Jetsystem+
Jetsystem+ Has load detection and can substansially reduce the wash time. "Normal" Runs assuming a full load, no matter what the wash load. "ECO" Well.. less water lower temp... it's pretty useless tbh.
Synthetics Jetsystem+ is quite poor also. Synthetic Normal can have decent interm spins depending on parameters but Jetsystem+ does bursts with no drain and reuses that water for rinsing.
