Here is another robot that can disinfect hospital rooms efficiently. LightStrike is a robot germ zapper from Xenex designed for ICUs, operating rooms, and medical surgery units. It uses UV light to kill most germs by bouncing it against the walls, floors, ceilings, and other hard-to-clean areas.
These robots can disinfect a patient room in 15 minutes. They have triple sensor motion detection and cloud-based reporting.
