MUJI Floor Wiper Head only. I think it's clean and without stains, but this item has a defect. "There are comments that the height difference and grooves around the head (edge) make the center of the sheet lift easily when attached, and it tends to wipe dirt only with the edge." I saw the above comment online, and I used it after processing the edge by shaving it all around. Also, there is a missing part. The circled area. Please refrain from purchasing if you are concerned.
