I am glad that this worked for you, but I can say from experience that this is not the case in the section of Citrus Grove I am in, built in 2021.
The developer supplied 30 low flow oscillating heads. Opening them up full throttle did not fix the problem, fits because they allow so little water through, but also because what was on the screen was an amalgam of green slime and sand.
The developer contractor did not entirely think through the overlap situation on my lawn, so I tinkered around with replacing some oscillators with sprays. Again, opening them all the way up did not work, for the same reason. The sand reinforces the slime and it becomes a tenacious substance.
I have 2 out of 30 heads high capacity high flow sprays, maybe those would work as flushers, but installing them is very tricky to balance with the other heads, they would have to be at the bottom of the loop, and could only at best help unclog the zone they are installed on ( I have four zones ).
So I am not a paid shill, just saying, that irrigation filter is worth every penny.

Your situation is not unique. Most homes have those rotator sprinkler heads installed. These heads will need to be replaced when that grit gets into it's mechanism. There is no way to fix that problem once it happens. You can install the large spray heads as some have but you need to make sure you have adequate flow for the rest of the rotator heads in that zone. But note, having a couple of these high volume heads will not "flush" out all that slime and debris from getting to those rotators. All that slime and junk you describe will be filtered by the Irrigation filter.
I can tell you when I first moved in, after one round of cleaning all the 30+ filters only to have them get clogged a month later when the ponds got low, I called Chuck and we installed a filter on my system. 3 1/2 years later, still working perfectly and never had to clean any sprinkler head filters or replace any heads. I feel bad when I see some of my neighbors paying a lot to have the Irrigation guy come and fix their sprinkler heads. I can always tell when the ponds are low by the presesence of these Irrigation trucks running around my village.
