You didn't really make clear what, specifically, you 'disagree' with. First, cleaning performance data matters, not suction, airflow etc. alone. I suggest you look at more than one poor internet source to learn more. Secondly, the sources you cited wonderfully evidence of a lack of understanding of even basic science, that again, is out there for you to look at. There was even a thread on this very forum recently that went through the science and exposed the shocking ignorance too frequently displayed, such as the remedial errors of using vane anemometers to measure airflow in non-uniform flows, and failure to appreciate why this doesn't matter for carpet cleaning anyway. It's all out there for you if you really care...
