These mop heads are a fraction of the cost of the heads we have used for years and work just as well—and in some aspects, even better. These are not “washable” as the previous heads were, but realistically they wore out and frayed before ever making it to the point of needing anything other than a soak in disinfectant, so that isn’t very important when it comes to a daily-use mop. These appear to be constructed well and look as though they will last an acceptable amount of time. They are extremely light when soaked, but oddly this doesn’t seem to be an issue as it remains stacked in use, is extremely absorbant, and has perfectly-placed webbing that makes them extremely versatile for whatever mopping style is needed. While we can’t speak for the actual durability—yet—the price per unit negates that concern.
