. This usually means substantial lifter bars/beaters that lift and drop (ok slap) laundry against itself and wash tub.
Such washers can do in a wash cycle of 8-12 minutes what takes domestic machines thirty, forty or more minutes. For badly soiled wash there maybe two or more wash cycles, but none are longer than say 12 minutes. This explains why commercial washers of all types including laundromat machines have are done and dusted with total cycle times of usually between 20 and nearly 40 minutes. My AEG washers allot nearly an hour just for rinse and spin cycles. *LOL*
Regarding rubber door boot around tub, industrial/commercial washers never had them for h-axis washers for most part. There is a gasket around porthole which allows the door to be sealed directly onto the drum assembly without protruding into the washing space.
On most if not all domestic front loaders glass porthole protrudes into tub and are even designed to become part of wash action via sloped design that keeps wash away from boot.
Asko is one of if not only domestic front loader that comes to mind who don't use gasket around tub, but rather gasket/seal around door porthole.

There are pros and cons to each. Some consider boots unhygienic and just something that sooner or later will need to be replaced.
OTOH not having boot and just seal around door can lead to a few issues.
One is smaller items such as infant clothing (socks) can slip between tubs. It is suggested such items be placed in mesh bag for laundering.
Other issue is full door gasket around tub seems to be slightly better at preventing leaks. If you go to any laundromat and look at front of machines often you'll see tell tale signs water has leaked from door down front.
Usually this is caused by operator error; customer or laundromat attendant using too much detergent causing huge issue with excess froth.
Was at local laundromat week or so ago and Asian attendants are famous for not measuring but pouring liquid Tide into dispenser in heaps. This time the large >50lb washer had so much excess froth it not only was overflowing from door but backing up into next three washers in that row of machines.
