Hi Mike
I would suggest you look at the Kirby Brush Roll part number 152505, which at a glance looks the same as the 152502 (the brush roll you have in your G6), but with a critical difference: the 152505 has stiffer bristles!
Notice that the 152505 (left) has bristles which are more tightly packed together (stiffer) than the 152502 (right), whose bristles are more flared out at the ends (softer). The 152502 has bristles which are the same softness as the original brushroll for the G6. In fact, you will notice it is close to the original G6 brush roll, except the rows are staggered by 90° halfway down each chevron. The 152505 has the firmer bristles, and is the original brush roll that was used from the Ultimate G through the current Avalir. Another way you can tell the difference between the two brush rolls is that the rows of bristles change direction half-way down the brush roll of the 152502, pointing towards the center of the nozzle much like those on the original chevron style G6 brush roll. On the other hand, the rows of bristles on the 152505 all angle the same direction: away from the LED indicator magnet.
When I got my G6 2000, I made the mistake of replacing the original brushroll with the 152502. I just felt it wasn't agitating any better like I was expecting. Then I discovered I bought it when I intended to buy the 152505.
Let me tell you, it made a huge difference for me. Finally, with the 152505, my Kirby was agitating like I wanted, vibrating the carpet much more vigorously and now making the famous carpet "buzz" that the Sentria and other newer Kirbys make. I now use this brush in my G5, G6 2000, and G6 2001 and am much more pleased with these cleaners now.
Good Luck!
PS I enjoy your YouTube videos. Keep up the good work!
