Compared to most other cities, Montreal's metro stations are kept in very good order. Sure, there may be a pile of puke here and there on a Friday night, but in general, the city's metro stops are pretty pristine.
Yet, you never really see anyone cleaning the metro, save for that random guy with a broom who pops up now and then.
Who does all this cleaning? Metro fairies? STM-bots programmed to clean? No, its the hardworking sanitary maintenance department of the STM.
How do they do it? Find out in the video below.
