How to clean Safavieh hand knotted carpet with Hoover carpet cleaner🤔

🧐🙄Hoover carpet cleaner/Washer

We just bought a Hoover carpet cleaner....I have used both cleaning solutions included in the package..no luck...the machine did clean the carpet a bit...but I can still see the dark..grey areas on that white carpet very easily....

Regularly used/ walked on carpet.... No small kids...no dogs or cats at home..

I have included the pictures of the Hoover machine, the cleaning solutions I used and the image of the carpet I try to make it white [cream white] again. 😪

Only 8 months old carpet..

If somebody knows how to remove the dark stained areas( walking areas) on such carpet....what solutions to use.... Please...HELP

Thanks
