Full microfiber - with full wiping surface, premium quality. They are just as wide (30 cm as the original version). Advantage of these towels is not only the price, but Premium quality, thick and soft on the wiping side, but always firm inner background (the firmer the better the wiping), same size as the original one on your Roborock, stitched very accurately. The floor gets 97-100% wet, and after multiple machine washes (over 40 times so far) they stay put vacuum wiper just as great as at the beginning. the white velcro from the back is just as thin as it should be so wipes the entire surface from the wipe. Some manufacturers use Velcro that is 1 mm thicker than the original mop... The result of this is that only the 2 cm of the entire wipe is used on the edge, from the outside of Velcr.
