Debris removal systems and methods are operable to remove debris, such as snow, from a surface. An exemplary embodiment has a wiper blade configured to remove debris from a surface in response to a movement of the wiper blade; a spring coupled to the wiper blade, wherein the spring is configured to store potential energy as the spring is biased from a relaxed position to a biased position; and a motor coupled to the spring, wherein the motor is configured to convert received electrical power into mechanical power that biases the spring. The spring is released from the biased position to release the stored potential energy as the spring returns to the relaxed position. The released potential energy from the spring is converted to mechanical energy that moves the wiper blade.
