The closest thing to a need I have for a pressure washer is to determine whether I would like going into pressure washing for a job - which would probably necessitate learning landscaping too at some point, as I am unsure how common pressure washing services are sought after as a standalone thing. I have done a little research in that direction, but not much, since I would need some sustained use to determine whether I would want to really commit to something like that. My thought there was to volunteer services using it for neighborhood/community cleanup, which could build a portfolio if I wanted one, and make the places around me nicer, perhaps. As for knowledge and tools for maintenance, probably not, but I would be able to learn/get what I need in either realm.
