SprayBot is a disinfection robot that sprays a vaporized disinfectant on a designated location. The process does not require human intervention, reducing unnecessary direct contact between people and ensuring the safety of staff. SprayBot can recognize passengers and stop spraying if it senses someone standing in its way, then start again once the area is clear. The robot has up to 6 hours of continuous working life, and will automatically return to charge when the battery is low. It supports fast charging, fully charged in 3 hours; its short charging time maximizes efficiency to meet demand. The device passed certifications like CE, FCC and ROHS to ensure quality and safety for all users.
