Oh lord this again.
New machines 'can' work perfectly fine.
Over the past 10years, I've had a Maytag front loader, and now an Electrolux front loader.
They both use very little water, although, will do a healthy final rinse with water up to the door glass.
I've washed sweaty gym clothes, dirty, smokey camping clothes, paintball clothes etc, all with great results with no stains leftover or any smells lingering.
My parents have a Maytag TL 765 washer that's 7yrs old. It washes all their clothes, and their grandaughter's stained clothes, towels. Even dirty house rags. Set up properly, my mom has never complained about anything coming out stinky or stained.
My brother has an old Samsung TL (I'm frankly surprised it's still alive, but it is!) and they wash their daughter's grungies in there. They wash pet beds, pet towels, camping ware, sleeping bags etc. Again, it all comes clean, when properly set up.
They even did "reusable diapers" for a hot minute but then stopped. You may find interesting, to no fault of the washer. They just ran out of time, and thought it was grosser than they were willing to put up with.
I don't know what's up with your warped view of things Jerome. Practically everyone I meet in life are not walking around with stained, stinky clothes. And by now in 2025, the vast majority of them have a laundry set from probably around 2010 or newer.
