One of many ways true industrial washer/extractor differ from domestic machines is their ability to perform "sluice" cycles. That is remove bulk soils and foul matter from laundry.
Industrial or commercial diaper services either for infants and or increasingly being offered for adults do not "flush" or rinse soiled linen. Everything is bunged into washer where one or more flush cycles will send solid matter down drains.
Such washer/extractor have larger diameter holes in tub (better to allow foul matter to exit) and of course have dump valves, not pumps. This reduces chances of foul matter being carried over to subsequent loads.
Domestic washing machines cannot handle sort this sort of laundry, at least not returning consistent hygienic results.
Old school wash cycle for diapers at commercial laundry:
(1) Five-minute cold rinse;
(2) 10-minute soak in hot suds;
(3) 10-minute soak in hot suds;
(4) 10-minute soak in hot suds, with bleach;
(5) five hot rinses with live steam;
(6) six cold rinses, and a germicide solution is used in the third cold rinse;
(7) water is extracted; (8) dried in tumblers under 125 pounds of live steam;
(9) ready for folding and packing.
After all that all fecal matter is *gone*.
OTOH it explains why cloth diapers have (or had) such short useable lifespans.
