My extreme 22 is over 3 years old now. I always use supreme brushes which are classed as heavier, It’s got some spinning sections but I just clamp it an inch from the top.
Love it.
I’ve realised that key to keeping them going is to not get grit inside the pole. Every time I move around to the rear or front of the property I coil up the pole hose with a cloth in my hand to clean it at the same time.
This way, I’m never dragging the hose through dirt, then extending that up inside the pole.
Extremes all the way, they are the best pole out there in my opinion.
