    I’ve been looking at PWs online. Price variance seems to be several hundred dollars. How does one decide? What other specs do I need to be considering?

    Also, are there advantages/disadvantages to buying from a big box store like HD or Lowes, Amazon, other online stores? What about extended warranty plans?

    Thanks for your advice.

    Psi is mostly a marketing gimmick. GPM is what gets the work done.

    It depends on what you want to do with it. I personally have a 4gpm and 4000 psi commercial unit. Honda 390 and cat pump. I can clean a two story house standing. Also use a 20" commercial surface cleaner with it for drive ways and walks. Works good, no customer issues at all. Very strong unit

    For now I want to do hard surfaces — sidewalks, driveways, porches, mailboxes. I might do house washes eventually, but not for now.

    Do you ever find that the gpm at a homeowners hose bib is not aqueduct to keep up with the gpm required for the pump?
