    • A tool (10) for a surface treating appliance comprises a main body (12) connected to a conduit (14). The main body (12) comprises a first suction channel (22) and a second suction channel (24) in fluid communication with the first suction channel (22) and located between the first suction channel (22) and an outlet from the main body (12). In use, a relatively low vacuum is generated in the first suction channel (22) which draws a first dirt-bearing fluid flow into the main body (12), and a relatively high vacuum is generated in the second suction channel (24), which draws a second dirt-bearing fluid flow into the main body (12) and receives the first dirt-bearing fluid flow from the first suction channel (22). To maintain the pressure differences between the suction channels (22, 24), the main body (12) comprises flexible surface engaging means (32, 34) located about the suction channels (22, 24), and between the first suction channel (22) and the second suction channel (24).
    • 用于表面处理设备的工具(10)包括连接到导管(14)的主体(12)。 主体(12)包括与第一抽吸通道(22)流体连通并且位于第一抽吸通道(22)和来自主体的出口之间的第一抽吸通道(22)和第二抽吸通道(24) (12)。 在使用中,在第一抽吸通道(22)中产生相对较低的真空,其将第一含尘流体流动流入主体(12),并且在第二抽吸通道(24)中产生相对高的真空度, 其将第二含尘流体流动到主体(12)中并且接收来自第一吸入通道(22)的第一污物流体流。 为了保持吸入通道(22,24)之间的压力差,主体(12)包括围绕抽吸通道(22,24)定位的柔性表面接合装置(32,34),以及位于第一吸入通道 )和第二抽吸通道(24)。
