Abstract
A suction head for a vacuum cleaner comprises a hollow body including a pair of arms (1, 3) which diverge from predetermined region of the body at an acute angle. Each arm is formed with a channel (14) for the passage of air. 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). A second continuous ground-engaging barrier (21) extends along the region of an inner edge (19) of the other of the arms (3). A gap (23) is formed between the first and second barriers (21) for the passage of relatively large particles of debris into the suction head.
