The Ultimate Buying Guide: Choosing the Right Simpson Pressure Washer
Simpson pressure washers are famous for their power and reliability. Whether you are a homeowner or a professional, these machines help you clean tough surfaces quickly. Choosing the right model can feel tricky. This guide will help you pick the best one for your needs.
1. Key Features to Look For
When you shop for a Simpson pressure washer, pay attention to these three features:
- PSI and GPM: PSI measures water pressure, while GPM measures water flow. Higher numbers mean faster cleaning.
- Engine Type: Most Simpson models use reliable Honda or Simpson-branded engines. Honda engines are known for long life and easy starting.
- Pump Quality: The pump is the heart of the machine. Look for axial pumps for lighter jobs and triplex pumps for heavy-duty, long-term use.
2. Important Materials
The build quality determines how long your machine lasts. Simpson uses high-quality materials to resist wear and tear:
- Steel Frames: Most frames feature powder-coated steel. This prevents rust and protects the engine from bumps.
- Brass Fittings: High-end models use brass connectors. Brass does not crack or leak as easily as plastic.
- Steel-Braided Hoses: These hoses resist kinking and bursting. They handle high pressure much better than rubber hoses.
3. Factors that Improve or Reduce Quality
Several things change how well your pressure washer performs:
What improves quality:
- Proper Maintenance: Changing the oil and cleaning the air filter keeps the engine running smoothly.
- Triplex Plunger Pumps: These pumps last much longer than cheaper axial pumps.
- Pneumatic Tires: Large tires make it easy to move the unit over grass and gravel.
What reduces quality:
- Leaving Water in the Pump: Freezing water can crack your pump during winter. Always use a pump saver fluid.
- Low-Quality Fuel: Old gas can clog your carburetor. Use fresh fuel to keep the engine healthy.
4. User Experience and Use Cases
Simpson pressure washers serve many needs. For light cleaning, like washing a car or a small deck, a 2,800 PSI model works perfectly. For heavy-duty jobs, such as cleaning oil stains off a driveway or stripping paint, you should choose a 3,400 PSI model or higher. Most users find these machines easy to assemble. They provide a professional clean that saves you hours of manual scrubbing.
Frequently Asked Questions
Q: Are Simpson pressure washers good for beginners?
A: Yes. Many models are user-friendly. Just follow the manual for the first start-up steps.
Q: Do I need to buy extra nozzles?
A: Most Simpson units come with a kit of quick-connect nozzles. These cover almost every common cleaning task.
Q: Can I use hot water in my Simpson pressure washer?
A: Most standard models are cold-water units. Check your manual before using hot water to avoid damaging the pump seals.
Q: How often should I change the oil?
A: You should change the oil after the first 5 hours of use. After that, check it every 50 hours.
Q: Is it hard to find replacement parts?
A: No. Because Simpson is a popular brand, parts like hoses, nozzles, and spray guns are easy to find online or at hardware stores.
Q: Can I use soap with these machines?
A: Yes. Most models include a detergent injection system. Always use soap designed specifically for pressure washers.
Q: How do I store the unit for winter?
A: Drain all water from the pump and hoses. Add a pump protector fluid to prevent internal corrosion.
Q: Are Simpson engines loud?

Q: What is the benefit of a triplex pump?
