The disclosure relates to an automated steam-based vehicle cleaning system and method. The system includes a steam generator, a multi-axis robotic arm equipped with a steam nozzle, a steam distribution manifold, and an air delivery system for drying. A three-dimensional imaging system, comprising overhead and side-mounted sensors, generates detailed representations of vehicles within the cleaning chamber. A controller, integrated with the imaging system and robotic arm, processes the imaging data through a machine learning algorithm for object detection and localization. The control unit orchestrates the operation of the steam generator, robotic arm, and other components based on the processed data, ensuring precise and efficient cleaning. The method involves generating a three-dimensional model of the vehicle, detecting and localizing the vehicle, determining an optimal cleaning path, and executing the cleaning process with real-time adjustments, followed by a drying phase using forced air.
