La tête d'aspiration comprend un ventilateur à flux transversal qui peut tourner autour d'un arbre rotatif, de manière à projeter de l'air sur la surface à nettoyer. La tête d'aspiration comprend un boîtier fixe cylindrique dont l'axe cylindrique est l'arbre rotatif, de sorte que le ventilateur à flux transversal puisse y être inséré. La tête d'aspiration comprend un boîtier rotatif cylindrique, qui comporte une sortie d'air par laquelle l'air projeté par le ventilateur à flux transversal est évacué, et qui peut tourner autour de l'arbre rotatif situé entre le ventilateur à flux transversal et le boîtier fixe.
