With regards to the hose, there is limited value in trying to ground something that is not conductive. You can’t usefully ground plastics unless they are deliberately made to be slightly conductive or ‘anti-static’. If you could then plastic insulation on mains wiring would not be very useful.
Wherever possible I use a proper anti-static hose;
These don’t just have a metal wire running through them, they contain a conductive material in the mix of the plastic. This is just enough to allow the static charge to be drained away easily to the wire, which you then ground to drain all the charge away.
I made sure my Shapeoko was well grounded;
I use an anti-static hose from my cyclone to the dust hood on the spindle, this is grounded at the spindle end because the Shapeoko is where my star-ground is located.
I have not bothered using anti-static between the vacuum and the cyclone, it’s not given me any trouble so far.
