I've owned quite a few mops over the years. I was ecstatic back in the day to get to trade in my old-fashioned sponge-type mop for the new Swiffer one. It was so handy, so quick and so much less icky.
But then, as I kept having to buy new pads and new spray stuff, over and over, I began to see the ridiculous outlay of cash it truly required. So, I saved up a little money and bought the Bona mop for wood floors. It had a washable pad and no spray thingy at all. I just had to put floor cleaner in a spray bottle with some water and spray by hand as I cleaned, tossing the pad in the wash afterward. I loved that I didn't have to keep throwing cash in the trash, literally. Alas, after a number of years it eventually broke.
