They need to invent a literal dust magnet for cleaning...

you're familiar with the concept of an electromagnet, where electricity is applied to create a magnetic field.

consider the concept of a magnet for static electricity, and then take that further to be an electrostaticmagnet. push the button, activate the charge, attract dust and dirt and what not. push the button again, and a button to discharge the static, and things fall off into a collector.

i came up with that in high school.
