Just done a lounge and dining room wool carpet.
PSG, dwell, agitate then extracted with Ninja using steamate facility on it.
It was in a good state and owner had vacced prior to my arrival so I thought,
I'll extract using steam but just plain water in tank.
Came up a treat.
Will try this approach again with wool, even to the extent of using Powerburst
as pre spray.
Just a thought, sometimes it's nice to experiment.
