Abstract: A cleaner head for a vacuum cleaner having a suction inlet, a front blade and a rear blade. The front blade is located forward of or at the front of the suction inlet and is arranged to pivot about a first axis. The rear blade is located rearward of or at the rear of the suction inlet and is arranged to pivot about a second axis different to the first axis. Each blade pivots between a deployed position and a retracted position. The blades are configured such that when one of the blades is in the deployed position, the other of the blades is in the retracted position. Additionally, when one of the blades moves from the deployed position to the retracted position, the other of the blades moves from the retracted position to the deployed position.
