An apparatus for cutting a window covering comprises a lateral support surface and a saw for cutting the window covering positioned at an end of the lateral support surface. An engagement member locates the center of the window covering that is retractably mounted on the lateral support surface. A clamp assembly comprises a clamping jaw that is movable to a first position where the clamping jaw presses the window covering against the lateral support surface. The clamp assembly is movable relative to the first saw and the second saw. A controller for moves the clamp assembly to automatically position a first end of the window covering relative to the first saw and a second end of the window covering relative to the second saw.
