Honestly I think it was just that there were better more efficient ways to filter a tank. Including canister filters, and improvements to hang on back.
Reverse undergravel filtration setup

Interesting concept but there will probably be a very good reason why it's not popular in the hobby.
Goldfish are messy so if the OP is looking to keep his substrate clean without vacuuming, then this would work, to a degree, though the modern way of using powerheads to stir gunk up and getting rid if it that way is wayyyy better imo.
Your substrate would have to be pea sized at least and only a thin even layer all over the tank to ensure an optimum even flow upwards of water. Any undulation in your gravel layer and the flow of water would simply come up through the thinnest, ie, easiest route. Leaving the thicker layers of substrate to become clogged, which makes the whole concept pointless.
You wouldn't have plants with goldfish, usually, so no problem there. But how would this method work with plants? Your substrate would, if the method was working efficiently, be spotless and totally devoid of nutrient for roots.
And at the end of it all, you still need a good filter in your tank to take away the waste that is pushed upwards out of your gravel and into the water column.
I'm struggling to see any real benefit of this method. But keep us updated S Soni on how you get on with it.
Oh, and welcome to the forum.

I would like to create extra good bacteria and push food off the substrate. Do i conect the output of my powerhead to the inlet of an internal filter? I do have an external canister as well? Or should I connect the powerhead to my existing external canister?
I don't have plants so no problem with it. I am just finding it difficult to decide should i connect the powerhead to a new internal filter or let my external filter do the work after powerhead pushes the dirt from substrate
Your canister will pick up the debris if you attach a power head to the undergravel filter. The power head should keep the particals suspended while the canister sucks them up. Having your canister output on the opposite side of the tank from the input should enhance this.
The problem I see having detritus sucked up in a canister, is the canister is not usually user friendly to clean out, meaning all that detritus is still in the tank spewing back nutrients as it passes thru.
If it was sucked into a HOB, and cleaned out every 2 or 3 days, then you're accomplishing something.
So if having it et sucked into the canister your option, if it were me, I'd just do more water changes and vacuuming as opposed to the reverse flow thing.

Agree.
If this is how you want to do it, it will require more canister maintenance. I don't see a reason for this so called booster.
