The unmanned antivirus robot for COVID-19 use short-wave UVC ultraviolet rays for disinfection and sterilization. Within a few minutes, the DNA and RNA of the bacteria are destroyed to make them die, which can effectively achieve the killing effect. After testing, in the high-level disinfection mode, the spores and various multi-drug resistant bacteria on the surface of the environment (smooth surface, rough porous surface) can completely achieve the 99.9999% killing effect of high-level disinfection requirements.
