Very poor quality items. Rotating brushes are cheap, used with inferior adhesive as they come out very easily. The roller seems used and cleaned to resell as it does a poor job. With all the items included it seems like a good deal, but the poor quality makes it not so. Do not recommend. I bought the items in late December 2022 and I just put my last rotating brush on already (Late March 2023).

Great bags for Eufy at a reasonable price!

Size: C10 / C20 Bags

Fits my Eufy vacuum as well as the original bag. Such a nice find, a good bargain, not cheaply made either- we are on our 3rd bag from this package and they’re holding up fine just like the original manufacturer bags.

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.
