A suction head for a vacuum cleaner comprises a hollow body including a pair of arms (1, 3) 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 (14) 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 (5) 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 (21) extends along the region of an inner edge (19) of one of the arms (1) from the free end of the arm to the region of the body from which the arms diverge. A second continuous ground-engaging barrier (21) extends along the region of an inner edge (19) of the other of the arms (3) from the free end of the arm to the region from which the arms diverge. A gap (23) is formed between the first and second barriers (21) 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 (21) are adapted to engage a flat ground surface along the entire length of the first and second barriers.
