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.

Fits my old eufy
Size: 3+12+12+2+1 pack
This set fits my older model eufy and has extra parts for newer models. The filters did not fit our model (our fault for not doing proper research) but the fan sweeper is awesome.
