This was a training session we were doing in a nursing home, we were using their own extraction machine a Karcher puzzi 100, not the most ideal extraction machine for the size of their home, there was so much urine and heavy soils we had to use the upholstery tool to pull them out, they were delighted with the results and were going to invest in a commercial extraction machine as they use their own staff for doing all cleaning. (we dont sell cleaning equipment, just provide solutions and training)
