This BUXEBUX 23‑piece accessory kit fits the Eufy C20 Omni perfectly and has everything needed to refresh the vacuum without hunting for individual parts. The brushes, filters, and rollers all feel well‑made, install easily, and noticeably improve cleaning performance. Great value for keeping the robot vacuum in top shape.

Get the OEM mop cloths

Size: normal

When buying accessories for my eufy robot vac, I originally got my hands on some dupe accessories because they were cheaper. However- the mop cloths did not work well. The cheap construction of the dupes caused threads to constantly come out and get tangled, causing the robot to error out. I got these OEM ones and they work MUCH better. In this case it's best to buy the OEM parts even though they are more expensive!
