A cleaner head for a vacuum cleaning appliance includes a housing which defines a suction chamber. The suction chamber has a suction inlet through which air enters the suction chamber, and a suction port through which air exits the suction chamber. The cleaner head includes a plurality of casters for supporting the cleaner head. Each caster is rotatable relative to the housing about a first axis which is perpendicular to the suction inlet. Each caster is also rotatable relative to the housing about a second axis perpendicular to the first axis. The cleaner head further includes a plurality of guide members for guiding into the suction chamber debris entrained within air drawn towards the suction inlet. Each guide member is arranged to rotate with a respective caster about the first axis.
