SIMPSON Trailer-Mounted 4200 PSI Gas Washer
This trailer-mounted system combines mobility with commercial performance. It uses a Honda GX390 commercial-grade engine for reliable, easy starts and a CAT Industrial triplex plunger pump rated at 4200 PSI and 4.0 GPM. The design suits contract cleaners, mobile detailers, municipalities, and resorts requiring rapid deployment. The 150-gallon water tank reduces refills on large jobs, while the 100-foot hose extends reach across sites. DOT certification confirms suitability for on-road use as a self-contained pressure washer system. Included accessories emphasize professional-grade operation.
Key features include a quick-start Honda engine, a sturdy 31-inch steel lance, a professional spray gun with a safety lock, and a 3/8-inch by 100-foot high-pressure hose built for kink resistance. A full set of five quick-connect nozzle tips (0°, 15°, 25°, 40°, Soap) supports a wide range of cleaning tasks, from degreasing to delicate surface washing. The system is designed for straightforward job-site setup: pull up, connect the spray gun, start the engine, and begin cleaning.

Practical upgrades like an enlarged hand crank for rapid retraction, a 90-degree outlet elbow to reduce kinks, and a locking mechanism for fixed lengths enhance user efficiency. It mounts on walls, trailers, vans, or other flat surfaces, enabling flexible workflow in diverse job sites.
Compatibility spans air and liquids with reinforced brackets for secure mounting. The reel is designed to stay organized and accessible, making it a common addition to trailer setups where hoses require reliable retraction and extension during large-scale cleaning projects.

Buying Guide: Trailer Mount Pressure Washer Considerations
- Power and performance: Compare PSI, GPM, and engine type. Trailer systems often balance high PSI with dependable engines for continuous use on large projects. Look for commercial-grade pumps and sturdy fuel options.
- Water supply and capacity: A larger onboard tank reduces refills on extended jobs but increases trailer weight. Ensure compatibility with your vehicle’s towing capacity and braking system.
- Mobility and mounting: Confirm mounting options for trailers, vans, or flatbed trucks. Consider skid plates, vibration dampening, and corrosion-resistant materials for outdoor use.
- Hose and accessory management: Long hoses and multiple nozzle tips demand reliable reels and quick-connects. Brass swivels and reinforced hoses extend service life and reduce downtime.
- Durability and maintenance: Heavy-duty steel or aluminum frames with protective finishes resist rust and wear. Check availability of replacement parts, such as pumps, hoses, and reels, for long-term maintenance.
- Safety and regulatory: DOT-certified or road-legal units help with on-road transport. Review safety features like gun locks, chemical compatibility, and emergency shutoffs.
- Transport and storage: Assess overall weight, ease of loading/unloading, and storage space on your trailer or vehicle. Factor in fuel, water, and accessory storage ergonomics.
- Cost of ownership: While not a price guide, consider maintenance costs, accessory upgrades, and warranty coverage when evaluating total cost of ownership over time.
Trailer-mounted pressure washers deliver a balance of mobility and power for commercial cleaning. Selecting the right combination of engine, pump, hose reels, and mounting accessories ensures efficient operation on jobs that require rapid setup and large-scale cleaning. When evaluating options, consider how each component integrates with your fleet, typical job sites, and maintenance practices to maximize uptime and return on investment.
