Automatic soap dispensers are devices that dispense liquid soap without the need for physical contact. They use sensors to detect when a hand is placed underneath the nozzle, releasing a pre-measured amount of soap. This feature helps reduce the spread of germs and promotes better hygiene, especially in public restrooms and kitchens. These dispensers can be found in various styles and sizes, often powered by batteries or electricity. Many models are designed to hold different types of soap, including liquid soap, foam soap, and sanitizer. Their convenience and efficiency make them popular in both commercial and residential settings.
