Smart Display: By adding cleaning gel to water in a ratio of approximately 1:3, the soap dispenser automatically produces a dense, thick foam. With a button on top, you can choose between four different foam levels and easily adjust the amount of foam to individual needs. Electric Soap Dispenser: This automatic foam soap dispenser uses advanced intelligent infrared sensor technology, eliminating the need to touch the dispenser. It quickly dispenses soap foam in 0.25 seconds, making hand washing more convenient and hygienic. The touchless design prevents stains from remaining on the device and protects you from bacteria. Easy Installation: Two installation options are available: tabletop or wall-mounted. The foam soap dispenser can be wall-mounted without tools or drilling. Simply attach the clips to the wall after cleaning and hang the soap dispenser. You can also place it directly on your countertop. USB Rechargeable Soap Dispenser: This electric foam soap dispenser has a long-lasting, built-in 500 mAh battery, so you don't have to worry about replacing it too often. When fully charged, it can last for more than 3 months of continuous use. When the number of lights decreases, the battery is low and it will remind you to charge it.
