Perfect combo replacement parts.
These replacement parts fit my Eufy C10 without any issues and were easy to install. Everything snapped into place just like the original components, and I did not need any tools or adjustments. It was a quick refresh that had the vacuum back to normal cleaning right away.
The main brush feels sturdy and does a good job picking up debris without getting tangled too quickly. The side brushes spin smoothly and reach edges and corners well. I also noticed that the filters fit securely and do not feel flimsy, which helps maintain suction and keeps fine dust contained. The dust bags are well made and install cleanly without gaps or leaks.
After replacing the parts, the vacuum runs quietly and cleans more efficiently, especially on hard floors and along baseboards. It feels like routine maintenance that actually makes a noticeable difference in performance rather than just a cosmetic swap.
Overall, this is a solid replacement kit that matches the original parts well. It is a convenient way to keep the robot vacuum running smoothly and is a good option if you want reliable performance without hassle.

Practically 1:1
This kit is pretty much the same quality you would expect if you ordered directly from Eufy, excepting the HEPA filters which are *slightly* larger, and kind of weak compared to the originals. Aside from the filters, though, these are all very high quality parts, and practically indistinguishable from anything you would get directly from the manufacturer.
I went all in with these and replaced all of the original parts with these in one go a few weeks ago and the C10 is performing just as well as it did with the original parts. The size is spot on, the roller brush has the exact same functionality (unlike the ones I had ordered in the past for my 15C which scuffed up the unit), and the dust bags are functioning just like the originals, as well. I stuck the included cleaning brush off to the side in the base, and I use it to clean the unit every time I clean the HEPA filter.
Honestly, you really can't beat this value, these are great quality, and so much cheaper than the original parts.

Great Value Replacement Kit for Eufy C10
I recently picked up the Eufy C10 robot vacuum and absolutely love it, so I was excited to find this accessory kit. This is a much more economical way to stock up on all the wear-and-tear parts your robot needs. Everything fits perfectly, the quality feels solid, and it includes all the essentials—main brush, side brushes, filters, and disposable dust bags. Having these on hand makes maintenance easy and keeps the vacuum running at peak performance. If you own a Eufy C10, this kit is a no-brainer.
Pros
• Excellent value compared to buying parts individually
• Includes all common replacement items
• Fits the Eufy C10 perfectly
• Good build quality on brushes, filters, and bags
• Easy snap-in replacement with no tools required
Cons
• None so far
Verdict
A smart and affordable way to maintain your Eufy C10. Everything you need in one kit, good quality, and great peace of mind. Highly recommended.

Complete Kit at a reasonable price. Fits my Omni S1 Pro!
Color: Omni S1 Pro Accessories kit(14 Pieces)
I love my Omni S1 Pro robotic vacuum. Being able to get a complete resupply pack for my vacuum is wonderful. The whole kit at the coupon value is very reasonable.
The mop roller and brush fit my Omni S1 Pro robotic vacuum with no issues. The bags slide right into the charger base and are detected like my other bags I use.
Very pleased with the kit will order again
