Dry Fusion is my "cash cow". It earns me really good money on commercial low profiles.
I also use it as a problem solver eg. see the recently posted pictures of a BW in an Indian Restaurant. Also use it when access is a problem on residentials. But it wouldn't be my first choice for any woven or tufted cut pile residential or contract installation. Rinse extraction, whether T/M or porty, rules on this one.
Think of a rotary LM system as a way of expanding your business into the commercial low profile sector (a massive marketplace) and keep it as your problem solver, along with your Envirodri, for everything else.
Safe and happy cleaning
