IG-88 does look like a hard arsed piece of military kit though (much more than the battledroids in the PT do), I can't really visualise it cutting lawns or cleaning windows.

It's only really a concern for people who have seen the film so many times that they notice stuff like this.

Guilty! It's a trade-off I have to live with. Oh well.

But yeah, I don't really have a problem with some droids looking less metallic, but the IG-88 models do LOOK like they are made to do more physical things then mopping floors or interpreting languages, so it just seems like it should look more durable than it does currently.
