Use touchless technology to keep your hands clean with Umbra's Otto Sensor Soap Dispenser. Designed by Dennis Cheng, its sleek profile looks great in any kitchen or bathroom. The innovative sensor pump technology automatically dispenses a fixed amount of liquid soap. Otto can be filled with dish soap, liquid hand soap, or hand sanitizer. The fluid level indicator window lets you see when it’s time to refill and the large, top-load refill opening makes topping it up quick and easy.
