Buying Guide

Pressure and Flow Rate

PSI (pounds per square inch) measures cleaning power, while GPM (gallons per minute) indicates water volume. For heavy-duty tasks like stripping paint or cleaning concrete, aim for at least 3000 PSI and 2.0 GPM. The DeWalt 3300 PSI gas pressure washer delivers 3300 PSI at 2.4 GPM, making it ideal for residential and light commercial use. The Simpson PowerShot 4400 PSI model offers even more punch for professional jobs.

Engine and Pump Quality

The engine and pump determine reliability and longevity. Honda and CRX engines are known for easy starts and durability. The Simpson PS3228 uses a premium Honda GX200 engine, while the DeWalt 3300 PSI model features a DeWalt 208cc engine. Look for maintenance-free pumps with thermal relief valves to prevent overheating. For more on portable options, see our guide on top cordless pressure washers for home use.

Hose Reach and Mobility

A longer hose reduces the need to move the machine frequently. Most models include a 25-foot hose, but the Simpson PowerShot 4400 PSI comes with a 50-foot hose for greater reach. Pneumatic tires on a welded steel frame make transport easy over rough terrain. The DeWalt 3300 PSI model has 10-inch pneumatic tires for smooth maneuvering.

Included Accessories

Quick-connect nozzles (0°, 15°, 25°, 40°, and soap) let you adjust spray patterns for different tasks. Some models include a turbo nozzle for extra cleaning power. The Westinghouse WPX3400e electric model comes with a half-gallon soap tank and five nozzles. For gift ideas, check out our best pressure washer gifts for homeowners.

Regular maintenance includes checking the oil level, cleaning the air filter, and draining the fuel if storing for long periods. The DeWalt 3300 PSI model has a low-oil shutdown for engine protection. Always follow the manufacturer’s guidelines for seasonal storage.

Can I use a gas pressure washer for car washing?

Yes, but use a wide-angle nozzle (40° or soap) to avoid damaging the paint. The DeWalt 3300 PSI pressure washer includes a soap nozzle and is safe for car cleaning when used correctly. Always test on a small area first.

What is the difference between axial cam and triplex pumps?

Axial cam pumps are common in residential models and are maintenance-free, while triplex plunger pumps are more durable and used in professional models. The Simpson PowerShot 4400 PSI uses a triplex pump for longer life, while the DeWalt 3300 PSI uses an axial cam pump for reliable residential use.
