When diving into the world of pressure washing, understanding the types of pressure washers available is crucial. Let’s break down the two primary categories: gas-powered and electric. Each has its advantages and disadvantages, depending on your specific needs and preferences.

There are two main types of pressure washers: gas-powered and electric.

Gas-Powered Pressure Washers


  • Powerful Performance: Gas pressure washers typically offer higher PSI (pounds per square inch) and GPM (gallons per minute) ratings, which means they can handle tougher stains and bigger jobs more efficiently.
  • Mobility: Without the need for a power outlet, gas pressure washers offer greater portability and are ideal for outdoor use, especially in areas without easy access to electricity.
  • Versatility: They are more suitable for heavy-duty tasks, such as stripping paint, cleaning large decks, and washing siding.


  • Noise: Gas engines are significantly louder than electric motors, which can be a consideration in noise-sensitive areas.
  • Maintenance: They require regular maintenance, including oil changes, air filter replacements, and proper winter storage procedures.
  • Emissions: Gas pressure washers emit fumes, making them unsuitable for indoor use and less environmentally friendly.

Electric Pressure Washers


  • Quiet Operation: Electric models are much quieter than their gas counterparts, making them more suitable for use in residential areas and at times when noise would be disruptive.
  • Ease of Maintenance: With fewer moving parts and no need for fuel, electric pressure washers are easier to maintain and start with the push of a button.
  • Eco-Friendly: They don’t produce emissions, which is better for the environment and allows for indoor use in well-ventilated areas.


  • Less Power: Generally, electric pressure washers have lower PSI and GPM ratings, which may not be as effective for heavy-duty cleaning tasks.
  • Corded Limitation: Being tethered to an electrical outlet limits mobility and may require the use of extension cords to reach certain areas.
  • Durability: They may not be as robust as gas models, with some electric pressure washers being constructed from less durable materials to keep costs down.

Choosing between a gas-powered and an electric pressure washer comes down to assessing your specific needs, the types of jobs you’ll be tackling, and your personal preferences regarding maintenance, noise, and environmental impact.

Choosing the Right Size Pressure Washer

Choosing the right size pressure washer is essential for ensuring that you have enough power for your cleaning tasks without overdoing it. The size of the pressure washer’s engine or motor directly correlates to its total power, which is measured in two key metrics: PSI (pounds per square inch) and GPM (gallons per minute). Together, these determine the unit’s cleaning power or CP (cleaning units), calculated by multiplying PSI by GPM. Here’s how to understand the importance of size and power in pressure washers:

Here are the different categories:

  • Light-Duty Pressure Washers:
  • Produce water pressure levels under 2000 PSI.
  • Suitable for small decks, patios, or the occasional outdoor household item.
  • Medium-Duty Pressure Washers:
  • Produce water pressure levels between 2000 and 2800 PSI.
  • Suitable for the home’s siding, driveway, or fencing.
  • Heavy-Duty Pressure Washers:
  • Reach pressure levels between 2900 and 3300 PSI.
  • Suited for cleaning large areas of concrete or reaching a second story.
  • Professional Pressure Washers:
  • Produce water pressure levels of 3300 PSI and higher.
  • Designed for big jobs that take hours to complete, such as preparing a home’s exterior for repainting.

Small Pressure Washers:

  • Typically electric, with PSI ratings from 1,300 to 1,800.
  • Ideal for light-duty tasks such as washing cars, outdoor furniture, or small patios.
  • They are more manageable, easier to store, and usually sufficient for most residential needs.

Medium Pressure Washers:

  • Can be either electric or gas-powered, with PSI ratings from 2,000 to 3,000.
  • Suited for moderate tasks like cleaning decks, fences, and exterior siding.
  • They strike a balance between power and manageability, making them versatile for homeowners.

Large Pressure Washers:

  • Usually gas-powered, with PSI ratings above 3,000.
  • Designed for heavy-duty, large-scale tasks such as preparing surfaces for painting, cleaning large driveways, or commercial cleaning jobs.
  • They are more robust and powerful but also heavier and require more maintenance.

When selecting the right size pressure washer, consider the following:

  • Type of Jobs: Evaluate what you’ll be cleaning. Delicate surfaces require less power, while tough stains and large areas might need a more powerful unit.
  • Frequency of Use: If you’re using it frequently for various tasks, investing in a medium-sized washer might provide the best versatility.
  • Portability: Consider how important it is to move the pressure washer around. Smaller units are easier to transport and store.
  • Power Source Availability: Ensure you have the right type of power source. Electric washers need a power outlet, while gas-powered washers need fuel and can be used in more remote locations.

Selecting the Right Nozzle

The nozzle chosen determines the angle of the water stream. Pressure washer nozzles are universally color-coded:

  • Red Nozzle: 0-degree angle. Creates a powerful, potentially damaging water stream.
  • Yellow Nozzle: 15-degree angle. Suitable for pressure washing concrete around the house.
  • Green Nozzle: 25-degree spray. Used for all-purpose household pressure washing, like washing a car or cleaning patio furniture.
  • White Nozzle: 40-degree spray. Suitable for windows and siding.
  • Black Nozzle: 65-degree spray. Produces a gentle, light spray more suitable for wetting a surface, not cleaning it.

Pressure Washing Safety

To ensure safety while pressure washing, follow these guidelines:

  • Wear eye and hearing protection to protect yourself from debris and water spray.
  • Use both hands to securely hold the pressure washer and prevent it from flying out of your grip.
  • Maintain a safe distance of approximately 18 inches between the spray tip and the surface being cleaned to minimize the risk of damage.

Power Washing Different Surfaces

Here are some tips for pressure washing different surfaces:


  • Use a green-tipped nozzle for a 25-degree spray and a gas-powered pressure washer.
  • Move the pressure washer’s wand in an even up-and-down motion.
  • Use overlapping strokes to avoid visible lines.
  • Allow the wood to dry for at least a day, then seal it.


  • Use a high-GPM pressure washer and a yellow-tipped nozzle.
  • Sweep and brush off the surface before starting.
  • Use a concrete cleaning solution on any stains.
  • After pressure washing, let the concrete dry before applying a sealer.


  • Use a green- or white-tipped nozzle and a gas-powered pressure washer.
  • Fix any loose pieces of siding, cracks, or other breaches that could admit water during the cleaning process.
  • Apply soap to the siding with a soaping nozzle, scrub any particularly dirty areas, then rinse the siding with the green- or white-tipped nozzle.

Things to Avoid Pressure Washing

As you embark on your pressure washing journey, it’s essential to recognize that not all surfaces or items are suitable for high-pressure cleaning. Here are some things you should avoid pressure washing to prevent damage and ensure safety:

  1. Lead Paint Surfaces: If your home was built before 1978, it might have lead-based paint, which can be hazardous if disturbed. Pressure washing can create lead paint chips and dust, posing serious health risks.
  2. Asphalt Shingles: The force of a pressure washer can dislodge the granules from asphalt shingles, compromising the roof’s integrity and leading to water damage.
  3. Vehicles: While it might be tempting to use a pressure washer to clean your car or bike, the high pressure can force water into seals and crevices, potentially causing corrosion or electrical damage.
  4. Aged Wood: Old, softwood can be easily damaged by a pressure washer. The intense pressure can gouge wood, strip away paint, and erode soft grain, leading to an uneven surface.
  5. Windows: Glass can shatter under the high pressure, and water can seep into the seals, promoting mold growth or damaging the frame.
  6. Air Conditioners: Pressure washing an AC unit can bend or crush the delicate fins and push dirt deeper into the device, impairing its function.
  7. Electrical Panels and Meters: Water and electricity are a dangerous combination. Pressure washing electrical components can lead to short circuits and pose a risk of electrocution.
  8. Living Things: Never pressure wash pets, plants, or people. The force is too strong and can cause injury or damage.
  9. Gutters: While gutters can be cleaned with a pressure washer, doing it incorrectly can damage the gutters or your home’s siding.
  10. Outdoor Lighting: The high pressure can break light fixtures and force water into the electrical components.

For beginners, it’s crucial to start with a low-pressure setting and test a small, inconspicuous area before proceeding. Always wear protective gear, including goggles and gloves, and ensure you’re familiar with the equipment’s operation. If you’re unsure about pressure washing a particular item or surface, consult with a professional to avoid costly mistakes.

Remember, the goal is not only to clean but to do so without causing harm to your property or the environment. By avoiding these common pressure washing pitfalls, you can ensure a safe and effective cleaning experience.

Tips for Pressure Washing Around Your Home


When it comes to keeping your home’s exterior clean, pressure washing can be a game-changer. However, it’s not as simple as blasting water at your siding and hoping for the best. Here are 10 tips to help you pressure wash around your home effectively and safely:

  1. Choose the Right Tool: As mentioned, pressure washers come in both gas and electric models. Consider the size and type of jobs you’ll be doing to determine which is best for you.
  2. Be Safe: Always wear protective gear, including goggles, gloves, and ear protection if using a gas model. Ensure you’re on a stable surface and be aware of your surroundings.
  3. Prep Properly: Before you start, remove any obstacles, cover nearby plants or furniture with a tarp, and close all windows and doors to prevent water from getting inside.
  4. Protect Your Plants: Water at high pressure can damage your plants. Wet them with a garden hose first to create a water barrier, and be cautious with the pressure washer around them.
  5. Patch Any Broken Surfaces: Before pressure washing, repair any cracks or chips in the surfaces you’ll be cleaning. This prevents water from seeping in and causing more damage.
  6. Start From a Distance and Take Your Time: Begin washing from a few feet away and move closer as needed. Rushing the job can result in uneven cleaning or damage to the surface.
  7. Know Your Nozzles: Different nozzles have different spray patterns and pressures. Use the right nozzle for the job to avoid damaging surfaces.
  8. Adjust the Spray Angle: The angle of the spray can affect cleaning effectiveness and safety. A wider angle has lower pressure and is better for delicate surfaces.
  9. Use Detergents Wisely: Some jobs may require cleaning solutions. Use detergents designed for pressure washers and for the specific surface you’re cleaning.
  10. Rinse Thoroughly: After cleaning, rinse the surface with plain water to remove any detergent residue. This is especially important for surfaces that may come into contact with pets or children.

By following these tips, you can ensure that your pressure washing not only leaves your home looking great but also preserves the integrity of your property and keeps everyone safe.
