Get yourself a spare set of mop cloths to keep your Roborock always ready to run
Size: Mop Cloth-5
Does the Roborock do a fantastic job mopping the floor? No, but it does a pretty good job, in fact “good enough.” Even better, the Roborock mops the floor more frequently than I ever did so it stays cleaner, overall. Definitely get a pack of spare mop cloths so you can have a set being washed while another set is available to put on the mop. So far, none of the mop cloths have worn out. Given how long they’re lasting, I’m inclined to say it is a decent value for the price paid.

OEM Roborock Cleaning Pads - Do not buy the knock offs.
Size: Mop Cloth-4
These are Roborock OEM pads for my 10R. I tried many of the cheap knock offs and they were terrible. These work great. Highly recommend.

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.
