We do around 2 loads a day and I have to tell you, this is the first washing machine I ever owned that I did not have to push back in place. All my other ones would shake its way out of my basement... I don't know how it works, but when I watch it, it looks like it goes through a balance test before each load. This thing is amazing... Just don't forget to let it run through start up mode when you first install it. (Read Booklet)... Oh, clothes come out clean too. [This review was collected as part of a promotion.]
