Traditional washing machines use approximately 35 litres of water per kilogram of textiles to be washed. A typical household uses up to 21 litres of water every day, just to wash their clothes. According to calculations, this consumption alone accounts for 13% of total consumption and equates to 455 million litres per day for a country such as England.
The Xeros washing machine was designed to help save billions of litres of water per year. And since it only uses up the equivalent of a single cup of water, the washing comes out almost dry, meaning that the dryer doesn't need to be used …
This is how it works: once the clothes have been put into the washing machine, all that needs to be done is to add a cup of water and small nylon beads which will scrub the clothes and absorb any dirt. At the end of the washing cycle, the beads fall into a tray underneath the washing compartment and can be reused one hundred times, which is the equivalent of six months of normal usage.
The plastic beads reduce water and energy consumption to 2% of that required by a conventional washing machine. Tests show that this new laundry system is just as effective, on all types of stains, as the conventional methods that use larger quantities of water.
