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.

I love my MOVA P10 Ultra and I love that the accessories are reasonably priced. When you use it like I do, you will need the accessories over time. Having it all packaged together is very convenient!
