What is Cleaner?
1.
A specialized person who removes incriminating evidence from a crimescene (usually one involving murder) in order to make the legal consequences of the crime go away.
Cleaners will get rid of evidence like bodies, blood, weapons, fingerprints, and even witnesses in order to hide the proof or notion of the crime -- or, they will 'dress up' the crimescene to mislead authorities. For example, they could make it appear like a break-in gone bad, an act of self defense, a fire, etc.
The cleaner used bleach to remove the the blood stains from the carpet, and although this would still leave DNA evidence, one could always claim that the victim once had a nose blead there... a very very massive nose blead!

Usually called upon to clean up a mess another mobster has made. For instance: a gangster robs a store one night and comes back to base with a bullet in his stomach. A cleaner is quickly called-up and will be sent in to clear any sight of evidence, even if this means killing the store-keeper.
Elite cleaners are rarely found in the mobs/mafias/gangs etc., but instead apart of a government agency. Considering the drastic consequenced often involved with these agencies actions, elite cleaners are required. You never hear of them, and you rarely hear of what they have cleaned up. All that's left is the event: something happened, but the cleaner will make sure there are no trails left behind. Such cleaning jobs can be on a global scale, such as clearing a trail of money used to get the job done.
Ricky and Paulie murdered Kalinsky in an elevator. As soon as they stepped off a cleaner stepped in. When the elevator chimed at the top floor all that was left of the scene was a dead body and a pool of blood. With no evidence for the police to go on, the killers were never found.
