This morning i tried out the Pureforce/oxyforce at my house i put it in my mytee big boss battery sprayer gave it only a few minutes of dwell then just gave it a little agitation using a grandi groomer, the one with the brush at the end, then rinsed and extracted with hot tap water only in my mytee ltd5.
my carpets are a light cream color and are not very dirty at all as i clean them regularly, so i wasn't expecting to see much of a difference. But to my surprise there was a definite noticeable difference.
So, so far so good although not a good test due to my carpets not being bad at all ( just normal soiling)
The real test will come when i use it on something really dirty. I normally will agitate with either my CRB or 175 so results will be better then just agitation with grandi brush.
I'll keep you all updated
