A floor cleaning system and method for use thereof is disclosed for facilitating removal of waste materials. The system includes and the method relies upon use of a floor base, a floor covering, a substrate spacing the floor base and the artificial grass surfacing apart from one another, and at least one fluid-carrying structure. The floor base receives the waste materials. The floor covering is spaced above the floor base, and is at least in part permeable to the waste materials and in liquid communication with the floor base. The fluid-carrying structure is adapted to provide cleaning fluid to the floor base to rinse the waste materials received thereon. The cleaning fluid and waste materials flow along the floor base under the floor covering to facilitate evacuation thereof.
