a lot of people followed CR like it was the Bible...in their reports, and even today, they rate efficiency, not effectiveness of cleaning from machines...
people who owned SQ ST machines, for the most part wanted the same thing again, of course by this time Raytheon took over, and the consumer was sadly disappointed in what they got.....a reputation ruined too far until Alliance took over...
there wasn't much difference from a commercial machine versus a home machine....yeah, banging solenoids...the reversing motor only added a pause between wash and spin.....same fluid drive, transmission, pump, basically the same internals...energy savings came more from a motor that didn't run the entire time the machine was on...
I always say don't knock a machine until you actually use one, or work on one...there are pros and cons to everything....
best test always for a clutch/slip design is reach in and grab the agitator while its in motion....notice you can stop it...
your not going to stop machines like a 1-18, FilterFlo, Whirlpool/Kenmore, SQ ST...they will power through that load....
