I thought that the broom was that necessary instrument to clean the floor of a house, but after living a few months in Great Britain, an English colleague that I worked with explained to me that it exists a substantial difference between a broom and a brush. A broom is more commonly used to sweep the external floors (such as streets, garages, sidewalks etc.), while a brush is more used on internal and closed spaces (such as the floor of a house, pub or shop). Is that true?
