maybe they're just not meant for high use, like at an office with couple of hundred coffee drinkersWeird even the cheapest Delonghi I had automatically cleans itself before it turns off after use. The only real manual cleaning is cleaning the brew head every few months and descaling the machine when prompted (you'll have to do this with a Nespresso machine as well anyway).
the container where the used coffee grind get discarded fills up over time and needs to be emptied at least once a week
the "cleans itself" bit is great, but when you are waiting to make your cup that long delay is quite irritating
both of those likely much less of an issue with less frequent usage
