Flex King HD Cleaning

[DeepSpringFarm]

Hello,
I put in a Flex King HD 6' liner on my Progress Hybrid. I wanted to do my first cleaning on it before we start it up this fall.
I called Chimney Liner Depot and they recommended selling a poly brush kit.
I was wondering about the Sooteater.
Roof is steep, but I can get up to the top without much difficulty.
What would be the simplest,most effective cleaning system for a DIY. Obviously, I don't want to damage the liner.
Thanks!

Either a brush or a rotary cleaner will work fine. Honestly with a heavy wall liner you will have a hard time hurting it. We have even used rotary chains on a few without hurting them.

I have the same liner knock on wood no damage from the sooteater in the past two years.
