Not to be mean...
But if you really wanna see, how well, newer, front loads, and top loaders *Can* clean, try this experiment..
Fill your Kitchen Sink, with Warm or Hot Tap Water, and pour in a cap (Line 1 or 2 of Tide Liquid) and drop in a stained garment. (In my Case, it was a shirt stained with BBQ sauce) just with, well, a little agitation (with your hands) in the water, you can actually see the stain just lift and go away.
Being as though the Detergent Solution, isn't so diluted, and spending time, trying to soften all the water in a top loader, you achieve better stain removal performance, and results.
The Concept really in a Front Loader, is to tumble, and tumble your clothes over & over again (more gently, I may also add) in a detergent solution, sitting in the bottom of the tub. It's basically a clothes washer, that soaks your clothes, and agitates them slightly enough to take full advantage of the detergent being used.
The Concept of a Top Loader, is to roll the clothes, through the wash water, and pull them downward (through the detergent solution at the bottom of the wash basket, and back up, and over again) and while, I'm not going to say, this isn't a effective cleaning technique, I do believe the Front Loader, really can deliver a better cleaning result.
I'm sure a lot of you will disagree with me, and say, I'm wrong, but, I've been on both sides, and this is what my opinion is. I think clothes come out noticeably cleaner with a front loading washer (especially our socks) and when loaded properly, with the right detergent & water temperature, one can clean anything no matter how soiled.
The one thing that I really do like about Top Loaders is, however, how quickly one can load and unload one. Seriously, you can load in lightly soiled Clothes, and in half a hour, there done and ready to be dried. Try getting that from a Front Loader.. You'll be disappointed.
