A button on top allows you to choose between four different foam levels for a personalized experience. Electric soap dispenser: This automatic foam soap dispenser uses advanced smart infrared sensor technology, eliminating the need to touch it. It quickly dispenses soap foam in just 0.25 seconds, making handwashing more convenient and hygienic. The touchless dispenser prevents stains and protects you from bacteria. Easy installation: Two installation options are available: tabletop or wall-mounted. The foam soap dispenser attaches to the wall without tools or drilling. Simply attach the clips to the wall after cleaning and then hang the dispenser. You can also place it directly on your countertop. USB rechargeable soap dispenser: This electric foam soap dispenser has a built-in 500 mAh battery for long-lasting use. You don't need to replace it frequently when fully charged.
