There’s a definite quality difference between the OEM product and third party knock-offs
Size: Mop Cloth-4
It’s worth getting replacement parts for your vacuum from the manufacturer. These pads are high quality. I purchased some third party ones and they fell apart after a week of use. It’s worth the extra money to have something that will last for many months when properly cared for.

Overpriced but works
Size: Mop Cloth-4
Easy replacement, tear off and slap on. Can’t really go wrong. Fit is perfect. Floors started to get feel consistently again. I feel like this product is definitely overpriced for what it is.
