Overall it's nice to have these replacement parts. A few issues: 1. The included tiny plastic-handled screwdriver snapped in half right away when we used it to remove some screws from the unit. 2. The screwdriver isn't the right size for some of the screws. It would be nice to have 2 sizes, both sturdier than the original. 3. The cleaning tool (see pic) has a square shaped end, instead if a tapered end like the original. This means you can't use it to clean the end notches on the main brush. 4. One of the main brushes doesn't fit well, and causes a horrendously loud noise when we tried it. The second brush is as quiet as the original.

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.
