摘要： A cleaner head (20) for a vacuum cleaner (2), the cleaner head comprising: a housing (32) defining a suction chamber comprising an outlet (34); and an agitator element (22, 24) being mounted for rotation about an axis (R1, R2), wherein: the agitator element comprises a first, free end (26a, 26b) and a second end (28a, 28b), the agitator element has a shape which tapers towards the first end in a direction along the axis of rotation, the agitator element is cantilevered from a portion (30) of the cleaner head at the second end, and the housing comprises a side opening (36) in the housing, adjacent the first end of the agitator element.

摘要： 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, wherein 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 the position of the axis at the first end of each agitator element is further forwards than the position of the axis at the second end of each agitator element.
