Quickie changed their mop but not the model number awhile ago and I ended up buying the wrong style for a bit for my workplace before we figured it out. Here are 5 mop heads--one is new in package, the other are out of package but unused. One looks a little dirty but just from storage not from actual use for gross things. 

One is  dense foam which may be past its prime and not work well for long. The others seems fine. 

Measure 9" long with attachment hole in middle. No screws or other pieces so if those are necessary, they are not included!
