Which feature is associated with Violet, the virus-killing robot?

Violet, the virus-killing robot, utilizes ultraviolet (UV) light to effectively sanitize environments. UV light is known for its germicidal properties, making it capable of deactivating viruses, bacteria, and other pathogens. The effectiveness of UVC light in sterilization has been widely recognized, especially in healthcare settings, to reduce the spread of infectious agents.

By using UV light, Violet can reach surfaces and areas that traditional cleaning methods may miss, ensuring a more thorough sanitization process. This is particularly important in spaces where cleanliness is critical, such as hospitals, schools, and public transportation. The technology employed by Violet reflects an advanced application of UV light sanitation, which enhances health and safety protocols, especially in the context of ongoing concerns related to infectious diseases.

The other features mentioned do not accurately describe Violet’s primary functionality, which centers around its use of ultraviolet light for disinfection.
