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.

Lots of extras!
Size: 2+12+12+2 pack
The brushes are a bit flimsier than the original but otherwise fine. I needed it for the rectangular filters more than anything

EUFY 11S
Size: 2+8 pack
Used to replace the ones for my EUFY 11S vacuum. They fit just like the ones and got my vacuum back to cleaning really good. Didn’t realize how loud my vacuum had become until I replaced these parts.
