Laun- / Washing machine

There are many situations when we have to sort the laundries first before we put them into washing machine. Every time it happens, you would have to wait until enough quantity of the specific kinds of the laundries to stack so there is no way to get them done quickly. If needed to wash the small amount of the specific type of the laundries, you have to use a lot of water while there are only a few things to wash. Therefore, I suggest a washing machine separated into 3 different divisions which can save both time and water.
