Manual brush vs rotary attachment on a tricky flue job

I spent 45 minutes fighting with a manual brush on a clay liner yesterday before swapping to a rotary attachment on my drill and finished in 10 minutes flat. Has anyone else found certain flue shapes just don't work with manual tools?

Man, that rotary attachment is a GAME CHANGER on certain liners. I had a job a few years back with this old clay liner that had some weird offset at the top from a previous repair. Manual brush just kept snagging and bouncing around, I was cussing up a STORM. Swapped to a rotary and it chewed through that weird spot like butter. But here's the thing - I've also had rotaries just completely fail on really soft or crumbling clay, where the manual brush's gentle scraping actually did LESS damage. It really depends on the age of the liner and how brittle the material is. Some of those old hand-made clay tiles with rough joints are a total nightmare no matter what you use.

@markl75 Even air movers can wreck crumbling tiles faster than either brush.
