Most of the used pressure washers at Ritchie Bros. are built for contractor and fleet work, not the driveway - think hot water units, trailer-mounted systems, and skid-mounted gas units from brands like Hotsy, Alkota, Easy-Kleen, and EMC.
Hot water or cold water pressure washer - which do I need?
Hot water units cut grease, oil, and baked-on grime far faster, making them the standard for fleet washing, engine degreasing, and food-service equipment. Cold water units cost less to run and handle general dirt, mud, and exterior surface cleaning just fine.
Portable, skid-mounted, or trailer-mounted - what's the difference?
A portable or cart unit moves easily between jobs but carries limited fuel and water. A skid unit mounts permanently in a truck bed or at a fixed wash station. A trailer-mounted unit - like the gooseneck-mounted systems in our current inventory - tows a self-contained wash station from site to site, which is common for mobile fleet washing and jobsite cleaning operations.
What PSI and GPM do I need for commercial cleaning?
Most commercial-grade units run 3,000 to 4,000 PSI at 4 to 8 GPM, enough for degreasing equipment, stripping paint, and prepping concrete. Match flow rate (GPM) to the job as much as pressure - a higher GPM clears grime faster even at the same PSI.
What should I check before bidding on a used pressure washer?
Check engine or motor hours against the asking price, run the pump to confirm steady pressure with no leaks at the fittings, and inspect hoses and the wand for cracking or wear. On a hot water unit, check the burner coil for scale buildup and confirm the burner lights reliably. On a trailer-mounted unit, check tire condition and the axle and hitch for wear.
