The Cleaners are an elite group of human mercenaries controlled by Alexander Corvinus in Underworld: Evolution. They use the latest technologies and are seen dressed entirely in black at all times. No badges or other insignia betray their identity. Their leader is a man named Samuel.
The Cleaners are recruited from most of the world's major intelligence services, including the CIA, MI6, and Mossad. Some hail from the worlds of organized crime and the international computer-hacker community for the best talent available. This usually involves faking the deaths of new recruits, so that they become anonymous and untraceable.
The Cleaners were founded by Alexander to hide the war between the Vampires and Lycans from all mortal eyes. The Cleaners are used to "clean up the mess" left behind by the two warring species. How long the Cleaners have been working for Alexander is unknown, though it can be presumed that it must have been several years by now, as the Lycan/ Vampire war has been raging for over six hundred years by the time of the events of Underworld and Underworld: Evolution. It is possible that Alexander's original army may have later become the forerunners of what would become the Cleaners.
Though the Cleaners are not mentioned in the first movie, it is implied that they cleaned up the aftereffects of each battle between the Lycans and Vampires.
The Cleaners, led by a man named Samuel, go to the Lycan Den under Alexander Corvinus's orders and bag the bodies of the dead Vampires and Lycans, in particular the body of Viktor, a powerful Vampire Elder brought down by Selene. They return to Alexander's ship with the bodies of two of the Vampire Elders (Viktor and Amelia) and that of a powerful Lycan named Lucian. After a group of Hungarian police officers find one of the Vampire safe houses, the Cleaners knock the men out and blow up the safe house, insuring no one can corroborate the mens' stories.
Later, the Cleaners return to the ship to find Alexander has been badly injured by his son, Marcus. They retrieve Selene and then leave with her, in an attempt to stop Marcus from releasing his twin brother William, a destructive Werewolf who turns everyone he kills. Once in the dungeon where William is housed, they discover Marcus has already released him and the men begin to fall to William one by one.
After a short spate of fighting, only two Cleaners are left, one of them being Samuel. They regroup with Selene, but William attacks and kills both remaining Cleaners. The Cleaners then rearise as Werewolves, infected by William's bite. They attack Selene, initially overtaking her, but are slaughtered when the Lycan/Vampire Hybrid Michael Corvin comes to her aid.
