Hi Jonny
And welcome to our UK Carpet Cleaning Community.
I too am a great fan of Micro Splitting technology. It's not the easiest type of product to appreciate and use successfully if you follow your usual routine when HWE cleaning with detergents, but once mastered, it's usually the first solution of choice, certainly on most residential work. The big plus for me is that they are exceptionally safe products to use. No hazard/poison etc. signs on the labels. They are actually food grade products and are edible if you're mad enough :

When I was using detergents, I was a great fan of Prochem. Like Chemspec, but to a lesser degree IMO, the range appeared to be complicated by many products which seemed to do the same job, so I found a select, smaller list from the range that worked for me, and stuck with those. For a short while before I changed to Micro Splitting, I used Spitfire Advanced, a multi-fibre, Woolsafe Approved, freshwater rinse pre-spray from an Australian ccompany called Research Products. If I were to return to detergents, this would be my preferred product. The results were stunning. Used at 1:30 and without any rinse detergent too!
I have recently received from another company brand within this group called Citrus Resources another freshwater rinse pre-spray called Citrafresh. It's designed for very heavy/greasy soiling and is also a fresh water rinse product.
The other company within this Australian group is called Dry Fusion. The Dry Fusion System is a unique rotary pad system which excels on low profile carpets, but has been used to stunning effect on all types of installations. As you quite rightly said, there is a general resistance to rotary pad cleaning because of the fibre distortion issue. However, if I were to say that Brintons, a world leader in quality woven wool carpets, has given the Dry Fusion System the thumbs up, would that be enough to satisfy most of the doubters?
Like you Jonny, there are many of us here in the UK who are equally passionate about our industry, and I look forward to sharing our views, experiences and opinions.
Safe and happy cleaning

Ken
