Regarding the static:
It was really giving me light shocks when touching the hose.
Might have been something in my setup, because until now I only experienced it once!
Setup was:
- small balcony, single power outlet inside, door almost closed behind me
- sanding with ETS EC 150/5
- on top of a Systainer stack (SYS-MFT brought up to working height)
- CTL-SYS as a Vac
So maybe the plastic of the Systainer stack or something else contributed.
It was just a small sanding job for a tiny table, so I just kept "grounding" the hose every so often, for the build up to be minimal.
Maybe the weather? Warm Summer day, ending in a nice summer-rain...
