For the 11S Max, the parts fit great. Changing out the parts is easy, and the parts are durable. I like that this kit has a new filter for everytime you change out the rotating brushes. Changing out the parts make the eufy vacuum cleaner function better everytime. I can’t tell a difference in the noise level when changing out the parts. Overall, thus is totally worth the money to keep the Eufy running in its best shape.

Perfect replacements for the G30

I wanted to replace the filters in my old G30 more frequently, as it's still running like a champ. I figured keeping up on it more often would help prolong its life expectancy. So far, so good. The less expensive replacement parts definitely help me not get upset every time I want to replace something. All parts from this pack fit perfectly, and the price is reasonable enough to avoid pushing replacements to the very last minute—at least it did for me, lol.
