An automated (robotic) floor cleaner (100) is adapted to allow sterile cleaning of sensitive environments, such as hospital room. In particular, the floor-cleaner chassis (124) is redesigned to be mounted on a deck (102) containing cleaning devices that contact the floor. The cleaning devices mounted on the deck (102) include vacuum head (132), brushes (120), cleaning fluid sprays (128), and conceivably sanitizing devices such as UV germicidal light, are provided pre-sterilized. As such, the adapted floor-cleaner chassis (124) allows the deck (102) to be mounted to the bottom of the chassis (124), the floor-cleaner (100) is then used to clean a floor, after which, the deck (102) is removed from the chassis (124) and disposed. The robotic-floor cleaner (100) and sterilization system cleans floor between or even during cases. Further, the robotic floor cleaner (100) reduces the &ldquo；turnover time&rdquo； required between cases, as it operates simultaneously while the staff prepares the room for the next case.
