Because neither the grate or window-screen are smooth surfaces. A suction cup (or similar device) needs a smooth, non-porous surface in order to form an air-tight seal.

Why do suction cup stick to wet surfaces better than dry surfaces?
No. How well a suction cup sticks to a surface has to do with how will a seal can be formed on the surface. Rough surfaces will not form good seals compared to smooth surfaces which means that suction cups will not stick as well to rough surfaces as they do to smooth surfaces.
What will happen if air enters the inside of a suction cup?
The suction cup will lose its attachment, unless it has an additional adhesive. Suction cups attached to a surface are held there by the pressure of the outside air, which is higher than the pressure under the cup. The suction cup is trying to return to its uncompressed condition, and pulls away from the surface, reducing the pressure under it.
