In this blog, we’ll help you determine the perfect size pressure washer for your 2 story house.
Understanding Pressure Washer Sizes
When it comes to cleaning your home’s exterior, a pressure washer can be a game-changer. These powerful tools make quick work of removing dirt, grime, and other debris from your home’s siding, driveway, and other surfaces. Choosing the right pressure washer size can be a bit confusing, especially if you’re not familiar with the terminology.
Pressure washers come in a range of sizes, with different pressure and flow rates. Understanding these terms and what they mean can help you choose the right pressure washer for your needs. Here is a closer look at pressure washer sizes and what you need to know to choose the right one for cleaning your 2-story house.
PSI (Pounds per Square Inch)
PSI is the measure of the pressure output of a pressure washer. It determines the force at which water is sprayed out of the machine. For cleaning a two-story house, a pressure washer with a PSI of at least 2500 is recommended. This level of pressure is needed to effectively remove dirt, grime, and other stains from the exterior surfaces of a two-story house. However, the PSI isn’t the only factor to consider. The size of the nozzle, the flow rate, and the type of detergent used also play a significant role in determining the effectiveness of the pressure washer for cleaning a two-story house.
GPM (Gallons per Minute)
GPM, or gallons per minute, is an important factor to consider when choosing a pressure washer size for a two-story house. It refers to the amount of water that the pressure washer can output per minute, which affects the cleaning power of the machine.
For a two-story house, a pressure washer with a minimum GPM of 2.5 is recommended to effectively remove dirt and grime from higher areas. However, larger homes with more surface area to clean may require a higher GPM of 3.0 or more.
Note that GPM is just one aspect to consider when choosing a pressure washer size. The PSI, or pounds per square inch, also plays a role in determining the cleaning power of the machine. A balance between both GPM and PSI should be considered to ensure the pressure washer is powerful enough for the job.
CU (Cleaning Units)
CU, or Cleaning Units, is a measure of a pressure washer’s cleaning power. It is calculated by multiplying a pressure washer’s PSI (pounds per square inch) and GPM (gallons per minute) ratings. The higher the CU, the more cleaning power the pressure washer has.
When choosing a pressure washer for a two-story house, consider the size of the house, the amount of dirt and grime present, and the surface being cleaned. For a two-story house, a pressure washer with a CU of at least 3000 is recommended. This will provide enough cleaning power to effectively remove dirt and grime from the siding and other surfaces.
Note that using a pressure washer with too high of a CU can potentially damage delicate surfaces such as painted surfaces or window screens. Always start with the lowest pressure setting and gradually increase until the desired cleaning power is achieved.
Recommended Pressure Washer Size for a 2-Story House
If you own a two-story house, you know how difficult it can be to keep it looking clean and well-maintained. From dirt and grime buildup to mold and mildew growth, your home’s exterior can quickly become an eyesore if not properly cleaned.
A pressure washer can be an effective tool to remove dirt and stains from your home’s exterior, but selecting the right size can be challenging. Following are the recommended pressure washer size for a two-story house, so you can keep your home looking great all year round.
Light-Duty Pressure Washers (1,300 – 2,000 PSI)
Light-Duty Pressure Washers typically have a pressure output of 1,300 to 2,000 PSI. While these pressure washers may be suitable for smaller tasks such as washing cars or cleaning patios, they may not be powerful enough to effectively clean a two-story house. Therefore, it is recommended to use a pressure washer with higher PSI for this type of project.
Medium-Duty Pressure Washers (2,000 – 2,800 PSI)
Medium-duty pressure washers with a PSI range of 2,000 to 2,800, are recommended for cleaning a 2-story house. These pressure washers are powerful enough to remove dirt, grime, and stains from the exterior of the house, including the walls, windows, and roof. However, caution should be taken not to damage delicate surfaces or cause harm to oneself. It is recommended to choose a pressure washer with an adjustable pressure control feature to suit various cleaning needs.
Heavy-Duty Pressure Washers (2,800 – 3,300 PSI)
Heavy-duty pressure washers with a PSI range of 2,800 to 3,300, are also suitable for cleaning a 2-story house. These pressure washers have a higher PSI than medium-duty pressure washers and are capable of handling tough cleaning tasks, including removing stubborn stains, dirt, and grime from a variety of surfaces. They are ideal for cleaning large areas such as patios, decks, and sidings of a 2-story house.
If you are looking for a pressure washer that can handle heavy-duty cleaning tasks, a pressure washer with a PSI range of 2,800 to 3,300 is recommended.
Making the Right Choice
When choosing a pressure washer for a 2-story house, consider several factors. First, the size of the pressure washer is crucial. A pressure washer with a PSI of 3000 or higher and a GPM of at least 2.5 is recommended for cleaning a 2-story house.
You should consider the type of nozzle that comes with the pressure washer. A 25-degree nozzle is best for general cleaning, while a 15-degree nozzle is better for tough stains and dirt.
Always think about the type of surface you will be cleaning. A pressure washer with a higher PSI can damage certain surfaces, such as wood or delicate stucco. In these cases, a lower PSI pressure washer or a special nozzle designed for delicate surfaces should be used.
Pressure Washer Types
Understanding the different types of pressure washers available and their features can help you determine the right size pressure washer for your two-story house. Following are the various types of pressure washers and their applications to help you make an informed decision.
Electric Pressure Washers
Electric pressure washers are a popular option for cleaning a 2 story house. They are lightweight, easy to use, and require less maintenance compared to gas-powered pressure washers. Electric pressure washers come in a range of sizes, with PSI (pounds per square inch) and GPM (gallons per minute) being important factors to consider when choosing the right size for your 2 story house.
A smaller electric pressure washer with a PSI of 1500-2000 and a GPM of 1.2-1.5 is suitable for light-duty cleaning tasks such as washing cars, outdoor furniture, and small patios. For medium-duty cleaning tasks such as cleaning driveways, fences, and siding, a mid-sized electric pressure washer with a PSI of 2000-2800 and a GPM of 1.8-2.3 is recommended. For heavy-duty cleaning tasks such as removing stubborn dirt, grime, and stains from large surfaces like decks and sidewalks, a larger electric pressure washer with a PSI of 2800-4000 and a GPM of 2.4-3.5 is required.
Note that using a pressure washer with too high a PSI can damage surfaces and that the size of the pressure washer needed may also depend on factors such as water pressure and flow rate.
Gas Pressure Washers
Gas pressure washers are a type of pressure washer that is powered by gasoline. They are More powerful than electric pressure washers, making them suitable for heavy-duty tasks like cleaning large areas or removing tough stains. Gas pressure washers are also more portable and don’t require an electrical outlet, making them a good choice for outdoor cleaning tasks.
When choosing a gas pressure washer for a two-story house, consider the pressure output and the flow rate. Look for a model with a pressure output of at least 3000 PSI and a flow rate of at least 2.5 GPM. This will provide enough power to clean the exterior of a two-story house effectively.
Consider the weight and portability of the gas pressure washer. Look for a model with sturdy wheels and a comfortable handle, as this will make it easier to move around and use for extended periods.
Hot Water vs. Cold Water Pressure Washers
Hot water pressure washers are generally more effective at removing dirt, grease, and grime than cold water pressure washers. This is because hot water is better at breaking down and dissolving these substances. Hot water pressure washers are often used in commercial and industrial settings where heavy-duty cleaning is required.
Cold water pressure washers, on the other hand, are typically more affordable and easier to maintain than hot water pressure washers. They are a good choice for homeowners who need to clean their home’s exterior, driveway, or patio. Cold water pressure washers are also more portable and can be used in areas where a hot water source is not available.
When choosing between hot water and cold water pressure washers, consider the specific cleaning task at hand. If you need to clean a large, heavily soiled area, a hot water pressure washer may be the best choice. If you need to clean a smaller area or don’t have access to a hot water source, a cold water pressure washer may be sufficient. Ultimately, the decision will depend on your individual needs and budget.
Evaluating Your 2-Story House
Evaluating your 2-story house is the first step in determining the appropriate size of the pressure washer for your cleaning needs. Below are the key factors you need to consider when evaluating your home, so you can make an informed decision on the size of pressure washer that’s best for your 2-story house.
Assessing the size and layout of your home
When it comes to pressure washing a two-story house, it’s crucial to assess the size and layout of your home to determine the right pressure washer size. This assessment should include factors like the square footage of the house, the number of stories, and the layout of the property, including any challenging areas to clean.

By evaluating these factors, you can determine the appropriate pressure washer size and pressure settings for the job, ensuring that you achieve the desired level of cleanliness without causing damage to your home’s exterior.
Estimating the amount of cleaning tasks
Before deciding on what size pressure washer to use for your two-story house, estimate the amount of cleaning tasks that need to be done. This includes the size of the area that needs to be cleaned, the type of surfaces that need to be cleaned, and the level of dirt and grime buildup.
For example, if you have a large two-story house with a lot of outdoor surfaces such as driveways, patios, and decks, you will need a pressure washer with a higher PSI and GPM rating to get the job done effectively and efficiently. If you have stubborn stains or heavy dirt buildup, you may need to use a higher pressure setting or a specialized cleaning solution.
On the other hand, if you have a smaller two-story house with less outdoor surfaces to clean, a lower PSI and GPM rating may be sufficient. Consider the specific cleaning tasks you need to accomplish before selecting the appropriate pressure washer size.
Additional Pressure Washing Accessories
In addition to choosing the right size pressure washer for your 2 story house, there are also various pressure washing accessories that can help you achieve a thorough and efficient clean. These accessories can enhance the functionality and versatility of your pressure washer, making it easier to clean hard-to-reach areas, delicate surfaces, and tough stains.
Below are some of the most useful pressure washing accessories that you can use to get the most out of your pressure washer and make your cleaning tasks a breeze.
Extension wands are a valuable pressure washing accessory for cleaning hard-to-reach areas of a 2-story house. They allow you to extend the reach of your pressure washer wand, making it easier to clean high surfaces such as second-story windows, eaves, and gutters. When choosing an extension wand, make sure to select one that is compatible with your pressure washer and has a length that suits your needs. Using an extension wand can save time and effort, as well as reduce the risk of accidents and injuries from trying to clean elevated areas without proper equipment.
Surface cleaners are pressure washer accessories that help in cleaning large flat surfaces like driveways, patios, and decks efficiently. They are particularly useful for 2 story houses as they can cover large areas quickly, reducing the cleaning time significantly.
Surface cleaners come in different sizes, and choose the right size for the job. For a 2 story house, a surface cleaner with a diameter of 16 to 20 inches is recommended as it can clean a larger area and provide better coverage.
Consider the pressure rating of the surface cleaner. A surface cleaner that can handle a pressure of 3000 to 4000 PSI is suitable for cleaning a 2 story house effectively.
Using a surface cleaner with the right size and pressure rating can save you time and effort while cleaning your 2 story house. Make sure to read the manufacturer’s instructions carefully and follow safety precautions while using a surface cleaner.
Detergent injectors are an essential accessory for pressure washing a two-story house. They allow you to apply soap or other cleaning agents to the surface being cleaned, which can make the cleaning process more effective and efficient.
There are two types of detergent injectors: downstream and upstream. Downstream injectors are located after the pump and are the most common type. They are easy to use and allow for the use of a wide range of detergents. Upstream injectors are located before the pump and are more difficult to use, but they are more efficient and allow for a higher concentration of detergent to be used.
When using a detergent injector, follow the manufacturer’s instructions and use only the recommended detergents. Using the wrong detergent can damage the surface being cleaned or the pressure washer itself. Rinse the surface thoroughly after using a detergent to avoid leaving any residue behind.
When considering the right pressure washer size for a two-story house, it’s recommended to opt for a machine with a minimum PSI (pounds per square inch) of 2500 and a flow rate of at least 2.3 gallons per minute (GPM) for effective cleaning without causing damage to the surfaces.
When it comes to cleaning a two-story house, a pressure washer can be a game-changer. However, choosing the right size of pressure washer is crucial to ensure efficient and effective cleaning. In this blog, we have discussed the factors that determine the ideal pressure washer size for a two-story house, including water flow rate, pressure, and cleaning power.
