Buying Guide

PSI and GPM: The Power Duo

Pressure (PSI) and flow (GPM) determine how effectively a washer cleans. Higher PSI blasts away tough grime, while higher GPM rinses faster. For most residential tasks, 3000–3500 PSI with 2.5–3.0 GPM is sufficient. Commercial jobs often require 4000 PSI and 4.0 GPM or more. Models like the SIMPSON Cleaning PS3228 PowerShot 3300 PSI Gas strike a good balance for homeowners, while the Gas Power Washer For Professionals. CAT Triplex delivers high output for demanding use.

Pump Type: Triplex vs. Axial

The pump is the heart of a pressure washer. Triplex pumps (AAA or CAT) are more durable and suitable for frequent use, while axial pumps are lighter and more affordable. For longevity, choose a triplex pump. The Gas Power Washer For Professionals. AAA Triplex and the Simpson Aluminum Series models use commercial-grade triplex pumps that last for years. If you need a lighter unit for occasional use, an axial pump like the one in the Maintenance-free axial pump, Steel-tube frame can save money.

Engine Size and Type

Honda engines come in several displacements: GX200 (196cc), GX270 (270cc), and GX390 (389cc). Larger engines provide more power for higher PSI and GPM, but they also add weight and cost. For most homeowners, a GX200 is plenty. Professionals often prefer the GX270 or GX390 for continuous operation. The MechMaxx 4000 PSI 4 GPM Honda 389CC 11.7HP E-Start uses the largest Honda engine for extreme cleaning tasks. If you want electric start for convenience, look for models with that feature.

Build Quality and Hose Length

A sturdy frame protects the engine and pump during transport and storage. Steel frames are preferred for commercial use; aluminum frames offer a lighter but still robust option. Hose length affects your reach: a 25-foot hose works for small areas, while 50-foot hoses let you move around large driveways without repositioning the machine. The Simpson Cleaning PS60869 PowerShot 4000 PSI Gas comes with a 50-foot Monster Hose for maximum flexibility.
