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