The invention provides a cleaner head (100) for a cleaning appliance (10; 50) comprising a housing (102) having an upper surface (104) and an underneath surface (106) in which at least one suction opening (108) is arranged, the underneath surface (106) having opposing side edges (106a, 106b), each side edge (106a, 106b) comprising a first part (106c, 106d) which lies adjacent the suction opening or openings (108) and forms a sharply-defined edge with the upper surface (104) and a second part (106e, 106f) which is located rearwardly of the suction opening or openings (108). The second part (106e, 106f) of each of the side edges (106a, 106b) of the underneath surface (106) is upwardly curved. This arrangement is advantageously used in vacuum cleaners or other cleaning appliances in which a ball-type support allows an increased level of steerability involving lateral movement of the cleaner head (100) across the surface to be cleaned. The upwardly curved side edges (106e, 106f) of the underneath surface (106) of the cleaner head (100) reduce the amount of effort required to achieve the steering by presenting a smoothly curved surface to the carpet or other floor covering. At the same time, the first part (106c, 106d) of each side edge (106a, 106b) can be placed close to a wall or skirting board so that good edge cleaning is maintained. |
