Automatic wall-mounted foaming liquid soap dispenser for bathroom, hotel, restaurant, shopping center (white)

How to extend its lifespan? Why does it stop working after several weeks? 1. If you plan not to use it for an extended period (more than a week), please empty the internal liquid. 2. After each use, before refilling with hand soap, please run the internal automatic cleaning mode for approximately 2 minutes. Otherwise, the internal tube will become blocked and will not function properly. Ideal design: There are three levels to adjust the amount of foam, which can meet the different needs of adults and children: 0.6s, 1s, 1.5s. It can display the remaining power and internal temperature on a full screen. Extra-large soap dispenser: The 280ml capacity makes it ideal for touchless dispensing of liquids, hand soap, soap, and detergent. The soap dispenser is suitable for kitchen sinks and bathroom countertops. It is not recommended for use with granular or thick gel soap. High 2000mAh capacity: one charge provides up to 10,800 uses. The high-capacity 2000mAh lithium battery offers a long standby time of 3 to 6 months. Rechargeable and waterproof: Features smart charging and IPX5 waterproofing. Convenient and easy to use, no disassembly required, reducing the risk of damage to the dispenser's lifespan.
