My Eufy C10 Feels Brand New Again—And It’s Cleaning Like It’s Trying to Impress Someone
If your eufy C10 has been sounding like it’s working but not really working, this replacement parts kit is the reset button you didn’t know it needed. After swapping out the filters, brushes, and rollers, my vacuum suddenly started acting like it just got promoted.
Why This Kit Delivers:
🧹 Everything You Need, Nothing You Don’t – 8 filters, 8 side brushes, and 2 rolling brushes. That’s a lot of life for your vacuum. Basically turns one tired robot into a whole year of squeaky-clean effort.
🔧 Perfect Fit for the C10 – All parts snapped right in without forcing, trimming, or muttering curses. Side brushes spin like new, and the roller glides instead of thudding.
🌬️ Major Suction Boost – A fresh filter and roller made a huge difference. Dust, crumbs, and suspicious mystery fuzz are no match now.
🧼 Easy to Swap – Took less than 10 minutes to do a full refresh. No YouTube tutorials required—just a little common sense and maybe a screwdriver.
Brushstroke of Caution:
❌ Side Brushes May Wear Faster – They work great but aren’t quite as thick as the originals. For regular cleaning? Totally fine. For warzone-level pet hair? You may cycle through them faster.
Final Sweep:
This kit brings your C10 back to life, keeps it performing like new, and saves you the drama of tracking down individual parts. If you love your robot vacuum but hate how it’s been slacking off lately—this kit is your fix.

Useless filters
Filters don't fit - they're way too small.

A definite keeper :)
Size: C20 renewed, Size: C20 renewed
I had a shark that gave out after 3 years. (It didn’t have a mop) I ordered a new one from a different company and the new one I bought was defective so when I saw this one half price renewed I figured it couldn’t hurt because this one was only 50 more than the other one. I’m so glad the other brand was defective. This thing is amazing . The app was easy to set up after I realized the quick start card they send has and old obsolete app. Once I searched and found the right app. It’s called eufy clean . All went as planned. There app has so many things to customize. I have a fluffy carpet in my bedroom and was able to set the suction Lower so it wouldn’t damage the carpet. You can customize what rooms it mops , vacuums or if u want both and how many time it will pass through each room 1 or 2 times . I didn’t want a vacuum with a bag but I’m ok with compromising that . The app also has a section to tell u when it’s time to change parts for maintenance. It mapped my small apt very quickly. Its base is larger but it tucks under the base . My shark had no mapping and just bumped randomly around. So always a tapping while it was cleaning. I find this to be much quieter the only time it’s loud is when it returns back to the base ti dump dirt and that is the sound of a regular vacuum running and it’s only for a minute or 2 at tops. I cant speak for battery life because it’s renewed but it cleaned my on bedroom apart in about 40 minutes with 60% battery left. It came in its original box like it was brand new. Only a few indentations on the top of the actual vacuum from what I saw. As for longevity we will see but as of now this renewed item is a definite keeper.

Mapping all areas first
Size: C20 renewed
Great vac
Quick delivery
Easy set up
Mop wasn’t responding and customer service was amazing to help troubleshoot and get the problem resolved.
A little frustrated at first because the chat wasn’t as helpful and I could not reach them by phone but the email techs replied immediately and promptly responses and help.
