Osmo Color Osmo Opti-Set Maintenance ① Mop ② Dust Mop (Green) ③ Cross Fiber Cloth (White) ④ Active Fiber Cloth I was using it to clean the floor with Osmo Wash detergent after dry wiping. I cleaned the mop every time I used it, so there is no noticeable dirt. Because it's a dedicated mop, it fits well and is easy to clean. You can maintain the floor without bending over. If anyone is interested in using it, please let me know ☺︎
