Pinnacle Micro Rejuvenator

I have a question regarding:
Pinnacle Micro Rejuvenator Microfiber Detergent Concentrate


I just bought it but was wondering is it meant for washing machines topped up from the top side (High Efficiency) or the ones topped from front ?

for ones like this:

or the fully automated ones like this:
