    • A support assembly for a surface treating appliance includes a roller having one or more tires, wherein the one or more tires are fused to the roller. The roller can include a polymer such as polypropylene and may also include a glass filled impact modified copolymer such as a 20% glass filed impact modified copolymer. The tires can include a thermoplastic elastomer such as a modified polymer including a mixture of polypropylene and an ethylene propylene diene monomer. The thermoplastic elastomer may have a hardness of from 55 to 95 Duro measured on the A scale, more specifically from 70 to 79 Duro on the A scale or from 80 to 95 Duro on the A scale.
    • 用于表面处理设备的支撑组件包括具有一个或多个轮胎的辊,其中所述一个或多个轮胎与辊熔合。 辊可以包括聚合物如聚丙烯,并且还可以包括玻璃填充的冲击改性共聚物,例如20%玻璃冲击改性共聚物。 轮胎可以包括热塑性弹性体,例如包括聚丙烯和乙烯丙烯二烯单体的混合物的改性聚合物。 所述热塑性弹性体可具有在A刻度上测得的55至95Duro的硬度,更具体地,在A刻度上为70至79Duro,或在A刻度上为80至95Duro。

    • A cleaning appliance includes a main body, a handle assembly and a hose. The handle assembly includes a tube and a gripping portion fixedly attached thereto. The hose has one end attached to the main body. The tube is movable relative to the main body between a stored position in which at least a part of the tube lies within the hose and an extended position in which the gripping portion can be used to manipulate the cleaning appliance in use. By providing such an arrangement, the handle assembly and the hose can be stored compactly. When the user wishes to store the cleaning appliance, the tube can be retracted inside the hose for storage. When the tube is extended, the gripping portion is at a convenient height to be manipulated by a user.
    • 清洁器具包括主体,手柄组件和软管。 手柄组件包括管和固定地附接到其上的抓握部分。 软管的一端连接到主体。 管可相对于主体移动到存储位置之间,其中管的至少一部分位于软管内,并且延伸位置,其中夹持部可用于在使用中操纵清洁器具。 通过提供这样的布置,可以紧凑地存储手柄组件和软管。 当用户想要存储清洁器具时,管可以缩回到软管内用于存储。 当管延伸时,抓握部分处于由用户操纵的方便的高度。
