Love my toplader AEG for many of reasons noted in that YT vid. You can see why French homes, in particular flats, like these sort of washing machines. Never understood why top loading H-axis washers never really took off outside of France and few other European countries. Of course in North America there have been top/side loading "pony" commercial washing machines for ages.
One thing YT reviewer didn't mention, and perhaps it doesn't apply to his washer, is that by filling with warm or even hot water throws off washer's programming. Thus the confused appliance will shorten wash cycle (basically substracting portion of cycle allotted for heating water), and get rid of certain other bits as well.
Both my AEG washers will do this and it's sort of a pain in summer when tap cold water is quite warm. Not only will washers abort heating portion of cycle, but usually last ten or so minutes of recirculation spraying is gone as well.
As for balance of YT reviewer's comments, they were spot on regarding energy use.
Plenty of boat owners of all sorts face issues regarding running modern washing machines on "ship" power. This was less of an issue with older washers with electro-mechanical controls where temps could be set independent of cycle, and or were dual hot/cold fill.
