As One Sees Things
Regarding top loading H-Axis washing machines, do not think they would sell very well in the United States, and one says this after using the things countless times in France.
Once you start to go above the "small" capacity of most European TL-H-Axis washers you start to bump up against stability and design problems. For all the size of the Staber washing machine, even Consumer Reports (yeas, I know), took points off because it was almost as big as a standard top loader, but lacked same capacity.
To begin to hold 121bs-18lbs of wash, one is going to have to move to perhaps the side opening "front loaders" that look like long troughs, think the F&P top loading dryer. However H-Axis washers of this variety do not have very high extraction levels, so the savings to come from less time in the dryer might not satisfy "Energy Star".
