Simpson Cleaning 3600 PSI Gas (ALH3425)
The Simpson ALH3425 combines professional performance with a portable design suited for contractor use. It features a Honda GX200 commercial engine and a AAA industrial triplex plunger pump delivering up to 3600 PSI at 2.5 GPM, with thermal relief to prevent overheating. The aircraft-grade aluminum platform and 10-inch pneumatic tires support stability and maneuverability on varied sites, while a 50-foot high-pressure hose minimizes re-cueing during large projects. The unit is well-suited for deck cleaning, wood restoration, and other demanding tasks common in contracting work.
Key advantages include durable construction and reliable cold-water performance, enabling steady operation through long days of job-site cleaning. Users should consider fuel logistics and maintenance needs for gas-powered units, especially on remote sites. This model is compatible with a range of Simpson accessories, expanding its versatility for different cleaning challenges.
Simpson Cleaning 3400 PSI Gas (ALH3228-S)
The ALH3228-S is a practical choice for contractors needing strong cleaning power with reliable start-up. It delivers 3400 PSI at 2.5 GPM, powered by a Honda GX200 engine, and uses a rugged aluminum frame that resists corrosion while remaining light enough for easy transport. Its compact footprint makes it suitable for job sites with limited space, yet it retains enough mass to stay stable during high-pressure use. The 50-foot hose and multiple nozzle tips facilitate efficient work on decks, fencing, and exterior surfaces.
Operators gain from a straightforward setup and a robust pump system designed to withstand frequent use. For teams cleaning multiple properties, this model offers a balance between performance and portability. Maintenance considerations include keeping the engine well-tuned and checking nozzle wear over time to sustain peak cleaning results.
Simpson Cleaning 4400 PSI Gas (WB60824)
This model targets heavy-duty commercial use with 4400 PSI at 4.0 GPM, driven by a CRX engine. It delivers high-output performance ideal for large surface areas, concrete cleaning, and stubborn buildup. The setup includes a 50-foot steel-braided hose for durability, a 48-inch insulated wand, and a versatile spray gun with a five-tip nozzle kit (0°, 15°, 25°, 40°, and Soap). The triplex pump design provides reliable flow and heat management essential for extended cleaning sessions.
Pros include powerful cleaning capacity and professional-grade components, while considerations focus on fuel handling and transport due to heavier weight. This unit is best suited for fleets or contractors who regularly tackle demanding commercial jobs and require maximum throughput and durability.
2025 Upgraded 100bar 2.3GPM Electric (Tecoloy)
The Tecoloy model emphasizes energy efficiency and quiet operation with a PM motor and 100-bar (≈1450 psi) capability at 2.3 GPM. It uses a horizontal triplex pump and a compact design, making it suitable for smaller job sites or maintenance tasks around facilities. Key features include a low-noise profile (65 dB) and a durable pump designed for extended service hours. While electric units may have lower maximum PSI compared to gas models, they offer reliability, lower operational costs, and easier maintenance for continuous cleaning cycles on commercial properties.
This model is best placed for facilities maintenance, parking garages, and periodic deep-cleaning tasks where emissions, noise, and maintenance simplicity are critical considerations. Users should evaluate electrical supply needs (outlets and extension cords) and ensure the power source is stable enough to support consistent performance.
Westinghouse WPX3200e Electric
The WPX3200e stands out with a 3200 max PSI and 1.76 GPM, powered by a durable induction motor. It features an onboard soap tank and a 25-foot hose, with a five-nozzle set, including a soap option for detergents. The high-performance motor and maintenance-friendly axial cam pump deliver reliable cleaning power with lower noise and emissions adherence suitable for commercial properties, sidewalks, and exterior walls. Its compact footprint and lightweight design enhance portability between worksites and service vehicles.
Considerations include limited PSI compared to gas models; ideal use includes lighter to medium-duty cleaning tasks, storefronts, and maintenance jobs where speed and efficiency are valued without fuel handling and exhaust concerns.
Westinghouse WPX3000e Electric
The WPX3000e offers a balanced electric option with 3000 max PSI and 1.76 GPM, coupled with a rugged induction motor for consistent power. A built-in soap tank and interconnected nozzle set provide practical cleaning versatility for cars, fences, driveways, and patio furniture. The 25-foot hose length and lightweight frame support straightforward transport across multiple sites, while the vacuum-friendly design reduces energy draw and noise relative to gas-powered units. This model suits maintenance crews and small contracting teams aiming for reliable electric performance.
Buying Guide: Key Purchase Considerations
Power needs: Gas-powered units typically deliver higher PSI and GPM ranges, making them ideal for heavy-duty commercial tasks and large exterior cleaning. Electric models are quieter, cleaner, and lower-maintenance, suitable for lighter commercial work or areas with noise restrictions.
Portability and durability: Look for solid frames, robust hoses, and durable pumps (triplex or axial cam) that can endure frequent transport and long job hours. Pneumatic tires and rollable frames help with mobility on uneven surfaces.
Maintenance and parts availability: Consider engines or pumps with widespread service networks and readily available replacement parts. A reputable warranty and customer support can significantly affect long-term costs and downtime.
Accessory ecosystem: A broad nozzle kit, spray wands, surface cleaners, and foam cannons expand versatility. Ensure compatibility with common standard fittings and accessories (such as M22).
Operational needs: Evaluate the typical cleaning tasks ( decks, sidewalks, vehicles, walls ), surface material sensitivity, and required detergent use. For large fleets, consider models with onboard chemical tanks to minimize refilling interruptions.
Noise and emissions: Electric options reduce noise and emissions, making them preferable for urban settings, shared facilities, and daytime cleaning windows. Gas models may require ventilation and fuel logistics planning.
Total cost of ownership: Beyond the purchase price, factor in fuel or electricity, maintenance intervals, pump longevity, and potential downtime. A slightly higher upfront investment in a durable, service-friendly model often saves money over time.
