Abstract
An improved laundry washing machine is provided with multiple fluid storage tanks for fluid detergent, bleach, and/or fabric softener. An air pump pressurizes the tanks when the door of the washing machine is opened. Each tank is in fluid communication with an associated fluid compartment. A user can push a control button to open a valve to selectively deposit a desired amount of fluid from a tank into the associated compartment for a wash cycle.
