After about 2 months of daily cleanings, the side brushes were looking a little ragged on my Eufy 12. The brushes included in this kit did come out a little bent, but as shown on the product page, when I dipped them in hot water they straightened right out. Intrigued, I decided to try that with the original brushes. They cam out looking like new! The only con is that the filters don't look like a perfect fit. The foam seems very minutely smaller than the original and the pleated filter seems slightly thicker.

All items fit the Eufy 30C perfectly.

Style: 19 Pack

We bought a Eufy 30C several months ago. After each time it is run, I clean the dust collection chamber, brush dust out of the filter and from the sponge-like pre-filter. After several uses, the filters simply were becoming clogged with tiny dust particles. This kit holds 10 filters and pre-filters, 8 brushes (or four sets) and one main roller brush. Every piece fits perfectly. They look and feel like original quality materials. This is a great set of replacement parts to keep your Eufy working like new.

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.
