Hong Kong is home to 7.4 million people where millions rely on public transit. So, when the COVID-19 outbreak hit, the government-owned Mass Transit Railway (MTR) shifted into high-gear to disinfect its subway cars and stations. It deployed a fleet of 20 disinfecting robots to do the job.
These powerful robots have been compared to a “mini-fridge on wheels,” but with a mighty germ-killing capacity. They assist staff by spraying a hydrogen peroxide solution onto surfaces and gaps that are in hard-to-reach places by hand. These impressive robots can be remotely controlled within 66 feet (20 meters) or can run autonomously by pre-setting the floor plan. One bot reportedly takes about four hours to clean an entire 8-car train.

In addition to subways, the disinfecting robots are sent to decontaminate areas with confirmed COVID-19 cases. These squeaky-clean bots come with a hefty price tag, however – $129,000 (HK $1 million) a piece for a fleet of 20.
Hong Kong has impressively contained the Coronavirus with a total of only 129 cases confirmed on March 11th – 39 of which reportedly came from outside its borders.
