Most successful pressure washing businesses start with the same core rig: a commercial 4 GPM / 4,000 PSI machine with a Honda engine and a real triplex pump (CAT, General, or Comet), a 20-inch surface cleaner, 100 feet of kink-resistant hose on a reel, a nozzle set, and a downstream chemical injector. That setup handles driveways, sidewalks, patios, and house washes - the jobs that build a customer base. This collection has that core equipment plus the upgrade path: skid packages with water tanks, telescoping wands, gutter cleaners, and sewer jetter kits for adding services as you grow.
