Great for high traffic restrooms and minimizing the spread of germs, the automatic soap dispenser provides a contactless way to dispense soap. The large top loading opening allows you to make quick and mess-free refills, while the clear windows let you easily monitor the amount of soap you housed inside. Simply place your hand underneath the sensor and within seconds, a fix amount of soap is dispensed. Please keep the surface of the soap dispenser clean and dry. Wipe with a damp cloth. Suitable for liquid hand soap. Refrain from using soaps with beads or exfoliants. Operates on 4 AAA batteries. Batteries not included. Insert fresh and new batteries to ensure the product runs smoothly.
