Abstract
A method to automatically remove obstructions, such as electrical cords or wires, from robotic floor-cleaning devices after becoming entangled with wheels of the robotic device during operation. Upon sensing entanglement with an obstruction, the robotic floor-cleaning device is configured to retract one or more wheels into a wheel housing within the main housing of the robotic device. During retraction, the obstruction entangled around the one or more wheels is forcibly separated from the wheel by the corresponding wheel housing.
