Automatic foaming soap dispensers work by using an infrared sensor to detect hand movement. When your hand is placed under the sensor, it triggers a small motor to pump a pre-determined mixture of soap and air through a mesh screen. This process creates foam, which is then dispensed into your hand. The combination of soap, air, and water produces an efficient lather, helping you use less soap while ensuring effective cleaning.
