I bought this as I got a new one month old Roborock 10r. Comparing these with the original, the feeling of the products (the roller brushes, the filter, and the bag) feel the same. These supplies should last six months or so, so the price is good for the value. The tip I will give is when changing the mop, PULL THE EXISTING ONE SLOWLY! There’s cheapish adhesive from the factory and can easily come off the Roborock.
