I was trying to avoid complex mechanisms in fans to clean such as polarity swapping and dust judder shake mode.

How about blades that when dirty are swapped. The surface would be designed to attract and contain as much dirt as possible. These would be made similar to one of the commercial dust wipes on the market in an air pushing shape.

Of course the fan would have to be made in such a way as to be easy opened, dismantled and to replaced the blades. Ohh and probably cleaned.

This would be good for ceiling paddle fans [+].

//the air has to come out somewhere.//

This is not true for vacuums of sufficiently large sizes
