SQ is kinda backwards
Usually - with Whirlpool and such - their commercial units are upgraded from their residential line.
Better bearings, dampers. Those "wear down" items often get an upgrade.
With Electrolux and Miele, their commercial units are mostly independent of the residential units.
Miele blurs the line with their little giants, but while they look similar, they are quite different underneath.
For SQ, their residential units are basically just their commercial units sold under compliance with residential standards.
Maybe they would change some minor components like the belt or so to adapt for the different market, and certain features are different like water level selection, but the machine is basically the same you would find in a laundromat.
Programming though is majorly different especially on the FL side.
TLs are somewhat different as well in that regard.
sQ has the closest in terms of programming from residential to commercial.
