Review on Optimized for Search: Libman 3021 Gator Mop Refill, 9" by Michelle Marsden

For the time being this replacement Gator mop sponge seems to be just as durable as the original sponge. I've been using it for several months and it's held up well. It looks like replacement sponges for this mop model are not available in store so this is where you can get them. Update: The sponge lasted about 5 months and then started falling apart so it's not as strong as the original. I've gone through a few of these already, and the second one ripped it up after a while, leaving bits of sponge on the floor. The pack says it lasts for 50 uses, but that's closer to the 20-25 I've found. They're still way better than buying a new Gator mop.
