hi there,
wonder if anyone can answer this for me, recently my float ball in the waste tank is being sucked up when we turn on the second vac, with a completely empty waste tank.
when we aquired the machine second hand last year gave the filter in the waste tank a good and thorough clean, and it is still clean,
So i 'm wondering if there are any other filters in the vac motors that need to be looked at.
weird thing is, that if you put the second vac on after a couple of inutes use then everything is fine,
regards
martin.
