If you ever try a 'real' one it will blow your socks off. 200 bar @ 20

And to add meaning, 20 lpm is what a garden hose on 4-5bar supply with no
nozzle might give you. Rather more than the carwash one...


Sorry for the late reply. That's interesting to know. A lot of (non
uk-diy) people seem to think that pressure washers make your water
meter spin into orbit, but what you are saying is that they take the
same flow of water but increase the pressure, just as their name would
suggest. So they do not use any more water than someone using a hose
on their car/patio/whatever. I should have, but never did, realise
that before. Thanks.
