    Abstract: A cleaner head for a vacuum cleaner, the cleaner head being configured to apply suction to a horizontal surface to be cleaned by the vacuum cleaner. The cleaner head includes: first and second agitator elements each being mounted for rotation about a respective axis. Each agitator element includes a first, free end and a second end, each agitator element has a shape which tapers towards the first end in a direction along the axis of rotation, the first and second agitator elements are cantilevered from opposing sides of a hub portion of the cleaner head at their respective second ends, and each agitator element is arranged such that when the cleaner head is applying suction to the horizontal surface, the position of the axis at the first end of the element is closer to the surface than the position of the axis at the second end of the element.
