用于清洁器具的吸尘附件，可灵活转向。
专利摘要
一种用于清洁器具的附件包括具有壳体的头部、壳体中的向下指向的吸入口和适于连接到清洁器具的软管或吸尘杆的颈部。在颈部和头部之间提供可旋转连接，以允许颈部相对于头部旋转。轮装置可操纵地将附件支撑在待清洁表面上，并安装在附件的颈部上。轮装置通常可以与待清洁表面接触，但轮装置与待清洁表面之间的接触点取决于颈部相对于头部的旋转位置。
Original abstractAn accessory for a cleaning appliance includes a head having a housing, a downwardly-directed suction opening in the housing and a neck adapted for attachment to a hose or wand of the cleaning appliance. A rotatable connection is provided between the neck and the head for allowing rotation of the neck relative to the head. A wheel arrangement maneuverably supports the accessory on a surface to be cleaned and is mounted on the neck of the accessory. The wheel arrangement may normally be in contact with the surface to be cleaned, but the point or points of contact between the wheel arrangement and the surface to be cleaned are dependent upon the rotational position of the neck with respect to the head.
