Chemical advice for tiny portable

I'm just looking for a little advice on the home maintenance cleaning using a Kent C4 portable. I understand a proper cleaning should be done by professionals with a truck-mounted set up, but I do a lot of maintenance carpet washing due to having 4 kids and two dogs. The carpet throughout my house is the cheapest contractor grade available in 2009 when it was built.

My machine is a former Home Depot rental that I picked up for a hundred bucks from Facebook marketplace. It's similar to a Rug Doctor, but the brush spins instead of that weird back and forth vibration. It is missing the upholstery attachment and the pump was jammed. I am fairly handy, so I was able to tear it down, clean out the insides and put it back together with the pump working. It has a 3 1/2 gallon capacity and it seems like it's lifting the same amount back out of the carpet every time I run it.

Based on the advice in this video, I experimented with some Procyon powder:
I feel like it did a really good job, but it's a little expensive if you're only buying small amounts for home use. I also experimented with zep brand regular carpet shampoo from a hardware store. It did okay oh, but I was concerned that I'm leaving some residue in the carpet no matter how many water passes I make.

Does anybody have a good suggestion of what sort of chemical would give me the best bang for buck for general home cleaning?

I've seen some advice on this forum recommending just a pre spray on heavily soiled areas and then just running water through the machine, so I'd like to hear everybody's thoughts on that too if you are willing to share.

Thank you in advance for your time.

Get some Black Label as a prespray, Unchained for urine and Ultimate Fiber rinse for inside your machine. Thank me after.
