Counter rotating brush. Can they cause a run

[Gordy]

Have started using a crb for agitation prior to extraction.

Has anyone has any problems with the creating a run with loop pile carpet?

only if there is a loose string that you would catch....same as using a vacuum though and CRB might be more forgiving than a vacuum

That is always possible when using any powered brush on looped carpet. Pay attention to what you are doing to minimize the risk.

The longer brushes on a crb reduce the risk.

Shorter stiffer brushes on a vacuum increase the risk.

If you see loose yarn, cut it off and/or glue it back down. If that is not an option, just avoid the spot. A CRB will not pull out a yarn that is bound to the backing but it could further pull one that is already loose. Not common, but it could happen.

If I see them I hit them with my lighter and push it down back into the spot. It will never run or come loose after that.
