In this case, it is necessary to replace the complete rotor unit. Regular cleaning of the rotor chamber with a small brush also makes sense, since a lot of dirt settles there, which prevents the filter performance.

Thing is absolutely garbage. Ball didn’t make it back once! Broke in half
Junk and they don’t follow through with the shipping that they claim. Said between 7am and 11am. Don’t post it if ya can’t fulfill your shipping expectations

Good toy for dogs
This is a great toy! I do wish the handle was a little longer because I do not have a lot of upper body strength due to health issues. I can still throw with this further than I can without the launcher so my dogs really love it and get excited any time I get this out!
