A new robot could help stop people from becoming ill by cleaning hospitals with light.
The robot, named Xenex, uses a UV light system to break through germs, WJLA reported.
It is thought that the cleaning process could not only protect against viruses, but also other illnesses which are more deadly.
The robot has even shown signs of reducing strains of anthrax and Ebola on surfaces.
Christ Hospital in Ohio had five of the robots delivered yesterday and chief operating officer Deborah Hayes believes it's one of the most powerful patient safety tools ever invented.
Each robot costs $100,000 (£81,000), but the company that makes the robot claims that if just five patients are protected from a major infection as a result of the robot, the hospital will have recorded most of the cost.
