1. With high technology all components (sensor, circuit, pulse solenoid valve, thermostat and battery) are design in the faucet body. So, its installation is very simple, the same as common faucet. 2. water saving water flows out when your hands approach it and stop immediately once you draw them back, ,the water stopping time very short, saving water dramatically. 3. Hygienic the touchless faucet switches on and off automatically which is convenient hygienic and efficient to avoid bacteria mutual infections. 4. power saving for 6V lithium battery, it can be used for 5 years based on 300 cycles a day.(caution the batteries should be produced within half a year by qualified factories) 5. Convenient to maintain it is very convenient to remove sundries in water within its build-in strainer. The electrical sensor and circuit components can be all changed. 6. Elegant figure its linear design caters to the latest trend. 7. Detection distance adjustable itself it can self adjust its detection distance according to basin and use conditions. Self adjustment avoids adjusting the detection distance continually caused by the change of using conditions. 8. Convenient installation its sensor, solenoid valve are all in faucet body, making the installation easier and more convenient.
