【Contactless Operation】Advanced infrared sensing technology enables precise contactless operation – simply place your hand within 0-2.36 inches (approximately 2.5-6 cm) of the soap dispenser to activate dispensing. The contactless design is more hygienic and convenient. The foam soap dispenser features a drip-proof spout, minimizing drips and residue and keeping your sink clean. 【500 ml Large Capacity Refillable Tank】This automatic foam soap dispenser has a wide opening and a large capacity tank, reducing the frequency of refills. A transparent window makes it easy to see the remaining soap level. It is suitable for various foam soaps, gels, and even diluted shampoo (regular liquid hand soap must be diluted 3-5 times with water), making it versatile. 【Four Adjustable Dispensing Levels】Simply press the power button to customize the desired amount of soap dispensed. Four adjustable dispensing levels prevent waste or insufficient dispensing. This automatic foam soap dispenser is ideal for homes and high-traffic areas where precise dispensing is crucial. 【IPX5 Waterproof Rating and Stylish Design】This contactless hand sanitizer dispenser has an IPX5 waterproof rating, making it suitable for use near sinks and in humid environments. Its modern, minimalist design seamlessly blends into any kitchen, bathroom, or office.
