Our touchless sensor pump Max is designed for commercial use but is also perfect for busy households. It allows everyone to wash their hands with soap or disinfectant without leaving germs for the next user, ensuring cleanliness and safety. It features clog-free pump technology that guarantees a precise and even flow, and the silicone valve prevents unsightly drips. To control the desired amount of soap, you can position your hand close to the sensor for a small amount and further away for more. The secure lid can only be opened with the included tool for refilling, while the large opening allows for quick and easy refills. It is powered by four D-cell batteries that can last up to a year. The sensor pump Max comes with a 32 fl. oz. unscented disinfectant refill pouch and an optional wall mount (screws included), allowing you to install it and keep it out of the way. Its sleek design enhances any environment. Use simplehuman soap or disinfectant for optimal pumping performance.
