Much better option is just to add high intensity UV lighting to sterilize the AIR and most surfaces. For deep cleaning there are plenty of more or less mechanical solutions that are next to impossible to evolve around.
In some hospitals they have rolling columns of UV lights that they leave in rooms after chemically cleaning them to provide an extra cleansing effect and also reduce airborne transmission of disease.
I've read interesting research that suggests that subjecting surfaces to ultrasound discourages the development of biofilms. This also helps cleaning.
