Why are they cylindrical shape and not ball shape. Would that not be better for more random movement of the items inside and therefore be better for washing them?

Washing machines are not spherical because they need to have a cylindrical shape to spin the clothes around and clean them effectively. A spherical shape would not be able to rotate as fast or as smoothly as a cylinder, and it would also take up more space and use more water. A cylinder can also fit more clothes inside than a sphere with the same diameter.
A random movement of the clothes is not necessary for washing them well. What matters more is that the clothes get enough contact with water and detergent, and that they are rinsed properly afterwards. A cylinder can do that better than a sphere because it has more surface area for the water and detergent to reach all parts of the clothes.
