To ensure the longevity and optimal performance of your MT11 Brush Extender Pro:

7.2 Pole Connection Feels Loose
- Verify that the extension pole has a standard 3/4" threaded end.
- Ensure the extender is fully screwed onto the pole.
- If using a quick-connect pole, ensure it is properly engaged with the extender's fitting.
