Ensemble d'essuyage magnétique permettant d'essuyer librement sans séparation et utilisé pour nettoyer une fenêtre d'observation, et procédé de conception de l'ensemble d'essuyage magnétique. Un élément d'essuyage interne est utilisé pour essuyer une surface interne de la fenêtre d'observation ; un élément d'essuyage externe coulisse sur une surface externe de la fenêtre d'observation ; l'élément d'essuyage externe tire, sur la surface externe de la fenêtre d'observation par force magnétique, l'élément d'essuyage interne sur la surface interne de la fenêtre d'observation pour qu'il se déplace en suivant l'élément d'essuyage externe ; l'élément d'essuyage externe est relié à un élément portatif externe ; la force de liaison entre l'élément d'essuyage externe et l'élément portatif externe est bien inférieure à la force d'attraction magnétique entre l'élément d'essuyage externe et l'élément d'essuyage interne, et, lorsque la force externe appliquée à l'élément portatif externe est supérieure à la force de liaison entre l'élément d'essuyage externe et l'élément portatif externe et que la direction d'action de la force externe est opposée à celle de la force de liaison entre l'élément d'essuyage externe et l'élément portatif externe, l'élément d'essuyage externe est séparé de l'élément portatif externe, et, dans le même temps, l'élément d'essuyage externe et l'élément d'essuyage interne ne sont pas séparés en raison d'une attraction magnétique réciproque. L'attraction et la traction entre l'élément d'essuyage externe et l'élément d'essuyage interne peuvent encore être assurées sous l'action d'une force externe, et la situation dans laquelle l'élément d'essuyage externe est séparé de l'élément d'essuyage interne en raison d'une force externe irrégulière est évitée.
