Incorrect filter size despite listed compatibility
I bought this kit specifically because the listing clearly states that it is compatible with my Xiaomi robot vacuum. Before purchasing, I double-checked all the specifications. However, when the product arrived, I discovered that the internal filter is smaller than the original one and does not fit correctly.
This makes the filter unusable for my vacuum. The seller should update the compatibility information because it is misleading for buyers.

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!
