For neutralisation of static bond, the best pre-treatment would be a cationic surfactant such as Ultrapac Renovate (1:20 or even 1:30).
After a 15 minute dwell, a good treatment with the Host machine with white or zebra brushes would be my choice. One of the advantages of the Host is that there is a narrow gap between the brushes where the fluff collects, whereas the Sebo Duo has brushes that are set further apart and the base-plate prevents the fluff entering the machine.
