Buyer guides

Straight answers to common buyer questions.

• Hot water or cold water: which pressure washer you need If what you clean is greasy or oily, you need heat; if it's loose dirt and mud, cold water with good flow costs less to buy and run.
• GPM vs PSI: what actually makes a pressure washer clean faster Pressure breaks dirt loose and flow carries it off; past about 3,000 PSI, more GPM is usually what speeds up commercial work.
• Choosing a pressure washer trailer rig Pick the machine for the work, the tank for the water you'll have on site, and a chassis your truck can pull full; here is the published grid to start from.
• California-compliant pressure washer rigs What the California-compliant Alkota 5357C diesel build is, what the tag covers and what it doesn't, and the questions to settle before you run a rig in California.
• Fleet washing equipment: what a fleet wash needs Hot water for road film and grease, enough flow for a line of trucks, water for the yard you wash in, and a plan for the runoff.
• Construction site pressure washing: equipment and water Flow for mud, heat for grease and hydraulic oil, the right chemical for concrete, and a tank big enough for a site with no water.
• Municipal pressure washing equipment One hot-water rig can serve several departments; graffiti needs its own truck, wash water needs a plan, and a bid file needs a written spec.
• Starting a mobile pressure washing business: the equipment side Pick the work first, then the machine; know the real cost of a rig, how financing and ordering work, and which local rules to check before your first job.
