Update by user Feb 25, 2021 It hasn't developed at all. Original review posted by user Feb 23, 2021 I purchased a Mr. Clean mop for $10.00. Which I thought was expensive, but since it was a good brand name, or so I thought, I figured I'd give it a try. The mop immediately performed poorly. It kept coming apart at the head and would not stay attached to the pole no matter how I tried to rig it to do so! Finally, the piece just snapped which rendered the mop useless! The cheap bargain store mops that I used to buy lasted and performed much better and lasted longer! I am a loyal customer of Mr. Clean products, but this experience is making me rethink my loyalty! In short, I will never buy another Mr. Clean mop again!!! User's recommendation: Do not buy a Mr. Clean mop!!!
