Here is one model, our M8540 has the AC slide out AC further further back in the engine compartment. We clean ours with compressed air blown through the rear of the screen. We have a 2' extension with out let holes in the side of the wand or one with and angled end to make access easier.
You also have an inlet cab filter that we replace yearly and one behind the seat that just requires cleaning.
