Perfect fit.
Fits perfectly in my eufy Omni C20. I originally bought some off brand bags, but the cardboard part for the opening was a tad bit too small. These however are perfect. They also come in a small box which is convenient for storage. If you have the eufy Omni C20, buy these. Skip the off brands.
