ABSTRACT OF THE DISCLOSURE An integral, one piece shoe attachment for detach- able insertion in the intake orifice of an electric vacuum cleaner. The bottom surface of the shoe attachment has rounded projections which raise the shoe attachment bottom surface slightly off the surface being suctioned. A flex- ible blade extends along the long dimension of the inlet opening and divides the inlet opening into a front and rear section. The blade projects down far enough that as the shoe attachment is moved in one direction, the blade flexes to close off one section of the inlet opening, and as the shoe attachment is moved in the opposite direction, the blade flexes in the opposite direction to close off the other section of the inlet opening.
