Siemens i-Dos is the first machine with integrated precision dosing system. Behind this innovative design is the idea to automatically dispense exact doses of detergent in order to save earth dwindling water resources, time and energy. The vast majority of consumers dispense much larger than necessary amounts of detergent, increasing foaming which in turn leads to additional wash cycles, causing washers to use exponentially larger amounts of water and cause environmental harm. The i-Dos automatically dispenses the exact amount of detergent needed for each wash. Siemens.
