haha, that's how I feel about my dyson. I may scrap it, you've inspired me.
On my lam wood floors I use the dyson, but then pnce a week, a damp mop with one of those long pad type mops. I don't know what its called but it is long and a rectangle with a soft terry cloth removable thingy. That's what the guy told me to use. I bought mine at the grocery store. Oh and for spot cleaning I use Mr Clean Magic Eraser, for when the little one colors on the floor with crayon.
