Releasit. What one for residential carpets

[cookiemonster]

I am now thinking of trying releasit but notice there are a few different types. Can someone explain the difference between them and what ones are best for particular situations in residential situations.

I would ideally like an encap that breaks down dirt but also removes browning stains from carpet as this is common in many of the jobs I have. I would like one with an oxygenator as it helps make the carpet shine a bit more after cleaning.

Kind regards
James
