Here's a bargain for domestic works. See through how the machine is now.
Get rid of the stupid water tank on the top. Get it serviced. Machine for life.

I've still got a 170 bar, 15LPM Hilta Yanmar in the unit, as a back up back up. Had it 8 years.
With the H & M waiting for a new head set and fuel line issues with the latest machine I needed it last week.
Bar or LPM = Both.
When you jump up to 15LPM, 21 LPM, 30 LPM @ 200 bar etc the speed of cleaning increases massively but you have to feed that and without a good water supply the machine is pointless.
Same machine with 300 - 500 bar pump will have a lower flow rate so use less water but the water it is using will hit the surface harder.
I have an ICM Contractor, from Lee Kenny, 200 bar @ 40LPM, I can get a Speck pump up to about 1000 bar to fit the machine and use less water. (down to about 12 -15 LPM
Will it clean any quicker - I'll let you know when I get the H & M back and I buy the pump.
I don't know whether anyone has done any real life testing of two machines set up, one on flow and the second on pressure.
I've always been of the thinking that more flow is better.
I sell my service in getting in, getting done and getting out of the way, with as little disruption as possible. I tell the client it will be disruptive but that will be minimised by the short amount of time it will take.
