The cleaners of the two sacred Masjids in Mecca and Medina play an important role in making sure that Masjids are kept clean. To achieve that, nearly 200 officials and seasonal employees, 2700 workers, 260 controllers and 100 supervisors are employed.
The following documentary details the work of The Department of Cleaning and Furnishing at the Grand Masjid in Mecca. While this documentary is far from perfect — it highlights the efforts of the Saudi government more than it talks about the people who actually do the cleaning, and the text to speech narration pronounces several Arabic words incorrectly — it still offers a rather touching overview of the entire process.
