    Abstract: A tool for a surface treating appliance includes a main body connected to a conduit. The main body includes a first suction channel and a second suction channel in fluid communication with the first suction channel and located between the first suction channel and an outlet from the main body. In use, a relatively low vacuum is generated in the first suction channel which draws a first dirt-bearing fluid flow into the main body, and a relatively high vacuum is generated in the second suction channel, which draws a second dirt-bearing fluid flow into the main body and receives the first dirt-bearing fluid flow from the first suction channel. To maintain the pressure differences between the suction channels, the main body includes flexible surface engaging members located about the suction channels, and between the first suction channel and the second suction channel.
