The stair-climbing wheeled carrier has a U-shaped frame defined by a pair of elongated parallel handles and a crossbeam extending between the ends of the handles. Each handle has an axle mount depending therefrom having a star wheel or spider wheel mounted thereon. A dual shaft worm drive motor is mounted on the frame, the shafts driving chain drives connected to the wheels. A throttle extends from one of the handles, and controls leaf springs that operate switches for actuating the reversible motor and returning the throttle to neutral when released. A payload is attached to brackets mounted on the handles. The payload may be a seat for a person needing assistance attending/descending stairs, or a basket for carrying packages or other items upstairs. In use, an assistant uses the handles to support the frame while operating the motor to activate the wheels for climbing stairs.
