Siemens new washing machine technology

A new breakthrough has been introduced by Siemens, a new technology that is able to optimize the use of soap in washing machines, the technology called iDOS is claimed to be able to save water above 7000 liters per year, with a precision electric pump and sensitive sensors that will add or reduce the amount of soap used for the washing process, this is very beneficial because
can save liquid detergent about 30%.
The way iDOS works starts from a sensor that will read detergent levels in water, a mini computer will process data from the sensor, each data back up will be different, such as data for washing and flushing, washing data to adjust the detergent pump according to the amount laundry, the level of dirtiness of the laundry and the material of the laundry, while for the rinsing process is determined by the water content, if indicated the moisture content is still cloudy or dirty then the washing process will be extended until the laundry is completely clean.
