The problem is accurately perceiving the remaining snow/ice coverage on the airplane, unless you have a guaranteed-clear-on-first-pass solution (you don't). Sure, you can get it "mostly" clear with current CV, but you have to be absolutely clear or serious incidents will result (some aircraft suffer significant aerodynamic consequences from ice less than 1mm thick). Neither airport operators nor airlines will seriously consider a robotic solution unless it outperforms human operators, and the potential liability is high barrier to entry.
