Pressure Washer Buying Guide

Here is the most important information that you need to know and consider when you are shopping for a new pressure washer.

Top 4 Considerations When Buying a Pressure Washer

These are some of the important questions to ask yourself before you start looking for a new pressure washer:

  1. What is the main task I will be using my pressure washer for?

    If you are mainly going to be using your new pressure washer to clean your car. Then 2000 PSI is plenty for those tasks. If you will be doing some heavy-duty pressure washing tasks like cleaning pavement or decks, you will want more PSI. Pressure washers with 2800 PSI or above are best for those types of heavily soiled jobs.

  2. Will I be using it at home only or at several locations?

    This will help determine how portable you will need your new pressure washer to be. If you are just using it around your home, then portability is not a big concern. This is just the opposite if you are taking your pressure washer to many locations. It will need to be highly portable and easy to store while transporting it.

  3. What type of ground is present where I will be using my pressure washer?

    Not all pressure washers are meant to go over rough terrain. So if you are going to roll your pressure washer across a lawn and rough dock boards to clean your boat, then it better have oversized wheels. Casters and regular size wheels go great across smooth pavement and floors but not much else.

  4. Will there be a power outlet nearby?

    This is something to definitely consider when purchasing a new pressure washer. Electric models are great for home use and other situations where you know you will have a power outlet nearby. That is not the case at all if you will be working at construction sites with no power yet or remote locations. Then it’s best to choose a gas-powered pressure washer.

14 Important Pressure Washer Features and Specifications

In order to make a sound pressure washer purchase, you need to be aware of these key specs and features of them:

  1. PSI

    This is perhaps the most important characteristic of any pressure washer for cars. That’s because PSI measures the amount of force that a pressure water model pushes out of the unit’s spray wand. The higher the PSI the more pressure a particular model pressure washer has. Cars have a pretty delicate finish so they do not need a high PSI to clean them. Other jobs, such as cleaning decks, fences, siding, and pavement require much more PSI. That’s why anyone who is purchasing a new pressure washer must be familiar with this number on any pressure washer that they are thinking about buying.
    It must also be noted that the listed PSI is a max PSI that a pressure washer can generate. You may also want to see if a manufacturer lists a working PSI too. It’s guaranteed that a pressure washer’s working PSI will always be lower than its stated max PSI.

  2. GPM Waterflow

    Here is a close cousin of PSI. GPM (gallons per minute) is another way to measure the output of any pressure washer model. Usually the more PSI a particular pressure washer has the higher its potential water output. A manufacturer will usually clearly list the number of gallons of water flow that a pressure washer can produce. Once again this is a max water flow measurement and such things as water hose size and nozzle selection can lower this figure.

  3. Power Source

    The type of power source that any pressure washer model has is a big deal in the selection process. That’s because it makes a difference as far as what a pressure washer can be used for. It also impacts such things as weight and portability. The two main ways that pressure washers get powered are by gas or electric. Gas pressure washers tend to generate more pressure and that makes them more versatile than electric power washers in most instances. Electric pressure washer technology has been catching up recently and they are usually lighter and more portable. More specifics on gas versus electric pressure washers will be discussed later in this article.

  4. Auto Pump Shutoff

    The technology in pressure washers has come a long way over the years. One of the most significant advances that have been made with them is the introduction of auto pump shutoff switches. These switches actually stop the pressure washer motor from running when the trigger on the spray wand is not being pushed. This has greatly helped to extend motor life which at one time was a big problem area with pressure washers. It’s a feature that you definitely want on any pressure washer that you buy.

  5. Type of Spray Wand/Extensions Included

    Pressure washers come with all different types of spray wands included in the package. The ones that people prefer the most are trigger activated like the models that you see at a carwash. These are nice because there are different settings on them including a continuous run setting that will reduce hand fatigue. Some spray wands have no ability to turn the water stream on and off and are made to do specific functions. This includes turbo power washing and soap dispensing wands. Included wand extensions are also great for window washing and getting to hard to reach areas.

  6. Included Water Hose Length/Quality

    It stands to reason the more water hose you have the less pressure washing repositioning that needs to be done. So be sure to know what size water hose comes with any pressure washer you are thinking about buying. You also want to make sure the included water hose is at least 20’ in length. Any shorter and you will probably get frustrated moving the pressure washer too much and purchase a longer one. You also want to consider how well an included water hose is made. Good water hoses are made of thick flexible rubber or ribbed plastic tubing that is also very flexible.

  7. Included Power Cord Length/GFI Protection

    The bigger the vehicle you will wash with your pressure washer the longer you want the power cord to be. That’s because with a short power cord you may have to move your pressure washer many times while operating it. That can be very inconvenient, to say the least. So know what size power cord any unit you are thinking about buying has.
    It’s also no secret that water and electricity don’t mix. Because of that, if you are using an electric powered pressure washer, you either want to plug it into a GFI protected outlet or have a model with a GFI protected cord. A GFI switch cuts off power to a pressure washer even if a minuscule drop in current loss is detected. Current loss can happen for many reasons in an electric circuit, some of which can cause a shock hazard. GFI circuit protection helps pressure washer operators avoid potential deadly shock hazards.

  8. Number of Included nozzles

    Most pressure washers come with a variety of interchangeable spray wand nozzles but the number varies between products. The more nozzles you have a wider variety of jobs that you can do with your new pressure washer. Spray nozzles are designed to do such things as angle the water spray and cut down or increase water pressure. You also want interchangeable nozzles that connect quickly as opposed to ones that screw on and off.

  9. Size/Weight

    Here are two things to strongly consider if you are going to be taking your new pressure washer to different locations. You don’t want to move around a heavy pressure washer from place to place unless you do many tough washing jobs with it. Larger size pressure washers tend to be heavy but they also tend to be hard to stow and transport. So choose wisely if you are looking for a pressure washer to use in many locations. Get the lightest and most compact model that still has enough power to do the jobs you need it to.

  10. Wheel Size

    This is another factor as far as portability is concerned. There are some pressure washer models that are only made to be rolled across flat, hard surfaces. This includes models with small size wheels and casters. It’s easier to go across uneven ground and other rough terrain if you have larger size wheels on a pressure washer. So consider where you will be using your pressure washer the most and what size wheels will make it easy to get there.

  11. Retractable Handle/Folding Handle

    Here is another item that can help make your new pressure washer easy to take places with you. This is especially true if you will be hauling your pressure washer in a car. Having a handle that folds or collapses can make a pressure washer easier to get in a trunk. It will also help when storing that unit too. This is an option that pretty much only exists on electric pressure washer models.

  12. Accessories

    The more accessories that come with your pressure washer the more washing tasks that you can do with it. As you are shopping, you will notice that some pressure washers come with a wide variety of attachments and others not so much. Although this should never be the main factor in pressure washer selection, it certainly can be a deciding factor between two similar models. Be sure to look closely at what accessories come with your pressure washer to make it more convenient to use.

  13. Onboard Storage

    You don’t want to always be rummaging around your trunk or workshop for loose accessories when using a pressure washer. That’s why it makes it very nice to have a pressure washer with on-board storage. The more secure that onboard accessory storage is the better. That way all the accessories you need for your pressure washer will not fall off when transporting it.

  14. Warranty

    There is a wide variety of different types of warranties that come with pressure washers. Having a good warranty is very desirable when you own a pressure washer. The best warranties are ones that last a long time and include a short money-back guarantee period too. That’s also a sign that a manufacturer thinks that their pressure washer products are well-built. So, just like when you are choosing a car buffer, you need to find the best possible warranty when choosing a pressure washer too.

Electric vs Gas Car Pressure Washers

electric vs gas pressure washer
One hard decision when buying a new pressure washer is whether to buy a gas or electric-powered model. Here is a comparison of the pros and cons of each type of pressure washer to help with that decision.

  1. Electric Pressure Washers


    • They are very lightweight and portable.
    • The technology in them is improving and making them more powerful.
    • They are the more budget-friendly option of the two.
    • These style pressure washers are virtually maintenance-free except for occasional cleaning and lubrication.


    • Less costly models can be underpowered as far as PSI goes. This makes them less versatile than gas-powered pressure washers.
    • Tend to be not as durable as gas pressure washer models.
    • There needs to be a power outlet everywhere that you take them. Power cords can also restrict the freedom of movement that you have with them.
  2. Gas Pressure Washers


    • Usually, they generate more PSI than electric pressure washers. It makes them great for use on pavement, decks, and other tough cleaning jobs.
    • Can be used at remote locations that have no electricity.
    • More freedom of movement because they have no attached power cords.


    • They can be extremely heavy which makes them less portable than electric pressure washers.
    • Gas engines are very noisy when the pressure washer is operating.
    • Have to be careful when using them on automobiles and painted surfaces because of their power.
    • They require more maintenance than electric pressure washers.

Helpful Pressure Washer Terms

It will probably help you when shopping for a new pressure washer to know some of the more familiar terms that people use to describe their features.

 6 Terms of Pressure Washer for Car*

  1. PSI

    Here is one way that the power of a pressure washer is determined. PSI stands for ‘pounds per square inch’ and represents the amount of pressure that pushes the water through a pressure washer hose.

  2. GPM

    This is another factor in determining how powerful any pressure washer you are thinking about buying is. It stands for ‘gallons per minute’ of water flow. The more gallons per minute water flow a pressure washer has the more powerful it is.

  3. Spray Wand

    A spray wand is attached to the water hose and helps the user control how they operate a pressure washer. Usually, they are trigger activated when it comes to starting and stopping the water flow from a pressure washer. The spray wand also has an end that will help it accommodate many different types of nozzles.

  4. Nozzle

    This is the attachment that is placed at the tip of the spray wand. Most pressure washers come with several of them. They adjust and angle the stream of water coming out of the spray wand. The tips are color-coded and pressure washers typically include a 40° (white) nozzle that delivers a flat spray, a 25° (green) nozzle and a 15° (yellow) nozzle that is preferred for washing cars.

  5. Turbo nozzle or turbo tip

    This is a specialized tip that has a very small opening. It creates extra water pressure coming out of the spray wand. It’s used for heavy-duty cleaning jobs.

  6. Wand extension

    This is a spray wand attachment that comes with some pressure washer models. It screws into the spray wand to make it longer so it can reach up higher to do such things as siding and window washing.
    Pressure hose
    This is the hose that is attached to the pressure washer spray wand and the pressure washer itself. It’s what the forcibly pumped water from the pressure washer flows through in order to enable it to do washing and cleaning tasks.

Cleaning Power: PSI and GPM

We have already talked a little about how important it is to know the GPM (gallons per minute of water flow) and PSI (pounds per square inch of water pressure) specs for any pressure washer model that you are thinking about buying. Here is a little bit more about these two critical pressure washer numbers.

If you are just going to use your pressure washer just to clean your car you need between 1200 to 1900 PSI. For comparison sake, a typical garden hose has about 80 PSI. You will need higher PSI than 1900 if you are going to be cleaning concrete or other very dirty surfaces with your new pressure washer.

As long as you have good PSI in your pressure washer, you are guaranteed to have good GPM flow too. Just to be on the safe side here, make sure your new pressure washers GPM is 1.0 to 4.0.

Pressure washing when combined with good detergents (see our car wash soap reviews) and the best car upholstery cleaner, can leave both the inside and the outside of your car looking amazing.

Power Washers Vs. Pressure Washers – What’s the Difference?

Many people wonder what the difference is between a pressure washer and a power washer. It’s a pretty simple answer. Power washers use a combination of high pressure and heated water to get things clean. Pressure washers do not have a heating component to them. They just use the force of the water coming out of them to make washing surfaces easier.

Pros and Cons of Using Pressure Washers on Cars

Here are the good and bad points of using pressure washers on vehicles:


  • There really is no faster way to clean a car. So they are perfect for those that like a clean car but have little extra time to wash it.
  • They save a lot of wear and tear on your body. With the right detergent mix, they make it very easy to get road dirt and grime off of your car. No tedious scrubbing or rubbing is required to get your car’s surface extremely clean.
  • Some states have laws that prohibit the use of using water hoses when cleaning your automobile. There are no laws against using pressure washers to clean your car because they save water while you do it.


  • Pressure washers are so powerful they tend to totally remove the wax finish protectant on any car.
  • If they are used with the wrong tip in combination with too much pressure, they can hurt your car’s finish.
  • You can get hurt using a pressure washer on your car if you are not careful.

Why Pressure Washers Don’t Damage Paintwork if Used Properly

There is a lot of misinformation going around that pressure washers are bad for use on cars. This is entirely not true. The only way you will damage your vehicle using a pressure washer on your car is if you do it without using any common sense. You also need to thoroughly read your pressure washer’s owner’s manual before using it. Sure, if you put a non-restrictive nozzle on the end of a spray wand you can damage your car’s finish. The bigger question is, why would you ever want to do this. It’s the very reason that your pressure washer comes with different tips and different pressure settings. When used according to the manufacturer’s instructions and with common sense, no pressure washer will ever damage your car’s finish.

Everything You Need to Know About Using Washer

  1. How Pressure Washers Work

    The concept of how pressure washers work is actually very simple. There is an incoming water line that feeds water into the machine. Then the motor on the pressure washer, which is electric or gas-powered, increases the force of the incoming water. That higher pressure water then travels through the water pressure hose and into the spray wand. Once the trigger of the spray wand is depressed, the water comes shooting out of the wand with great force. This is why pressure washers do a great job of cleaning and washing cars and other surfaces. That high pressure jetted stream saves a lot of scrubbing and rubbing when it comes to getting surfaces clean.

  2. How to Use A Car Pressure Washer

    It’s pretty easy to clean your car with a good pressure washer. That’s why they are so widely popular for this purpose. If you have a soap dispenser in your pressure washer, soap your car starting at the top and working down. If no soap dispenser, do this with a bucket and large sponge. Some detergents you may have to leave on a few minutes, so make sure to read the instructions. Next, once again working from the top down, rinse your car off. Use the 15° (yellow) nozzle for this. Spend a little long on muddy areas or other areas with high grime buildup. You may even have to use a special car brush to clean tires and get off bugs. Once you are done a good coat of wax is always recommended.
    When you are done cleaning the exterior of your car with your pressure washer, make sure you do the windows too. That will help your car look awesome when it’s done. Use our car window cleaner buying guide to help you find a good streakless window cleaner.

  3. Safety Tips When Using A Pressure Washer

    You always have to keep safety in mind whenever you are using your pressure washer. Never get the spray too close to your body or point it at someone else. This can cause cuts and skin irritations if you have a strong pressure washer. When working with gas pressure washers don’t get too close to their hot exhaust. Also don’t leave a gas can near the pressure washer when it’s running or it could ignite. For electric pressure washers, we recommend you never run them unless plugged into a GFI outlet or they have a GFI attached to their power cord.

Pressure Washer FAQs

Here are some frequently asked questions that we get about pressure washers:

  • Question: What is the red nozzle that comes with my pressure washer best used for?
    Answer: We are glad you asked this question because operators need to use the red nozzle with extreme caution. That’s because it’s what’s known as a 0° nozzle. It sprays straight and does not cut down the pressure at all. It’s so powerful it can take the paint off your car’s delicate finish and leave gouges in the wood. Use it on only the toughest jobs like paint stripping or cleaning non-painted solid metal objects.
  • Question: Can I use my pressure washer to strip paint off of wood?
    Answer: The answer here is yeas but you have to be careful. You need a nozzle that takes off the paint without damaging the wood underneath. Start with lower pressure nozzles and work your way up until you find a nozzle that works.
  • Question: If I am just doing light duty cleaning and car washing with my new pressure washer, should I get a gas-powered or electric-powered pressure washer?
    Answer: The answer here is definitely an electric pressure washer. It will clean everything as mentioned and be more portable and less expensive to purchase.
