Types of Pressure Washers
When you are exploring the pressure washers on the market, you will find that they run on either electric or gas. An electric power washer is best for light duty, such as cleaning an outdoor grill, a personal vehicle or the floor of your garage. They typically run at 1,300 to 1,400 psi.
These are typically lighter, more portable and quieter than a gas-powered pressure washer. These must be connected to a power outlet that contains a ground fault circuit interrupter to prevent electrocution. A 12 to 14 gauge extension cord is necessary for safe use.
Gas-powered pressure washers are what you want for tougher and larger cleaning jobs. It delivers a higher stream of water pressure with a psi rating that can exceed 3,000.
You will use more water with this type of power washer, but it is more effective. This type is used for things like removing deep stains on wooden decks, preparing the siding on a house for painting or for deep-cleaning your concrete. When you rent a power washer, you are most likely to find a range of gas-powered options.
In most cases, you will find a gas power washer because these are more common and there are more of them on the market. They also tend to be more diverse and have a greater range of power to ensure that they can clean a number of different surfaces.
However, if you want a simpler unit for general home use, you should take the time to look at the electric power washers that are available. These tend to be simpler when it comes to both use and maintenance.
These are ideal for those who are not familiar with using this type of unit at home due to greater simplicity.
Pressure Washer Features to Consider
- High-pressure hose: These put out more cleaning power. They typically extend to approximately 25 feet, allowing you to easily move around while you clean.
- Nozzles and tips: Most consumer pressure washers have a single nozzle or tip that you can adjust. However, there are various options allowing you to use a nozzle or tip that is focused on the job at hand.
- Detergent tank: This is where you put approved cleaners and chemicals to use during pressure washer cleansing.
- Sturdy tires: You will need to move your pressure washer around, so you need tires that allow for easy movement and transport.
- Accessory storage: Many pressure washers have several accessories that you can remove and switch between.
- Water temperature: Some jobs require a certain temperature of water and you want to make sure that your chosen pressure washer can provide it.
- Telescoping handles: This allows you to adjust the length of the handle to ensure more efficient use.
- Quick-connect capability: This ensures that you are able to easily switch between various components so that you can get the job done as quickly as possible and without constant breaks.
There are also a number of accessories to learn more about. These work to make using a power washer easier. Certain accessories also help you with certain types of cleaning, such as scrubbing away tough stains or ensuring that your power washer is able to reach things like the second story of your home.
These accessories include:
- Brushes: Sometimes you need a brush to get some scrubbing power to ensure effective cleaning.
- Angled wand: This is helpful for jobs like gutters.
- Chemicals: These work for specific cleaning jobs.
- Extensions: These allow you to clean higher surfaces.
- Surface cleaners: These are ideal for sidewalks and driveways.
How do Pressure Washers Work?
Things get messy, but having a pressure washer on hand ensures that you are able to clean things that traditional soap and water cannot handle. A pressure washer is made up of an air compressor and a garden hose, when you are looking at the simplest of structural definitions.
The following provides a basic explanation of how this type of equipment works:
- There is a container or bottle that holds detergent or chemicals and these flow through the hose.
- Cold water flows through another hose and it is filtered. The water comes from a type of faucet, such as an outdoor garden hose faucet.
- A diesel engine or an electric motor works to power the power washer.
- A motor or an engine work to power a water pump. This component works to draw in both water and detergent or chemicals. It mixes both of these together. It also usually heats the water to approximately 125 to 155 degrees Fahrenheit. Since the unit will heat the water, you must only use cold water with a power washer.
- The combination of water and a detergent or a chemical come out of a high-pressure exit hose and any attached nozzle or tip. This helps to reduce water waste by up to 80 percent compared to a traditional water hose.
The insides of the power washer provide more insight to how this type of equipment works. Each has a specific function and must work properly or else you will notice problems with your pressure washer’s performance and overall operation.
The following internal components are in a pressure washer and they work in the following ways:
- There is an external housing that contains the components and helps to protect them from the outside environment.
- This type of equipment contains an electric motor.
- To prevent all water from getting into the unit’s motor, there is a type of insulating plastic foil that adds an extra layer of protection.
- The motor contains a central shaft that spins at a high speed. This is what ensures that the water pump is able to work efficiently.
- Another component is the reciprocating water pump. To make the water into a high-pressure jet, the pump has to reciprocate. Inside a pressure washer, you will find a number of pump units.
- The pump piston is a type of chamber that ensures that the water is able to get to a high pressure.
- The water pipe is the part of the unit where water is pumped out after it is sucked in from the faucet that you are using.
How to Use a Pressure Washer
For most homeowners, a pressure washer that runs on 1,300 to 3,000 psi is going to be the best option. This allows you to tackle pretty much any job you need to clean in and around your home.
You will want to refer to the unit’s owner’s manual to get the exact information necessary to safely and efficiently use your chosen power washer. In general, you will use the following steps:
- Properly assemble all of the pieces and parts of your pressure washer.
- Connect your unit to an approved water source.
- Insert any necessary cleaners or chemicals that you need for the job.
- Double check to ensure that everything is properly installed.
- Use the pressure washer, paying attention to the gauges to ensure it is operating efficiently.
There are a number of tips and bits of information that you should know to ensure a positive cleaning experience. Keep the following in mind when you are using your pressure washer for various cleaning projects:
- Before you start cleaning, wet the whole surface to prevent streaking.
- It is best to start further away from the surface and slowly move closer until you achieve your desired results. This prevents using too much pressure on any surface.
- To ensure an even and smooth cleaning experiencing, never get directly on the surface that you are trying to clean. If you keep a distance, this will improve the cleaning experience.
- It is best to put about five feet between the end of the nozzle and the surface that you are cleaning.
- Make sure to always move the nozzle steadily and do not use fast or erratic movements. A smooth and steady movement ensures that you get consistent results with cleaning.
- Never hold the nozzle in the same spot for more than two to three seconds. This results in the final cleaning results being uneven and inconsistent.
- Use a cleaning detergent when you are trying to clean a surface with heavy staining. The right detergent ensures that you are able to deeply penetrate the staining. These work at higher pressures. Never use a chemical at higher pressures because this can result in not enough of the chemical penetrating the stain because it will just splash off the surface. The detergent is more likely to stay in place and do its job.
- Use a narrow spray when you are trying to clean surfaces that are more difficult to reach. You can also extend the telescoping handle to ensure that you get enough power in the water spray on surfaces that are at a distance.
- Always work on small sections at a time. This ensures consistent cleaning throughout the entire project. For example, if you are cleaning a deck, only work on two boards at a time. Once you full clean these, move onto another set of two boards and clean these. You should do the same for all other surfaces.
- Make sure that you never walk away from your power washer during operation. The pressurized water that comes out of the gun component can cause serious injuries in the form of cuts or penetrating the skin.
- Make sure that you always protect your eyes and ears when you are using a pressure washer. It is especially important to wear the right eye protection when you are using a detergent or a chemical because there is always a chance that they can splash back into your eyes and cause irritation or more serious damage.
- Always make sure that you are using the correct nozzle. If you use the wrong nozzle, you can cause significant damage to the surface that you are cleaning.
- Make sure that you have solid footing and stable balance when you are using a pressure washer. Never stand on something that you could fall off of. The pressure of the water may cause you to fall backward.
- Never point the gun component at people, plants or animals. It can cause significant injuries or damage. Due to the power of the water, you also must never point it at things like screens and windows.
Pressure Washer Uses and Benefits
There are a number of uses and benefits associated with a pressure washer. When you have this type of equipment at home, you are able to get a lot more done to maintain various things around your home.
The following are common benefits that come with owning your own pressure washer:
- You save money by doing your own cleaning at home. You will not have to hire a specialist to do things like clean your deck and driveway.
- You will protect your investments. Keeping your home, yard and vehicles clean is an easy way to help ensure that they maintain their good condition for a long period of time.
- You are going to save water. While you are using water as part of the cleaning process, the fact that it is pressurized actually saves water.
Another benefit is that a single pressure washer can be used to clean a number of things. There are dozens of uses for power washers, depending on whether you are using them at home or in a commercial or an industrial setting.
However, most people want to learn more about the home uses since this type of equipment is becoming increasingly popular among homeowners. The following are what the majority of people use a consumer pressure washer for:
- To clean various types of fending around the home

Capabilities of a Pressure Washer
Knowing what you can clean with a pressure washer is critical in ensuring that you choose the best one. Know the information below so that you choose a pressure washer with the right range of capabilities:
- Light-duty pressure washer: These range from about 1,500 to 1,900 psi. This is best for cleaning things like sidewalks, patio furniture and stairs.
- Heavy-duty pressure washer: These range from about 2,900 to 3,200 psi. These are ideal for things like sidewalks, garage floors and driveways.
- Medium-duty pressure washer: These range from about 2,000 to 2,800 psi. These work for fences, patios, driveways, decks and garage floors.
- Extra-duty pressure washer: These are 3,300 psi and greater. These are best for the toughest jobs, such as industrial cleaning.
To choose the right pressure washer, consider when you need to use it for. If you are going to use it for various cleaning projects, make sure that you choose one with the right range of psi to do this.
In general, the tougher the job, the higher the psi you need to get with a pressure washer. If you get one with a good psi range, you will be able to tackle all of the necessary jobs.
Write down the things you need to use a pressure washer to clean and then look at the various psi necessary for each job to pick the right pressure washer.
Picking Out the Best Nozzle for a Pressure Washer
When you buy a pressure washer with under 2,400 psi, it generally comes with one nozzle that you can adjust for the cleaning job. This nozzle typically works with a fan pattern of zero to 60 degrees.
Some models have a standard nozzle that is either a turbo or a rotating so that the water stream is spun for more effective cleaning.
If you are using a heavier-duty piece of equipment, there are typically five nozzle tip options that are color-coded. The colors work in the following ways:
- Red nozzle tip: This is ideal for a water stream that is small and very concentrated. Removing debris and tough stains from metal and concrete often warrants this nozzle tip. Never use this in siding or wood or it could cause damage.
- Black nozzle tip: This is used when you need low pressure and are using detergent.
- Green nozzle tip: This is best to sweep away mud, leaves and dirt. It sprays at 25 degrees.
- Yellow nozzle tip: This works when you are preparing a surface. It sprays at 15 degrees to remove mildew, dirt or paint. You can use this nozzle tip on the majority of surfaces.
- White nozzle tip: This tip works at 40 degrees. It is best when you need to clean surfaces that are more delicate, such as home siding, stucco walls or glossy surfaces.
It is important to clean your nozzles regularly to keep your pressure washer working efficiently. If you do not maintain your pressure washer nozzles, you risk causing damage to your pressure washer.
Because of this, you must look at the nozzle before and after each use to ensure that it is fully clean and open. Use the following steps to ensure clean nozzles:
- Disconnect the gun and spray wand. Never clean a nozzle when these are connected.
- Use a small wire piece to clear the nozzle. A paperclip usually works well.
- Use water to flush backward into the nozzle.
- Reconnect the gun and the wand.
- Use the pressure washer for a minute or two to ensure that there is no partial or full clog remaining.
If the cleaning process fails, you should get a new nozzle since you cannot safely use a clogged nozzle on a pressure washer. You can buy the nozzles separately so that you only have to replace the ones that you need.
Making Sure to Choose the Proper PSI for the Job
You now have a good understanding of psi so it is time to put that knowledge to use so that you pick the right psi for what you need to clean. The following shows you the psi that you need to use to clean certain types of projects.
Use this as your guide to ensure that you buy a power washer that has the right PSI:
- If you are cleaning more delicate things, such as your personal vehicles, you want to use a psi of around 2,500
- If you are trying to clean wooden surfaces, such as your deck, you want to choose a psi of around 2,700
- If you are going to be cleaning types of masonry or concrete, you want a psi of around 3,000
- If you need a power washer for industrial applications or for something like removing graffiti, you want a psi of around 4,000
This, of course, does not cover every single application of a power washer. However, you can deduct from the information above approximately the amount of psi you will need for your cleaning projects.
It is important that you always have enough power without having too much. If you use too much power, you risk causing extensive damage to whatever object or surface you are trying to clean.
