Essential!
Style: 19 Pack
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.

Works great, easy to setup. It's my second unit for the basement level. Picks up all the fur from a large Rottweiler and a small Rat Terrier.
