- 2021 latest automatic soap dispenser with a high-precision infrared sensor. It responds in about 0.25 seconds and senses at a distance of 3–5 cm. The filter and curved nozzle design guide the foam smoothly under your hand, making it easier for children to use and more hygienic than traditional dispensers. - Large capacity and adjustable foam volume. 300 ml visible liquid reservoir lets you easily check when to refill. Uses less soap than a manual push dispenser. Two foam quantities: small foam about 0.6 g (suitable for children) and large foam about 1.1 g (for the whole family). - Low noise, energy saving, and environmental protection. The small high-performance motor delivers quiet operation with low power consumption. After startup, the switch light and the foam volume selection light stay on for about 10 seconds, then enter standby. A green LED indicates charging and remains on when charging or full. - Wide uses and compatibility. Compact and convenient for private and public spaces such as kitchens, sinks, bathrooms, offices, hotels, hospitals, schools, and laundry rooms. Foam hand sanitizer can be loaded directly into the automatic dispenser.
