Mr. Janitor (Fallout: New Vegas)

"My, my. This place is filthy!"

 is a Janitorial robot found in the Sunset Sarsaparilla Headquarters.

Background
Mr. Janitor is a deactivated Mister Handy robot that is programmed to clean up the offices and shipping room area of garbage. He was loved by most of the staff for doing a better job than the old models of this type.

Other interactions
When activated by a terminal in the janitor's closet (50 Science required), he will roam around the bottom floor commenting on how dirty everything has gotten over "the past few days," and "this room is even dirtier than the last one!" Also appears to comment if the Courier approaches or kills another of the robots in his presence "What are you savages doing here?" before finally ending at a trashcan and shutting down back in janitor's closet.

Appearances
Mr. Janitor only appears in Fallout: New Vegas.
