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.

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
