APPARATUS FOR CLEANING A SURFACE

The apparatus (100) for cleaning a surface (210) comprises a housing (300) for accommodating an object (200) whose surface (210) is to be cleaned, a wiper driving actuator (400) adjacent the surface (210) to be cleaned, the wiper driving actuator (400) comprising an at least partially closed loop (410) adapted to rotate about a longitudinal axis (y) of the housing (300), and at least one wiper assembly (500) operable by the wiper driving actuator (400) to move along the at least partially closed loop (410) and having a first end (510) that is attached to the wiper driving actuator (400), the wiper assembly (500) being movably mounted in the housing (300) such that, in use, a constant distance is kept between the wiper assembly (500) and the surface (210) to be cleaned. 用于清洁表面(210)的清洁器具(100)包括：用于容纳其表面(210)待清洁的物体(200)的壳体(300)；邻近待清洁的所述表面(210)的擦拭器驱动致动器(400)，该擦拭器驱动致动器(400)包括至少部分闭合的环(410)，该至少部分闭合的环(410)适于围绕所述壳体(300)的纵向轴线(y)旋转；以及至少一个擦拭器组件(500)，该擦拭器组件能由所述擦拭器驱动致动器(400)操作而沿所述至少部分闭合的环(410)移动，并且该擦拭器组件(500)具有附接至所述擦拭器驱动致动器
