Great quality dust bags – perfect fit for my eufy robot vacuum!
Size: C10 / C20 Bags
These dust bags are exactly what I needed for my eufy Omni C20! They fit perfectly, install easily, and the 3-layer design really does help control dust and odors. The large 3.6L capacity means I don’t have to change them too often, even with daily vacuuming. Great value for the price, and the quality feels just as good as the original eufy bags.

Fits Eufy Vaccum
Size: C10 / C20 Bags
Does fit my basic self emptying Eufy. Have to move it around a bit to get it to recognize the bag, but it does fit!

Doesn’t fit
Size: C10 / C20 Bags
Same exact things happens to me of this review — If you have an Omni C20, don't bother with these. They do not fit. The cardboard is too small and it keeps tripping the sensor that detects the bag when I put the cover back on. I've tried multiple bags in the set and they all do the same thing. Now to go find the place to report this listing for false advertising so maybe other people won't get scammed like me and others in the comments have.
