O-Cedar Easy Wring Rinse Clean Spin Mop 2-Tank System Refill Mop Head 810020412093 My brother bought the wrong style and didn't realize it until it wouldn't fit the mop. But since it was open he couldn't return it. This has never been used. It was immediately put back in the package after it didn't fit. ** fits the 2-tank system only - will not fit the 1-tank system
