I'm not a fan of my cross shaft at all, but I still need a replacement because I'm not going to throw away $250 just like that. The exchange helped with the poor performance.
Pros
EASY TO CLEAN AND REPLACE - Snaps into place for quick and easy daily tool-free replacement. Clean under running water and allow to dry completely before reuse. For the best performance of your vacuum cleaner, it is recommended to replace the filter every 3-6 months.
