I did a commercial recently low profile tiles which were very dirty it was a large area so decided it would be perfect for rotary method, i tried two different chemicals to see which was best M power and Prochem Pure Clean.
The results were ok ! in the areas where chairs had been the soiling was heavier, i was not able to remove all the soiling no matter how much i tried, and was very dissapointed that when i ran a white cloth across the area it came up filthy not just once but everytime

i repeated the rotary even using it dry in the end but made no difference

I started with a thorough vacuum, presprayed, agitated with Gen 4 then used the rotary, like other i have seen amazing visual results but i did not find that the muck that came out of the bucket was anywhere near what would have came out with HWE, if a customer had seen the cloth after wiping the floor "after" cleaning he would probably have not paid the bill
