Excellent fit and value - recommended buy
Size: 3+12+12+2+1 pack
I rarely write reviews, but I'm so impressed by the fit and quality of this set that I made an exception. I'd been running my eufy 11S without brushes, and have been cleaning and reusing the filters for a while now and finally decided to buy replacements. The kit came packed well with everything in order and no damage. I replaced all of the worn parts and installed the brushes and did a test run - everything worked great. I expected some fitment issues because I've seen that with other kits, but I had no issues. The fact that you get multiples of almost everything is icing on the cake.
Oh, and I wasn't paid or given anything in exchange for this review, as much as that's worth now, haha.
I can recommend getting this kit for your robot vacuum, if it's the right set for your model.

Good option for an aftermarket replacement solution.
Size: 3+12+12+2+1 pack
I've been very happy with this product. I think it is a good price point for what is included. Everything was a directly compatible and everything fit as you would expect. The filter quality is good and since there are plenty in the kit I find I change the filters more often which is probably a good thing. I recommed.

Eufy Brushes wear out with daily use
Size: 4 Pack
These brushes help the Eufy continue to run efficiently. I have 2 dogs and run 2 Eufies daily. It is surprising how much sand, dust, gravel and hair gets vacuumed. My furniture isn't as dusty and my floor doesn't need mopping as often.
