TOOL FOR A SURFACE TREATING APPLIANCE
First Claim
1. A tool for a surface treating appliance, comprising a main body connected to a conduit, the main body comprising:
- a first suction channel for receiving a first dirt-bearing fluid flow; and
a second suction channel for receiving the first dirt-bearing fluid flow from the first suction channel and a second dirt-bearing fluid flow, and for conveying the dirt-bearing fluid flows to the conduit;
wherein the first suction channel and the second suction channel are at least partially defined by flexible surface engaging members, the flexible surface engaging members comprising at least one first flexible surface engaging member located about the suction channels and at least one second flexible surface engaging member located between the suction channels.

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.
