Fits and works the same as the original
Color: 6pcs
I like to change my washing pads on the Eufy C20 every Friday (floors are vacuumed Mon, Wed, Fri and get washed on Mon and Fri as well). I will send the mop out too just to do the kitchen once I have had a big cooking session. These fit well and work as well as the original. I'm so happy to have extras as my laundry sometimes take several days to get caught up. Recommended.

Poor quality
Color: 12pcs
I ordered these for my Eufy robot mop/ vacuum. While they fit great they are of terrible quality. They shredded on the first use and I have tile floors. Maybe I got a defective batch but I will not be buying these again🫤
