1. A washing machine comprising:
- a cabinet;
a tub inside the cabinet for retaining wash water;
a drum inside the tub for holding and selectively moving laundry;
a friction member inside the drum for generating a water current in response to drum movement, and a friction enhancer coupled to the frictional member;
wherein the frictional member contacts laundry when the drum moves such that a friction force is established between the friction member and the laundry; and
wherein the friction enhancer increases the friction force between the friction member and the laundry.

Abstract
Washing machines having improved frictional forces with laundry. Those machines include a cabinet with a door, a tub inside for retaining wash water, and an internal vessel, inside the tub that is coupled with a motor that rotates the internal vessel. A friction member inside the internal vessel rubs against laundry. The frictional member includes a friction enhancer, such as a spherical structure or a freely rotating ball, that enhances laundry friction during washing and reduces adhesion of laundry after a dehydration cycle.
