When it comes to outdoor cleaning, Simpson pressure washers are widely recognized as some of the most reliable tools on the market. Whether you are a homeowner looking to clean your driveway or a professional contractor tackling a large-scale project, understanding the different models and accessories available is key to getting the job done efficiently. This guide provides a straightforward look at what makes these machines unique and how to select the best equipment for your specific needs.
Why Simpson Pressure Washers Are Popular
Simpson has built a reputation for combining high-quality engines with durable pumps. Most of their machines feature engines from trusted brands like Honda or Kohler, which are known for their longevity and ease of starting. This focus on premium components ensures that the machine remains functional even after years of heavy use.
Another reason for their popularity is the variety of the product line. From compact electric units to heavy-duty gas-powered machines, there is a solution for every type of cleaning task. By focusing on professional-grade materials, even their residential models often outperform standard consumer-grade equipment found in big-box stores.
Understanding Residential vs. Commercial Models
Before purchasing a pressure washer, it is important to distinguish between residential and commercial grades. The right choice depends on how often you plan to use the machine and the intensity of the cleaning tasks you face.
Residential Series (Clean Machine and MegaShot)
The Clean Machine and MegaShot series are designed specifically for homeowners. These models are lightweight, easy to maneuver, and perfect for cleaning decks, patios, and vehicles. They typically offer enough power to remove dirt and grime without the risk of damaging softer surfaces like wood siding.
Professional Series (PowerShot and Aluminum)
For those who need to use a pressure washer daily or for extended periods, the PowerShot and Aluminum series are better options. These models feature professional-grade engines and triplex pumps, which are designed to handle high-pressure output for hours at a time. The aluminum frames are particularly useful because they are corrosion-resistant and lighter than steel, making them easier to transport between job sites.
Key Specifications to Consider
When browsing for cleaning equipment, you will encounter two primary measurements: PSI and GPM. Understanding these will help you determine the cleaning speed and power of the machine.
- PSI (Pounds per Square Inch): This measures the pressure or “stripping power” of the water. Higher PSI is needed for tough tasks like removing paint or cleaning deeply stained concrete.
- GPM (Gallons per Minute): This measures the volume of water flowing through the machine. Higher GPM allows you to rinse away debris faster, significantly reducing the total time spent on a project.
- CU (Cleaning Units): To find the overall efficiency, multiply PSI by GPM. This number gives you a clearer picture of the machine’s total cleaning capability.
Essential Accessories for Better Results
The right accessories can transform a standard pressure washer into a versatile cleaning system. Using the correct attachment not only saves time but also ensures that you do not damage the surface you are cleaning.
Nozzle Tips
Most Simpson machines come with a set of color-coded nozzles. The 0-degree (red) tip provides a concentrated stream for tough spots, while the 40-degree (white) tip provides a wide spray for delicate surfaces like windows. Always start with a wider angle and move closer to the surface to avoid accidental damage.
Surface Cleaners
If you have a large driveway or sidewalk to clean, a surface cleaner is a must-have accessory. This attachment features a rotating bar with two nozzles housed inside a circular deck. It provides a streak-free clean and can finish a driveway up to four times faster than a standard wand.
Extension Wands and Hoses
For cleaning second-story siding or reaching high gutters, extension wands are incredibly helpful. Additionally, upgrading to a non-marring, kink-resistant hose can make the cleaning process much less frustrating by preventing tangles and protecting your driveway from black scuff marks.
Basic Maintenance and Safety Tips
To keep your pressure washer running smoothly, regular maintenance is required. Because these machines involve high-pressure water and internal combustion engines, safety should always be your first priority.
Engine and Pump Care
Check the oil levels before every use and change the oil according to the manufacturer’s schedule. For the pump, it is highly recommended to use a pump guard or lubricant, especially if the machine will sit idle for more than a month. This prevents internal seals from drying out and protects against mineral buildup from hard water.
Safe Operation Practices
Never point the spray wand at people or pets, as the high-pressure stream can cause serious injury. Always wear safety goggles to protect your eyes from flying debris. Additionally, if you are using a gas-powered model, never operate it indoors or in poorly ventilated areas due to the risk of carbon monoxide poisoning.
Winterizing Your Equipment
If you live in a climate where temperatures drop below freezing, you must winterize your pressure washer. Water left inside the pump can freeze and expand, which will crack the pump housing and ruin the machine. Drain all water from the hoses and use a pressurized pump antifreeze to ensure the internal components are protected throughout the winter months.
Finding the Right Solution
Choosing the right Simpson pressure washer involves balancing your specific cleaning needs with your budget. By focusing on the engine quality, the pump type, and the necessary accessories, you can invest in a tool that will provide reliable service for years to come. Always remember to read the manual for your specific model to ensure you are following the correct startup and shutdown procedures.
