Thanks for the question, M&M. This and other Samsung Washers are designed to clean both effectively and efficiently. The WA48H7400AW uses the pulsator and drum action to move the clothes during the wash cycle, so there's actually more motion occurring under the surface than you're able to detect while watching it in action. Of the four components of effective washing (time, temperature, mechanical action and detergent), the speed at which the items move is not a key factor.
Thanks for choosing Samsung!
