Not sure how the machine can dose for the soil level of the clothes tbh, I suppose one advantage is it stops overdosing which many do in the mistaken belief it’ll clean better. I like LG machines as they filter the powder before it enters the drum, so its fully dissolved. and the way they rinse gets much more of the detergent out of the clothing. Which is my one of my requirements in any machine. Oh, the other thing is LG uses the inverter motor to directly drive the drum unlike the majority of other brands with still use a belt between the two. More reliable if no belt to snap, slip, stretch.
