you have to get past the mental thought of cleaning only happens during agitation....
if you really watched one of these machines in action......cleaning starts just after the start button is pushed.....
first is the Catalyst Pre-Treatment of a heavy dose of detergent lather.....like washing your hands, a good dose of soap, and a bit of water, lathered up real well, over and under, and completely through all parts, then rinsed clean under running water...
I can't say that its a perfect wash for a big puffy comforter, but for blankets and quilts, it does a decent job......
for most people, how dirty do your clothes actually get?.....unless your a mechanic or washing soiled cloth diapers, there may be a concern...but not really, I have access to both for test loads, it does a great job....
you have to load properly, set the controls for the correct cycle....and let it do it's thing.....
all I can really add, since I have both models, the direct drive functions better than the belt drive....I have an older model without the DeepWash feature, but on the DD I do have the waterfall, which is an added benefit....
newer machines are being built to correct errors from the past ones....probably best advice for any of them, steer clear of the 'normal' cycle for best results......
