"In a perfect world I suppose HE regulations never would have come down pike and Maytag could have continued building top loaders of old."
Actually, Maytags older models before the second rinse option came into effect in the early 90's are actually more conserving of water than a modern Speed Queen. Their larger capacity models used 19 gallons of water, so with a deep rinse and 1 minute spray rinse put it around 42-ish gallons total use. A Speed Queen TC5003WN washer uses 24 gallons per deep fill. With a deep rinse, spray rinse, and 2nd deep rinse, the machine is at a whopping 73 gallons per cycle.
42 gallons vs 73 gallons and the Maytag spins at full speed with a solid one minute spray rinse which totally negates the need for a second deep rinse more than 95% of the time. I'd say the Maytag wins that round of efficiency standards. That's not factoring in a full control of the timer, water water levels, and no dumbed down water temps.
