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.
