What is an Electric Pressure Washer?
Pressure washing is also known as power washing – the use of high pressured water spray to get rid of any mold, dust, dirt, mud, loose paint, mildew or chewing gum from the surfaces and objects such as windows, walls, ceiling, patios, building, etc.
A pressure washer is a water machine that dispenses the water at high pressure. That highly-pressured water spray is used to remove tough stains or even the mold that collects around the house. The machine can be used practically on all surfaces that can be soaked, which makes it a great way to effectively clean the house.
The pressure washer machine can be used for domestic and industrial use. There are different water pressures for various surfaces – you won’t be using the same water pressure for the glass window or the concrete driveway.
The convenient availability of the pressure machine is making the process more popular and easy around the house. People find it more efficient and easy to use the machine and clean up around the house without much effort – no more scrubbing, or peeling, or hard work.
Over time, these machines have made their way in peoples’ houses rather than just being used for commercial purposes. Companies have now made different pressured systems to suit the domestic lifestyle and the domestic surfaces where the product will be used.
How Do Electric Power Washers Work?
Let’s face it – surfaces get dirty all the time, whether it’s from your handiwork, pets, kids, their chalk art on the concrete, birds targeting your car, or anything in between. If you have some serious cleaning to do and don’t want to pay for professional cleaners over and over again, it’s definitely wise to invest in a powerful, electric pressure washer.
There are some key terminologies you have to understand before you start shopping for the power washer that will meet your needs. So, let’s see how a power washer actually works.
The technology behind the power washers is simple – the water is sprayed at very high pressure and directed towards the surface you want to clean. The motors have at least 100 to 200 times more pressure than the air that surrounds us. The 1500-4500 pounds per square inch (PSI) water pressure helps fight the toughest of stains. The light and medium cleaning can be done with the water pressures from 1500 to 2000 PSI. That is generally enough to wash patios, driveways, cars, grills and to accomplish other simple residential cleaning feats. Heavy-duty cleaning requires generally PSI of 1900 and up.
If you want to clean a workshop, a garage, or any other highly stained and greasy area, you should choose the power washer with a soap dispenser or a foamer.
This pressure is going to be meaningless if the hose doesn’t have the appropriate diameter to throw the water. It refers to the gallons per minute (GPM) and the larger the number, the faster the cleaning process.
To determine the cleaning power (CP) of a pressure washer, just multiply the PSI number with GPM number and you will get what you need to look at when buying such a machine.
The simple formula is CP = PSI x GPM
What Makes Electric Pressure Washers Powerful?
Simply mentioning PSI, GPM or CP just won’t cut it, because those numbers do not exactly have use outside of this context, and the frame of reference is not that easy to understand. Getting the highest number is important, yes, but there’s more to it than just pointing at digits.
The first power element of an electric pressure washer is its motor, of course. Motors are there to power the water pump and make the whole liquid circulation system going. Additionally, electric motors are known for being compact and lightweight, which is always a plus when we talk about the machines that you need to haul all over the yard.
But what really makes an electric pressure washer powerful is the engineering – specifically the way its power is utilized. Just having an ultra-high PSI washer can be futile if the water flow is not used in the best possible way. That’s where every washer model tends to differentiate. There are many factors that can affect the end results of cleaning potential, besides raw power. Spray gun quality, power adjustment, pressure hose type. These are just some examples of what really makes these electric pressure washers better or worse, depending on your requirements. But of course, if you want the maximum power, you should consider having a look at gas pressure washers.
Main Parts Of Pressure Washers
Like any machine, the pressure washer is made up of main parts that make the machine running efficiently and without a hitch. The following parts are the main parts that can be found in any standard pressure washer machine:
1. Water inlet
The water inlet is a hose that is connected to the main water supply. The inlet has a filter so that contaminated water can be filtered out and does not cause a hindrance to the machine while running.
It’s important to change the filter regularly, otherwise, the pressure may cause the machine to blast on the other end and cause damage.
2. Electric motor
An engine is very important to keep the machine running, naturally. Best electric pressure washers at home have the electric shock safety measures because, well, they run on electricity – mixing it with water can be quite dangerous. Most of the pressure washers are intended for home use so they don’t draw too much power. Meanwhile, the industrial pressure washers require a larger amount of electricity, naturally. The more powerful the motor on the power washer, the faster will the jets shoot the water under pressure.
3. Water pump
The water pump works as the heart of the power washer. It works under the basic principle of the hand-operated water ground pumps, except that it uses the electric motor.
The engine sucks the water from one way and pushes out the water at high pressure in return. These water pumps are nothing like the regular pumps. They are manufactured to withstand 1-2 gallons per minute.
4. High-pressure hose
The high-pressure hose is the tube from where the water is shot at a pressure. The tube is made with care to help in dealing with the high pressure of the water because a regular hose will just break or burst. The material used for high-pressure hoses is a high-density plastic and it is reinforced with a wire mesh.
Some machines do not come with a hose which can be a problem since it is hard to find the one that is perfect for your machine and your intended use. The nozzles also play an important part as they are used to determine the angle of the water that’s coming out of the pressure hose. The angles make all the difference in how that water pressure is used for cleaning.
What Can You Clean With Pressure Washers?
Pressure washers are handy to have if you don’t need heavier cleaning. Forget about the paint stripping or anything remotely heavy-duty. So, with a compact, hand carry pressure washer you can clean the following surfaces:
Pressure washers are perfect for washing windows around the house. You don’t need the strong pressure output for this task, and any type of nozzle will work okay if you reduce the pressure.
If we are talking about the regular deck cleaning and maintenance, then an electric power washer can handle such a chore. If there are heavy stains, crusty buildups, and severe muck and grime, then you should choose something from the most powerful pressure washers.
3. Farm Produce
Some people even use these power washers to rinse their harvested produce. The pressure output isn’t large enough to hurt the vegetables, but it cleans them thoroughly. People often use it for carrots and potato. Neat!
Choose the more powerful pressure washers among these compact ones, and you will get a unit that will help you clean your car quickly and with ease.
5. Bikes and bicycles
Can you imagine all those wires and small surfaces that get packed with dirt if you leave your bike or bicycle in the garage? It could take hours to wash everything down – or it could take minutes if you use a power washer to clean your bike.
Pressure washers let you wash plants if you reduce the pressure output, use right chemical solutions and use a light flow. Sure, you can do that with a regular hose, but if you are already hooking up the power washer, this is an additional task that you can accomplish.
Pressure washers can perfectly help you with regular patio cleaning and maintenance unless you have too heavy stains or built-up moss.
If you want to keep your boat clean, then a pressure washer can easily help you with the mildew and muck build-up. This type of job is perfect for smaller units because you don’t need a powerful pressure to remove light staining.
Again, light dirt and wear and tear can be easily removed with these units. But don’t expect all of them to be able to prepare surfaces for painting. You would need something more powerful than that, with an output larger than 3000 PSI. If the storm hits, the leftover leaves and muck can be easily cleaned with a simple power washer.
10. Outdoor furniture
Outdoor furniture is usually built from light materials and plastics that can withstand outdoor weather. That usually means that that same furniture has been left outside, so the dust and dirt have left their mark. Since we are still talking about easily breakable stuff, too high of pressure can leave you, well, without your furniture. A power washer with an adjustable pressure output can be helpful for this cleaning job.
11. Other heavy units
Use a pressure washer to quickly wash your lawnmower. Especially if it wilted in the garage entire winter and racked up dust in the meantime. A couple of spray gun moves and it will be as good as new. Otherwise, cleaning it with soap and a bucket of water can take you hours.
Summertime is perfect for yard parties, but who will clean the nasty, greasy grill? A simple power washer can deal with it in no time. Imagine powering up a standard heavy duty washer just for BBQ maintenance. It would take you 30 minutes to connect the washer and approximately 30 seconds to clean the grill.
Electric Pressure Washer Buying Guide
There is a huge variety of pressure washers available on the market and buying the right one can be an irksome task – what if you bought one that simply isn’t powerful enough to help you clean around the house? This is why we have created this beginner’s buying guide and give some tips for using pressure washers to cover your requirements.
1. Power Source
The first decision you have to make is to determine whether you need a gas or electric one. Electric pressure washers are better for domestic use. They are quieter and more efficient as compared to their counterparts. They are usually smaller in size too and are best suited for small-scale jobs.
2. Cleaning Power
Pressure washers have a huge variety when we consider their cleaning power. To choose a pressure washer you must know its purpose. The primary objective is cleaning and there is a vast number of additional parts that will make the job easier for you. Anything over 2000 PSI is good for bigger jobs, larger surfaces, and hard-core stains.
The light-duty machine has a lower flow rate compared to medium or heavy-duty machines. High durability is a primary feature of the commercial grade washer. Light duty machines are not designed to take a toll on a daily basis.
3. Parts & Accessories
If you are buying your power washer from a credible brand, then you will get all the essentials with a standard purchase. Your washer will come with a variety of nozzles that will allow you to adjust the water spray and power according to your needs. In addition to that, every good power washer for residential use will contain a lance, a gun, durable hose, and hose reel, as well as detergents or other chemicals for your first wash.
4. Pick The Nozzle
The nozzle makes a ton of difference when using a power washer. There are many different types of nozzles which are used for various purposes. However, if you don’t know which nozzle to choose, the multi-purpose nozzle can be your savior. If you see that it isn’t getting the job done, then, read the manual again and try using a different type of nozzle.
5. Length Of The Cord And Hose
The length of the cord is fairly important if you are going for an electric machine. Get a power washer with at least 30 feet of cord, so that you can get around with ease. You will have to decide the length according to your use and the size of the area you are planning to clean with a power washer.
The hose length is also important because you want to hold it firmly in the back so you don’t injure yourself. Some hoses are expandable, which allows you to reach tough and otherwise unreachable spots. The usage will again, depend on the place where you want to use the machine.
6. Select The Pressure Settings
You will need this feature especially if you are using the system around your house. Some machines have the option to select the power of water pressure, which is useful for residential cleaning.
Selecting the right pressure settings helps in saving the time, the nozzle and the surface that you will be using the machine on.
7. Auto Shut Down
Most of the pressure washers have an automatic shutdown process that helps with ensuring that the machine isn’t on when you don’t want it to. The motor will shut down when it hasn’t been used for a while so that even if you forget, the machine will remember it for you – saving you from any potential accidents.
8. Adjustable Power Management
A topic that deserves a special mention is power management. This includes every model that has some form of PSI control at the motor side, and not at the end of the spray wand. These electric pressure washers are powerful, and the last thing you want is to damage a good piece of patio furniture or the wood finish on your porch.
Controlling the power output can be useful in more than one way. It is certain that you will not need the full power turned on all the time, and the best things about controlling the PSI are electricity and water saving. Once you get the hang of it, you will know when to bump up the power and when to go low. All it takes is a little practice.
If absolute control is what you’re after, then we recommend getting a model that has power regulation both at the motor side and at the spray wand side. By utilizing each feature at the same time, you can finely tune the stream of pressurized water, and avoid any material damages and/or unnecessary waste of resources.
How To Set Up A Pressure Washer?
You can set up your pressure washer by following these six easy steps below:
- First, link your high-pressure hose to the pressure washer if it isn’t linked already.
- Then, insert that hose into the high-pressure inlet which is located on top of the water inlet. Make sure to secure it completely.
- After that, connect the garden hose and thread a coupler link onto it.
- Next, set up your spray gun and connect the extension lance to it.
- In the end, link your pressure washer with a power source.
- Then turn the water faucet on. Make sure not to run the high-pressure water pump without proper water supply or it will damage the pump.
All that is left is to turn on the power washer and begin the cleaning.
Pressure Washer Troubleshooting
Following are the most common issues that can happen when using pressure washers:
- When dealing with a low-pressure issue, unlink the garden hose and ensure the full water pressure is coming from the tap.
- When there is no pressure at all, then adjust the unloader screw and also check for damaged seals or springs.
- When there is a pulsing pressure, disassemble the pump and replace or even clean components of the inlet.
- In case the pressure spikes repeatedly, ensure to make adjustments to the unloader for appropriate pressure.
- If the pressure drops after a short while, then clear the nozzle with help of a needle.
- If your pressure washer is not cleaning the surface, then switch to a spray nozzle with a higher pressure. However, still, check the manual to see whether the surface can withstand the higher pressure.
- If you see the water leaking from the pump, check your warranty and return or replace your machine.
- If the water is leaking from the garden hose, then connect your machine properly.
- If there is a leakage of spray, you should then replace the o-ring or return the hose and get a new one.
- If the oil is dripping from the engine, then make sure to replace the seals under warranty.
- If you see water in the oil, then your machine might have been worn out or pistons were broken, so you should ask for a repair under warranty.
- If the chemical injector is not working, then try to insert the black soaping nozzle.
- In case of excessive noise, check and clean your machine or replace it under warranty.
FAQ About Electric Pressure Washers
1. Does The Washer Have Enough Pressure To Damage Car Paint?
Yes, of course, power washers can damage the car paint if used improperly. That amount of pressure exerted is very high and it can damage a solid surface easily. It can even dent your car! So, make sure that the power washer is powerful enough to clean all the surfaces you want, but pay attention to get a power washer with the adjustable pressure settings.
You should check the manual thoroughly. Furthermore, ensure that you have the right nozzle to support the right pressure. Never make the mistake of being too close to the surface that needs to be cleaned, because some surfaces can be damaged easily.
2. What Accessories Can I Get With My Pressure Washer?
A pressure washer comes with a variety of different accessories. One of the essential accessories is filters. You will need the filters to ensure that your system never clogs and bursts. Even if it gets clogged, you will be ready for it.
You can also get patio cleaners and other types of hoses to help clean different surfaces with the pressure washer machine.
3. How To Decide Which Pressure Washer To Use?
First of all, you have to understand where you are going to use your pressure washer.
A machine that you will use at your home doesn’t have to be that powerful, and anything less than 3000 PSI, for example, a portable pressure washer one will do the trick.
For commercial use, you will need a washer that goes over 3000 PSI due to different conditions and a variety of surfaces.
Furthermore, you must consider what you want to clean. If you are looking to rinse away dust, dirt or grime at home then a unit with a relatively low pressure of 2500 PSI is good enough. If you are dealing with mold and mildew gathered on the concrete, then you will require higher pressure.
For commercial use, the cleaning area increases considerably, and you don’t want to spend your whole day cleaning around because you have other jobs at hand too. So, in that case, you will need a machine with better GPM and anything over 2.0 will work wonders in that case.
4. How Crucial Is To Consider The Flow Rate Of The Machine?
While rushing out to purchase a good quality power washer, you have to consider the water flow rate of the machine. The more the machine blasts out water, the easier and quicker it is for you to clean the surface effectively.
Considering the size and weight of the power washer is also important. You don’t want it to be too heavy to carry from one place to another.
5. How Much Water Is Used For Pressure Washing?
There is a common misconception that a regular garden hose consumes less water as compared to the pressure washer, but it is quite the opposite. A pressure washer machine uses about 2 gallons of water per minute whereas a garden hose uses 20! Using pressure washers helps with water saving.
The amount of water required for a job is based on the nature of the job at hand. For instance, smaller jobs such as washing a car need light duty pressure washer with water pressure ranging from 1400 to 1750 PSI and flow rate ranging from 1.4 to 1.6 GPM.
If you are looking to clean your driveway then you will need a medium-duty pressure washer with PSI ranging from 2300 to 2500 and GPM ranging from 2.2 to 2.3. This might sound like plenty but lightweight machines consume 685 times less water as compared to your garden hose.
6. What Are The Different Pressure Washer Nozzle Types?
There are a number of nozzle types used for different purposes altogether. The nozzle type is measured according to the degrees that it is positioned. The low-pressure nozzle is perfect to add soaps or detergents and ease the cleaning process.
The nozzle of 40 degrees is made for surfaces that tend to be damaged easily – like windows and glass doors. The next one is the 25 degrees nozzle which is for general residential cleaning and has a wide variety of use.
For heavy duty cleaning and washing, a nozzle of 15 degrees is the most preferred and perfect for the job. The zero-degree nozzles are mostly used for industrial cleaning. It is the toughest nozzle for using because it can cause serious damage if there’s contact with skin.
- 0° spray nozzle – red color (not recommended for wood but suitable for concrete and metal)
- 15° spray nozzle – yellow color (recommended for concrete)
- 25° spray nozzle – green color (recommended for wood and general washing purposes)
- 40° spray nozzle – white color (recommended for rinsing purposes)
7. How Much Should A Power Washer Weigh?
An average power washer machine can weigh from anywhere around 25 pounds to over 100 pounds. The weight of a machine entirely depends upon its capacity and the motor fitted into it. Most of the domestic machines weigh approximately 25 to 50 pounds while the commercial units are heavy – they exceed the 50-pound limit.
8. Why Would I Need An Extendable Hose?
Extendable hoses are necessary when you want to clean far-reaching areas, and instead of going near them and endangering your health, you can just extend the hose. This hose can help you avoid accidentally blasting water on you and causing tissue damage.
An extendable hose can also help you reach higher surfaces that you would like to clean with your pressure cleaner – like gutters for example.
9. How Should I Store My Power Washer?
Your power washer is a high-powered machine that needs to be stored carefully. If it is electric, then make sure it is entirely unplugged and wrapped up properly. Keep it in a dry place to preserve its function.
Make sure that the machine is not at all reachable to children even when it’s not in use, or else there can be serious consequences.
10. What Chemicals Can Be Used?
There are various types of soaps and detergents that you can use with your power washer and each of them are designed to serve a different purpose.
For instance, there is a separate detergent to wash your car and an entirely different one to clean your driveway.
You can find sanitizers to kill most of the bacteria quickly, cleaners to remove dirt as well as disinfectants that kill all kinds of microorganisms.
You can buy these chemicals separately and some machine manufacturers sell them with the product as complementary goods. Manufacturers of these chemicals label them based on recommended surface and use.
- You can use vinegar for cleaning countertops, or windows. It can also be used for polishing surfaces, everything from bronze heirlooms to brass door handles.
- Citric acid is better suited for concrete driveways and wooden areas.
- Oxalic acid works well to remove the rust from various surfaces.
- Bleach goes well as an aggressive sanitizer or a disinfectant because it is made of sodium hypochlorite and sodium hydroxide. Use it with caution.
- Sodium Hypochlorite serves well as a stain remover and a powerful disinfectant.
- Sodium Hydroxide, which is also known as caustic, can dissolve grease, fats and is commonly used for steel and glass.
- Ammonia is a common stainless steel and glass cleaner.
- Potassium Hydroxide is used to make liquid soap for cleaning purposes.
11. What Are The Potential Risks Associated With Pressure Washers?
There are various potential risks associated with pressure washers. A high amount of water pressure created by these machines can cut through your flesh and can result in a serious injury. These machines can also cause high-pressure water ingestion which is extremely dangerous.
Some people think that water cannot cause damage, but you should bear in mind that, regardless of the type of chemical, if it is sprayed at high pressure it can cause severe damage. Don’t forget to use safety gear such as long pants, helmets, ear protection, glasses, gloves, and boots when dealing with pressure washers.
Apart from that, excessive water pressure can also damage the surface on which it is used. Therefore it’s vital to understand the color coding of nozzles.
12. What Are The Different Types Of Pumps In Power Washers
Different companies use different types of pumps and these pumps also vary from one machine to another. There are three broad categories: an axial cam pump, a triplex plunger pump, and a wobble pump.
12.1 Axial cam pump
This type of pump can work well with high GPM and PSI. It’s an intermediate level pump that operates better than a wobble variant because the pistons rotate around the swash plate. This plate strokes the piston while the piston does all the sucking up of water from one side to another.
The plate rotates around the same axis as the directly connected drive shaft. It has a lifespan of 500 to 800 hours and it goes well with a 3500 PSI machine.
12.2 Triplex plunger pump
Triplex plunger pump can run for thousands of hours and doesn’t need any maintenance. It can tolerate high pressures and is used in most professional grade machines. It operates just like a car engine where its pistons suck up water and push it with each stroke.
Moreover, it has low RPM and for this reason, it runs cooler than engines and you can do most of the repairs and replacement with ease. Most of the machines with 3000 PSI capacity run with this pump.
12.3 Wobble pump
There is a wobble plate in this pump that is directly linked to the shaft and it pushes the piston back and forth enabling it to suck and throw the water with great force. These pumps work great with 2500 PSI machines or low. Wobble pumps are sealed before they come out of the factory for selling purposes.
13. Can I let my electric pressure washer use hot/warm water?
Some models allow it, and some don’t, so feel free to check the manual. However, even though hot water sounds like a logical choice for better cleaning performance, it will not yield any significantly better results. Using hot water is only good in certain cases of really stubborn stains made by grease or oil. The pressure exerted by these machines is powerful enough to tackle anything else, regardless of water temperature.

Now you have read all the electric pressure washer reviews along with a simple buying guide that contained all the necessary information. Every product has its own pros and cons so you will have to think about what will for you, depending on the surfaces and the type of cleaning you want to accomplish.
Some people require a water pressure of 1600 PSI for regular domestic use, while others who have large garages and greasy grills will require a pressure of 2500 PSI. When buying any pressure washer, you should always take into consideration the nozzle type and the cord length. These two seemingly unimportant parts can turn out to be deal breakers.
