Hello Marsh, diamond drum designed refers to the drum's surface that helps prevent fabrics from sticking out and consequently being damaged. Advantages of having a Diamond Drum in your washing machine are as follows:
● Embossed washboard surface reduces the textile area being exposed to harmful effects of washing by conventional washing machine drums by 35%.
● With the Diamond Drum, the water exit holes are both 25% smaller and located deep within each diamond-shaped depression to prevent fabrics from sticking out and consequently being damaged.
● Its surface creates an environment for the gentle washing of clothes.
