The sustainable use of resources was the central design objective in the development of the Notty soap dispenser. The combination of infrared-sensor technology and a micro-foam pump on the inside allows precise dispensing of soap amounts based on need. Able to also detect the size difference between the hands of an adult and a child, the sensor automatically adjusts the dosage. The removable bottle of the soap dispenser can be used multiple times as it is easily refilled. When Notty has not been in operation for over 30 minutes, the device automatically switches itself off.
