I've been doing the whole landscaping/snow removal/total property management gig for some time now. I've been looking to add pressure washing to my list of services. I know experience is important and I have a several years behind the gun. My ex-boss used to have a sweet pressure washer with a Subaru engine and it worked great. So my question is: What brands should I look into? What psi/gpm should I look for in a strong unit. I'm looking for a machine that can take hours of use which can clean pressure treated wood and trex decks, pool patios, outdoor furnature, walk ways and driveways. I know the best equipment costs money and I'm ok with that. Thank you in advance!
