Hi Joanne,
I'm not sure what you mean by "thumpers", but I can tell you that the WF42H5000AW is equipped with Samsung's Vibration Reduction Technology which helps to significantly reduce noise and vibration, even upstairs and at high spin speeds. It is important, however, that the Washer be installed and leveled properly on a sturdy, level surface.
Thanks for your interest!
Ms. Samsung
