SuperBee364- Thanks for posting that!
I've gone through three Karchers (two electric and one gas) and got so fed up with the lack or reliablity that I've done without one for the last few years. I'll keep all your info in mind when (not "if"

) I decide to buy my next one.
Good luck with the new wash regimen. Be very gentle with that BHB, don't scrub so hard that you really bend the bristles. And rinse it out thoroughly and often.
