Simpson Commercial Equipment

SIMPSON commercial cold-water gas pressure washers are built for facilities that pressure-wash daily -- parking structures, loading docks, fleet yards, and food-processing exteriors -- where a residential unit wears out in a season. Every SIMPSON model in this collection runs an AAA industrial triplex plunger pump, the same pump architecture used across professional-grade cold-water units, paired with a commercial-duty gas engine rather than a consumer small-engine.

The current SIMPSON lineup spans 3,700-4,400 PSI and 2.5-4.0 GPM. The entry unit, the PS60982-S Pro Series (3,700 PSI, 2.5 GPM), runs a Honda GX200 engine and is 50-state emissions compliant -- the only SIMPSON model in this collection cleared for sale in every US state, including California. Stepping up, the PS61350 Pro Series (4,400 PSI, 4.0 GPM) and the ALWB60825 Aluminum Water Blaster (4,400 PSI, 4.0 GPM, belt-drive) both run a CRX 420 engine with electric start, built for higher daily-duty-cycle use. Pricing across the 3 active models runs $749 to $1,799.99.

Choosing between them comes down to duty cycle and mobility. The PS60982-S suits facilities running a pressure washer a few hours a day and needing 50-state compliance for a fleet that crosses state lines. The PS61350 and ALWB60825 suit daily heavy-duty use -- loading dock degreasing, dumpster-pad cleaning, drive-through and parking-structure washdowns -- where the higher PSI/GPM cuts cleaning time and the electric-start CRX 420 engine holds up to repeated daily starts better than a pull-start small engine.

All 3 active SIMPSON pressure washers ship freight to US commercial facilities, with model-specific documentation included. For other pressure washer brands and PSI/GPM configurations, see Janitori's full pressure washers collection.
