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.

Not worth it
Style: L50 SES
Worked great for 5 months and then the WiFi connectivity stopped working rendering the vacuum useless. Because it’s refurbished it was past its warranty and the company refused to do anything about it other than offer a discount on a product that cost four times as much even after the discount.

Great vacuum, but it only works on 2.4 GHz Wi-Fi
Style: L50 SES
I missed the last line on the description that states in only works on 2.4 GHz Wi-Fi. I have AT&T fiber and the router they installed only runs on 5.0 GHz. The vacuum still works, but without all of the fancy conveniences. Just be aware of this and if you are not familiar with what it means, check before you purchase one. This is the only reason I am giving it a 4 and not a 5. It is my fault for missing it, so just be aware.
