These mop heads pick up dirt very well. In fact, when I first used it - I made an entryway and a small section of floor leading into the living room and for a smile I turned my head to see how it worked and was so amazed at how much There was dirt on it - I took a picture so I was able to add it when I did the review. But for some reason I can't attach a photo. It's just my husband and I here so the floors don't get that dirty. The gray zigzag is made up of olefin that really erases. They fit great too. Very impressed and will buy again.
