Good Value Replacement Kit for Eufy C20
This accessories kit for the Eufy C20 Omni Robot vacuum includes everything listed in the description. The 8 mop pads are consistent in size and shape. They aren’t quite as thick as the original pads that came with the unit, but they fit well and give me a good supply of clean replacements. With dogs in the house, my Eufy is running almost daily, so that’s a big plus.
I haven’t used the other components yet since I had just replaced the bag and cleaned the filters before ordering. I’ll update my review if anything doesn’t fit as expected. For now, I’m comfortable giving this 4 stars — and if 4.5 were an option, that’s what I’d choose. This seems like a solid budget-friendly alternative to the OEM Eufy replacement parts.
