An autonomous floor cleaning robot (100) includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone (A) comprising cleaning elements (600) arranged to suction loose particulates up from the cleaning surface and a second cleaning zone (B) comprising cleaning elements (700) arraigned to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis (200) carries a supply of cleaning fluid and a waste container (D) for storing waste materials collected up from the cleaning surface.
