A suction head for a vacuum cleaner comprises a hollow body including a pair of arms which diverge from a predetermined region of the body at an angle less than 180 degrees relative to each other. Each arm is formed with a channel for the passage of air, the channel extending from the free end of the arm to the region of the body from which the arms diverge. An outlet opening is located in the region of the body from which the arms diverge for the passage of air to a vacuum cleaner. A first continuous ground-engaging barrier extends along the region of an inner edge of one of the arms from the free end of the arm to the region of the body from which the arms diverge. A second continuous ground- engaging barrier extends along the region of an inner edge of the other of the arms from the free end of the arm to the region from which the arms diverge. A gap is formed between the first and second barriers in the region from which the arms diverge for the passage of relatively large particles of debris into the suction head. The first and second barriers are adapted to engage a flat ground surface along the entire length of the first and second barriers.

Un bec d'aspiration pour aspirateur comprend un corps creux comportant une paire de bras qui divergent à partir d'un endroit précis du corps selon un angle inférieur à 180° l'un par rapport à l'autre. Chaque bras est pourvu d'un canal prévu pour le passage de l'air, lequel canal s'étend de l'extrémité libre du bras jusqu'au point de raccordement des bras sur le corps. Une ouverture de sortie est aménagée dans la région du corps où les bras divergent pour le passage de l'air jusqu'à l'aspirateur. Une première barrière monobloc en contact avec le sol se prolonge le long de la bordure interne de l'un des bras, à partir de l'extrémité libre du bras jusqu'au point de raccordement des bras sur le corps. Une seconde barrière monobloc en contact avec le sol se prolonge le long de la bordure interne de l'autre bras, de l'extrémité libre du bras jusqu'au point de raccordement des bras sur le corps. Un espace est aménagé entre la première et la seconde barrières, au point de raccordement des bras, afin de laisser passer les particules de débris relativement grosses dans la tête d'aspiration. La première et la seconde barrières sont conçues pour balayer une surface de sol plate sur toute leur longueur.
