With the COVID-19 pandemic, an autonomous disinfection mobile robot became a necessity. A disinfection solution should be designed to help facility managers control the spread of disease within their facility by autonomously patrolling and disinfecting indoor areas of the facility. Two disinfection modes are required for proper Covid-19 protection, namely: biocide spraying functionality which is useful for large area disinfection during periods when your facility is free of people and UV-C ultraviolet light disinfection, which is fast acting and enables a short disinfection cycle in between room uses and between meetings and once completed, the room can immediately be reused.
