The invention provides an accessory (10, Fig 1) for a cleaning appliance having a head (12) comprising a housing (24, Fig 2) and a downwardly-directed suction opening (16, Fig 2) and a neck (22; 122) adapted for attachment to a hose or wand of the cleaning appliance. A rotatable connection (28, Fig 1) is provided between the neck (22) and the head (12) for allowing rotation of the neck (22) relative to the head (12), and a wheel arrangement (30) is provided for manoeuvrably supporting the accessory (10) on a surface to be cleaned (40). The wheel arrangement (30) is mounted on the neck (22) of the accessory. In a preferred embodiment, the wheel arrangement (30) is normally in contact with the surface to be cleaned (40) but the point or points of contact between the wheel arrangement (30) and the surface to be cleaned (40) are dependent upon the rotational position of the neck (22) with respect to the head (12). |
