It is because electric charges in the dust and surfaces attract each other. A duster works by generating static electricity and causing the dust particles to stick to the hairs.
I did a quick look for something that rejects dust with electricity and here is electrostatic dust repulsion for solar panels to reduce washing intervals https://pmc.ncbi.nlm.nih.gov/articles/PMC8916732/ So maybe we could get this in our walls and make everything easier to clean.
