The SIMPSON mobile trailer pressure washer is designed for professionals who need powerful cleaning performance, convenient starting and an onboard water supply for demanding jobs. Delivering 4200 PSI at 4.0 GPM, it combines high pressure and strong water flow to help remove stubborn dirt, mud and grime from durable outdoor surfaces. It is well suited for contract cleaning, mobile detailing, municipal maintenance, equipment washing and large property-care applications. The HONDA GX390 engine features recoil and key-start capability for flexible starting options at the jobsite. The CAT pump delivers reliable high-pressure water flow for consistent cleaning performance during frequent professional use. A 150 gallon water tank lets users bring a substantial water supply to locations where a convenient water connection may not be available. The over-the-road trailer configuration makes it easier to transport the complete cleaning system between jobsites and work areas. A 100 ft. steel-braided Monster high-pressure hose provides extended reach around equipment, vehicles and large cleaning areas. Five quick-connect nozzle tips provide spray options for concentrated cleaning, general washing, rinsing and detergent application. Premium 6-ply tires help the trailer travel across rugged terrain when moving between work locations. The single-axle steel trailer provides a durable platform for carrying the pressure washer, water tank and cleaning components together. This mobile system is a practical choice for contractors, municipalities, property managers and other professionals who need high-pressure cleaning capability ready to travel to the job.

Great machine for the price

8 years ago
I'm happy with my purchase; however, the machine appears capable of downstreaming because the suction nipple is downstream of the pump which would allow the use of bleach and not damage the pump. I have called Simpson and also posted the downstreaming question online a cannot get a definitive answer.

Yes, I recommend this product.
