The document discusses aircraft washing robots called Nordic Dinos that are manufactured by Aviator to clean commercial and military aircraft. It describes three models - Nordic Dino 777+ designed for wide-bodied aircraft like the Boeing 777, Nordic Dino II for narrow-bodied aircraft, and Nordic Dino 4380 for the Airbus A380. The robots use a mobile power unit, spray nozzles and rotating brushes that are operated remotely to efficiently and safely clean aircraft exteriors. Having a clean aircraft provides benefits like lower fuel costs, extended paint life, and safety. Over 100 units have been sold worldwide.
