If you like using a couple of squeegees and a mop, then 3-TOOL is the best choice. What makes 3-TOOL so much better (apart from the price) is the Mop Cavity is in the center of the BOAB, so any 'over-run' from the mop scraping the sides, runs into the cavity on either side, not down the front of the BOAB.
