An apparatus for automated maintenance of limited-access areas on large structures. The apparatus is a rolling or sliding tool-equipped mobile platform that is adhered to a surface by operation of one or more adherence fans and then propelled across the surface by operation of one or more propulsion fans. The adherence and propulsion fans are coupled to a base made of semi-rigid material. The adherence fans produce suction forces in one or more suction zones to adhere the mobile platform to the surface. The propulsion fans produce thrust to propel the surface-adhered mobile platform in a desired direction across the surface. The tool-equipped mobile platform is capable of adhering to and moving over a non-level surface on a large structure while keeping standoff contact elements in contact with the surface regardless of surface contour. The propulsion fans, adherence fans and maintenance tool (e.g., an NDI sensor unit) are controlled by a computer system.
