That reference was following a demo of the Cimex and the discussion with the rep', I believe the O/P method to be far superior and having used bonnets on extremely filthy retail establishments, I can assure you, they remove soiling and plenty of it.
There have been demos where O/P's have outperformed T/M's, the last time I mentioned this, a Mr D Bolton mentioned that " he was there "
Just as there are some detergents, micro splitters, etc, which are better than others, there are also encap' products that are better.
I have been experimenting ...................on light beige, at home and end of lets, allsorts, and been astonished at the results.
This has been over the past 6 months , or so and there is no increase in resoiling, over previous H/W/E. Incidentally.................the product I've been using and found to be better than the Cimex one, cost about £5 for 5 litres.
My reason for experimenting, has been due to the state of my body and my determination to keep working.
With spinal compression / sciatica / arthritis, it's hard going and I have been experimenting, to find a compromise, which " ideally " would be an O/P about 15 " which would be used with encap' they have them in the US.
There is a huge bonus, in terms of the tiny volume of water used in encap' cleaning and the low cost of power usage.
