Refers to the last member or the tail of a climbing group. The sweeper's task is to spot and retrieve things that may have accidentally fallen from the preceding climbers; to make sure that no mess or gear is left behind; and to make sure that the rear is keeping up with the whole team. The term "sweeper", a Filipino contribution to mountaineering vocabulary was introduced in 1998 and was inspired by The Cleaner character in the 1990 film Nikita, also known as La Femme Nikita by Luc Besson.
