Owen, when you say "brands", are you referring to the machine itself?

Depends how you want to apply.
If using a pressure washer, low pressure can be achieved by down streaming. Which is basically the use of larger size nozzles that reduce your pressure. With the right chemicals, the use of low pressure can clean alot of things.
Heres a chart to help.

Owen, They don't really make a "low" pressure pwer... Like Johnson said you can achieve this with nozzles... Like one of my machines is a 5.5@3500 I use a downstreamer to apply soap then instead of using the the "correct" nozzle which is a #5.5 to rinse I use a #15 this drops my pressure down, to around 1200psi @ 5.5gpm which some will say this is still to much pressure but I stay back and just mist the surface.. this allows me to still clean the block or brick on the foundation.. around here the is a LOT of clay stains on houses.. by using the #15 nozzle this allows me to clean the clay with out changing my nozzle.... plus if you use to big of a nozzle w/ a ds it will keep sucking chem and you will have to have a rinse tank (fresh water) to put your ds hose in.. Thats another reason I use #15 nozzle...

Thanks for the advice, Johnson and Daniel
I have a ps that is 5gpm at 3000, with down stream set up.
I don't understand the last part ,

A #15 only produces about 500psi with that machine not 1200psi. What most guys don't understand is that the 'inline' pressure isn't the actual pressure felt by the substrate from a shooting stream of water. a person can stand 3 feet in front of a so called 'high pressure' #15 tip and not feel so much pressure as what comes out of a garden hose.
