Hands & knees here to, most usually... Mops suck.. you gotta get it wet, wring it out..... it doesnt seem to get clean like a good ol' hand scrubbin'
I did however JUST TODAY buy me a "Orange Glo Hardwood floor" swiffer type deal for my hardwood flors... which is alot. I have been hands & kneein' it til now... I will see if this works or not... If not... back to hands & knees.

annnnndd. I will definately invest in some knee pads cause it KILLS my knees
