I have a 2019 Honda Jazz. The windscreen washers have become very week, with water barely reaching the glass. Pump seems to buzz as it should, so removed jets and cleaned, soaked overnight in descaler but no difference. Water from the hose near the bonnet squirts about 6-10 feet. Is this powerful enough to show there is not a pump problem, but the jets still partially clogged? I have seen websites saying to check pump flow or pressure but they don't say how.
Very weak windscreen washers.

You may have a clogged filter.
For an easy first step, put a hosepipe down the filler neck to the bottom of the bottle, and let it vigorously wash out any sludge or dirt.
You could also have a blocked, pinched or leaking hose. When the jets are off, does water squirt out of the open hose ends?
You can buy new jets, though your car might have non-standard fittings.

The jets, are the smallest part of the system, and so much more inclined to debris blocking them. A bit of fuse wire, will clear the jets without damaging them, or if you have access - an airline, blowing through from the jet outlet.
Surely the jets will only be a few quid each, not worth faffing about trying to unclear them.
Soak again over night using a lot of vinegar
Much quicker to fix, than to source, and fit. Do you replace your tyres, rather than simply inflate them when they need a bit of air?
You’d be surprised. Some jets can be £20 or more, especially if they are heated.
I just clear with a pin or needle , descaler doesn’t easily penetrate such a small opening .
