Not a 9X0 owner yet, but I'm not sure I understand the benefit. Backflushing the filter, so all the debris that was caught in it goes back into the tank, only to be sucked into the filters again once it all settles back out? What am I missing? Have read a lot on clogged filters, but it seems that a backflush would only slightly delay the inevitable, as the crud is still there?
I've gotten old enough to enjoy the journey, and not just the method of travel.
