I only talk from 22 years experience and using about 20 machines, possibly more. I have no connection to anyone in the cleaning industry.
There is no point in me giving an opinion on what I think is the best machine, as you can only compare against a budget, or intended use.
If I was starting up, rather than backing out, I would regard the Prowler, as the machine that appears to tick most of the boxes...............for me !
