Cimex vs 175 Rotary Machine

[Gero43]

Thanks to everyone for their help. I finally bought the Cimex, tried it in my house (low pile carpet) and in a residential rental (high pile carpet). Pictures attached.


First 3 pictures are: Before, after Cimex and after HW with rotovac on the same area. Satisfied with the results.
Last 2 are my house: After Cimex and HW with Rotovac (looks pretty good) and the other one is 2 days later (it looks weird), I'm not sure if it is because of the kind of carpet that make it look weird.


Sorry about picture quality, it is not the best at night.















So far I have two questions:
I also did the entrance of a building and the carpet looked spotless, smelled great right after Cimex, but next day when I came back it looked same colour as before and some salt stains reappeared. (I was using release it 2 not the hydro one so I'm not so worried about salt stains) but the colour looked bad like it was never done almost.

Second thing is, when doing Cimex and then HWE, should I wait for the Releaseit to fully dry before HWE? and is it better to do HWE first and then Cimex a day after or it doesn't really matter?
