Best Electric Pressure Washers

Best Electric Pressure Washers

If you’ve ever tried washing greasy surfaces with a normal hose or simply removing all the dirt from carpets and your car, you know how difficult and time consuming it can be. Therefore we have drawn up a list of the best electric pressure washers.

So if you want to equip yourself with the necessary knowledge, we’re right behind you. Stay close to us, read our electric pressure washer reviews and buying guide, and learn how to make a decision. Let’s get to the bottom of this.

What is an electric pressure washer?

The electric pressure washer – the use of a high-pressure water jet to remove mold, dust, dirt, loose paint, mildew, or chewing gum from surfaces and objects such as windows, walls, ceilings, yards, buildings, and so on.

A high pressure washer is a water machine that delivers water under high pressure. This high-pressure sprayer is used to remove hard spots or even mould that has accumulated throughout the house. The device can be used on almost any damp surface and is therefore an excellent way to effectively clean your home.

The high-pressure cleaner can be used at home as well as in industry. There are different water pressures for different surfaces – you don’t use the same water pressure for a glass window or a concrete track.

Easy access to the electric pressure washer machine makes the process more popular and easier to use at home. People find it more efficient and easier to use and clean throughout the house with little effort – no more washing, cleaning or hard work.

Over time, these machines penetrate people’s homes rather than being used for commercial purposes. Companies are currently producing various pressure washer systems adapted to the domestic lifestyle and the surfaces on which the product is to be used.

10 Best Electric Pressure Washers

How does a electric pressure washers work?

Let’s face it: surfaces are getting dirty, whether it’s your hands, pets, children, chalk drawings on concrete, birds pointing at your car, or something in between. If you have a serious cleaning job to do and don’t want to keep paying for professional cleaning, it’s certainly advisable to invest in a powerful electric high pressure cleaner.

There are a few key concepts you need to understand before looking for electric pressure washers that meet your needs. Let’s see how the electric car wash really works.

The technology of pressure washers is simple: water is sprayed under very high pressure and directed towards the surface to be cleaned. The pressure of the engine is at least 100 to 200 times higher than the pressure of the air around us. A water pressure of 1500-4500 psi (PSI) helps combat the strongest points. Simple and average cleaning can be carried out at water pressures from 1500 to 2000 PSI. This is usually enough for washing patios, driveways, cars, grills and other simple household cleaning jobs. A PSI of 1900 or higher is generally required for high-quality cleaning.

If you want to clean your workshop, garage or other very greasy place, you should opt for an electric wash with soap or foam dispenser.

This pressure is useless if the hose is not the right diameter to drain the water. These are gallons per minute (GPM) and the higher the number, the faster the cleaning process.

To determine the cleaning capacity (CP) of a pressure washer, simply multiply the PSI number by the GPM number and you will get what you need to consider when purchasing a pressure washer.

Simple formula – CP = PSI x GPM

The Ultimate Guide to Selecting the Electric Pressure Washer

The Ultimate Guide to Selecting the Electric Pressure Washer

Main components of high-pressure washers

Like any other machine, the high pressure washer consists of the most important components that ensure efficient operation of the machine without coupling. The following parts are the most important parts that can be found in any standard machine with a high pressure washer:

1. Water supply

The water supply is a pipe connected to the main water source. The inlet connection is equipped with a filter for filtering dirty water and does not interfere with the operation of the machine.

It is important to change the filter regularly, otherwise the pressure may explode and damage the machine on the other side.

2. Electric motor

The engine is of course very important for the operation of the machine. The best electric washing machines in the house have safety measures in case of an electric shock because they run on electricity – mixing with water can be very dangerous. Most pressure washers are designed for domestic use, so they do not consume too much energy. In the meantime, industrial high-pressure cleaners obviously need more electricity. The more powerful the engine of the washing machine, the faster the nozzles are thrown into the pressurized water.

3. Water pump

The water pump works like the heart of a washing machine. It works according to the basic principle of manual submersible water pumps, with the difference that it uses an electric motor.

The engine sucks the water in one direction and pushes it with high pressure in the other direction. These water pumps do not look like normal pumps. They are produced with a capacity of 1 to 2 gallons per minute.

4. High pressure hose

A high pressure hose is a tube from which water is discharged under pressure. The hose has been carefully manufactured to withstand high water pressure, because a normal hose will simply tear or break. The material used for the high-pressure wash hoses is a high-density plastic reinforced with wire mesh.

Some machines do not come with a hose, which can be a problem because it is difficult to find a hose that fits your machine and application perfectly. Nozzles also play an important role because they are used to determine the angle at which the water comes out of the pressure hose. The angular positions determine how the water pressure is used for cleaning.

The most powerful electrical pressure washers

The most powerful electrical pressure washers

As you have probably already concluded, powerful electric high-pressure cleaners offer many possibilities. Each model has something unique or a certain combination of standard features, so it is essential to know which features are involved. In the following paragraphs we will talk about the complicated details and everything worthy of your attention for these powerful electrical machines.

1. PSI and GPM, what do they mean?

As you can see above, each model is evaluated with the PSI and the GPM. In short, PSI and GPM are pounds per square inch and gallons per minute, respectively. Both specifications are equally important: the first describes the gross performance of the high pressure cleaner, while the GPM determines the amount of water needed to maintain that high pressure.

Not everyone is still an engineer and knowing the exact units and quantifiable data should not be an obstacle. The calculation is quite simple, with one principle: the larger the number, the more powerful the high-pressure cleaner.

However, it must be taken into account that higher performance of the PSI and GPM requires more electricity and more water/detergent. So if you want to use a washing machine that is easy to use and clean, you should consider buying a model with adjustable power.

There is an easier way to avoid the numbers and decide how powerful a pressure washer is. It’s called CP or cleaning power. This is the total power a machine can generate, and to get this number you just need to multiply the ISP and the GPM. It’s so simple.

2. What makes electric pressure washers powerful?

What makes electric pressure washers powerful?

Just mentioning the PSI, GPM or PC is not enough, because outside this context the figures are not exactly usable and the frame of reference is not so easy to understand. Reaching the highest number is important, yes, but it’s not just a matter of referring to numbers.

The first drive element of an electric high-pressure washer is of course the motor. Electric motors power the water pump and drive the entire fluid circulation system. In addition, electric motors are known for their compact size and light weight, which is always an advantage when it comes to cars that have to be transported on the farm.

But what makes an electric pressure washer really powerful is the technology – the way the energy is used. Just having a very high PSI scrubber/dryer can be useless if the water flow is not used optimally. Here, each model of washing machine is usually differentiated. In addition to the gross energy, there are many factors that can influence the end result of a possible renovation. Spray gun quality, power control, pressure hose type. These are just a few examples of what really makes these electric high pressure cleaners better or worse, depending on your needs. But if you want maximum performance, you should of course think about consulting our reports on gas cylinder washers.

3. Advantages of the powerful electric pressure washers

Advantages of the powerful electric pressure washers

Although there is a lively discussion about the environmental factors surrounding each type of high pressure cleaner, the electrical system is guaranteed to have advantages.

3.1 Service

Whatever the size and power of the engine, chances are there’s nothing you can do to keep them inside. These engines are hermetically sealed and contain no oil, so no lubrication is needed. On some models, and only if the manufacturer commits, you should take short breaks during cleaning to allow the engine to cool down a little.

If you are concerned about a breakage, consider a water-cooled high-pressure cleaner. These models are known for their long working hours, simply because they use the water circulating in the washing machine as a coolant.
3.2 Noise

Another important factor that people tend to forget is the noise level. Yeah, you wash the outside, but nobody likes to wear earplugs. In general, electric motors are known to run at a standstill unless you maximize PSI power when working with stains that are difficult to remove.

It’s the same here: If you are concerned about high noise levels, an electric air scrubber with adjustable settings may be the safest solution.
3.3 Transferability

When we said that there are great technical solutions to develop these powerful electric high-pressure cleaners, the first thing that came to mind was the size of these models. They are compact and portable, do not weigh much, but can defy any stain that needs to be cleaned.

Different manufacturers have developed different ways to increase the portability of washing machines, but the vast majority have common solutions:

  • The hose reel is a large wheel at the top of the unit that keeps the high-pressure hose in the ideal position when not in use. It protects the hose against simultaneous entanglement and suffocation, which is very important because of the pressure in the hose. Devices equipped with hose reels do not tend to bend the hoses like models that do not.
  • Two-wheeler system – almost all electric models have a kind of two-wheeler system. Some have large wheels designed to climb ladders when necessary, others have small wheels available for flat surfaces. In any case, you will have no problem moving the yard or the driveway.
  • Robust and light body – alongside the engine itself, one of the most important features is a body that holds everything together. The smallest models of high pressure washers have only a simple steel support rail. However, it is not uncommon to see an electric high-pressure cleaner with a welded steel frame. You have enough to make the model solid and not much to make it too heavy.

4. What type of equipment can I expect from a powerful electric sink?

What type of equipment can I expect from a powerful electric sink?

There are many ways to realise the full potential of a powerful set of electric high pressure cleaners. The energy provided by these machines can best be used with the equipment they have on board or mounted on the side. You may have noticed that no high-pressure cleaner is supplied without equipment and that a list of items is always included in the delivery. So let’s see what kind of material to look for.

4.1 Robust high pressure hose

The bread and oil of a well-designed pressure washer is a hose that transfers the pressure from the water pump to the spray bar. According to some users of professional tools, the quality of the hose is just as important as the performance of a pressure washer. The explanation for this bold statement is that, regardless of the PSI and GPM produced by the engine, if the hose can withstand it, it’s all for nothing.

The high-pressure hoses supplied with the high-pressure cleaners are manufactured in several layers. Often there will be some kind of cable network inside that will keep the elbow resistant. Additional layers of synthetic materials are available to prevent corrosion and damage.

With regard to the length of a high-pressure hose, the following rule applies: the longer the hose, the better, but not in all cases. Longer hoses are more comfortable, but the longer the hose, the higher the power should be adjusted. After all, water under pressure has to travel a greater distance without loss of pressure. Therefore, the optimal length of the high pressure hose should be between 15 and 25 feet.
4.2 Aerosols

At the end of each tube there is a deflection system, often in the form of a spraying pliers. The heart of the spray bar is a hollow tube which must be perfectly adapted to the high-pressure hose. Most models of spray poles have a so-called trigger or pressure lever at the bottom. It is always well placed under the palm of your hand so that you can regulate the flow of water under pressure.

It is customary to have a rotary valve on the rod that regulates the angle and width of the water flow and thus directly regulates the cleaning capacity. That’s why some models are equipped with different detachable sticks, with a kind of turbo stick for maximum pressure and minimum angles.

However, a stick with interchangeable tips is becoming more and more popular with every new model, which brings us to the next item of equipment.

4.3 Nozzles

The nozzle is just as powerful as the adjustable rods. The nozzles are supplied in standard sets, max. 5 pieces:

  • The soap nozzle is the one with the least cleaning power, simply because it has a different task. This nozzle is designed so that the detergent from the detergent tank is dosed as much as possible with a minimum of losses. Used when it is necessary to absorb stubborn stains in the soap to remove them.
  • The 0-degree nozzle is the most powerful of all. It concentrates the water flow in a single pipe, using all the power of a powerful electric high-pressure cleaner.
  • 15 degree nozzle – if you need both power and cleaning speed, a nozzle of this width is best suited for concrete and metal surfaces. If the nozzle is set to a high level, you may damage softer materials such as wood.
  • The 25-degree nozzle is the most versatile of the standard set. It can provide more power, with a sufficiently wide spread to prevent damage to the contact surface.
  • 40 degree nozzle – often not included, this width is used when a large area needs to be covered in a short time. Remember that no total explosion can occur regardless of the nominal capacity of the pressure washer.

With training on when and how to use each nozzle, you can get the most out of your high-pressure cleaning models.

4.4 Adaptable energy management

The theme of energy management deserves a special mention. This includes all models that have some form of PSI control on the motor side and not at the end of the spray bar. These electric high-pressure cleaners are powerful, and the last thing you want to do is damage beautiful patio furniture or the woodwork on your porch.

The management of the output power can be useful in more than one way. I’m sure you don’t have to turn on the power all the time, and the best way to manage a PSI is to save energy and water. Once you get used to it, you know when to increase performance and when to decrease it. All it takes is a little practice.

If you need absolute control, we recommend a model with power control on both the motor and spray side. By using all functions at the same time, you can accurately control the flow of pressurized water to prevent material damage and/or unnecessary waste of resources.

5. Cleaning capacity

Pressure washers are very diverse in terms of their cleaning power. To choose a puck with pressure, you need to know its purpose. The main purpose is cleaning, and there are many extra details that will make your job easier. Anything above 2000 PSI is well suited for large orders, large areas and hard points.

The light machine has a lower consumption than medium and heavy machines. High wear resistance is an important part of high quality commercial high-pressure cleaners. Lightweight machines are not designed for daily use.

6. Automatic stop

Most pressure washers have an automatic shutdown procedure that ensures that the machine does not start if you do not want it to. The engine shuts down if it has not been used for a certain period of time. Even if you forget, the car will remember it for you and protect you from possible accidents.

What can I clean with powerful pressure washers?

We talked about all the mechanisms and systems that make these gardening machines great. But now it’s time to talk about the results. You can clean cars, bicycles, boats, railways, farms, bridges, plants, patios, etc. It is easier to understand these options from the interface point of view. Let’s start with the lightest material and make our way to the top.

Total Time: 3 minutes

1. Wooden surfaces

Backrests, terraces, tables and chairs for outdoor relaxation, as you call it. With a sufficiently large spray angle, you can treat and clean wooden surfaces in a matter of minutes. Remember the softness of the wood before you come into contact with the pressure washer, as you may damage it.

For softer woods or planks with little or no protective coating, use a wide-angle nozzle/bar or install an energy-efficient washing machine. And in the case of hardwood or heavily protected wooden surfaces, you can stand securely on the slot and use the nozzle at 15 degrees. And the best thing is that you can now take out the annoying cannon that has been piling up between the shelves for centuries.

If you don’t know how to approach and adjust the angle of adjustment and power, try removing a small part of the page and see what happens. A few square centimetres should be enough.

2. Ceramic and mineral surfaces

Ceramic and mineral surfaces

One of the best applications of a powerful electric pressure washer is cleaning in and around the pool. Collecting between the tiles and cleaning the dirt that accumulates during the season is extremely pleasant and incredibly hygienic. Check the effect on a tile before you start.

By mineral surfaces we mean any kind of stone or marble. The mineral surfaces of our garden and terrace furniture have a tendency to develop mould because they consist mainly of stone – the natural habitat of fungi and lichens. Place your pressure washer on a larger unit and get rid of it within seconds.

3. Metal and concrete surfaces

Metal and concrete surfaces

Finally, the highest settings and narrowest nozzles are used for surfaces that are tougher and dirtier than the rest of the yard. Roads, rainwater drainage, garage doors, etc. It’s a pleasure to check a little. The risk of damage to these surfaces is minimal, so be prepared for longer pressure washes.

4. Non-conventional waxes

According to the standard specifications, it is worth mentioning some rare surfaces that can be cleaned with electric pressure washing: Washing of exterior windows, cleaning of gutters, restoration of old and greasy grids, removal of paint, etc. You know what I mean. You just need to experiment a little.

You can also find more information in our reviews of vinyl upholstery cleaners.

How do I set up a high-pressure car wash?

You can adjust your pressure washer by following these six steps:

  • First connect the high-pressure hose to the pressure washer, if it is not already connected.
  • Then insert this hose into the high-pressure fitting at the water inlet. Make sure it’s fully secured.
  • Then connect the garden hose and tighten the connection sleeve.
  • Then install the gun and connect the Extension Gloss to it.
  • Finally, connect your pressure washer to the power supply.
  • Then open the water tap. Make sure that the high-pressure water pump does not operate without sufficient water supply, otherwise the pump may be damaged.

All you have to do is turn on the electric washing machine and start cleaning.

Troubleshooting electric pressure washers

The most common problems that can occur when using high pressure cleaners are listed below:

  1. If there is a problem with the low pressure, loosen the garden hose and make sure that the tap water is under full pressure.
  2. If no pressure is applied, adjust the pressure relief screw and check the seals or springs for damage.
  3. In the case of pulsating pressure, the pump must be disassembled and the inlet components replaced or even cleaned.
  4. In case of repeated water hammering, make sure that the discharger is set to the correct pressure.
  5. If the pressure drops after a while, clean the nozzle with a needle.
  6. If a high-pressure cleaner does not clean the surface, switch to a high-pressure nozzle. However, check in the manual whether the surface can withstand a higher pressure.
  7. If you find a water leak on the pump, check the warranty and return or replace the unit.
  8. If water leaks from the garden hose, connect your appliance properly.
  9. If the spray leaks, replace the O-ring or turn the hose around and buy a new one.
  10. If oil leaks from the engine, the seals must be replaced under warranty.
  11. If you see water in the oil, your machine may be worn out or the pistons may be broken, so you should have a warranty repair carried out.
  12. If the chemical injector does not work, try inserting a black soap cap.
  13. In case of excessive noise, check and clean the machine or replace it under warranty.


Are these seals safe under pressure?

Although not much, it is not uncommon to wear protective clothing when working with a pressure washer, especially when using narrow angle nozzles. The ideal scenario would be to at least wear protective glasses, just in case. And if you want to make sure you’re safe, hard industrial boots would be very useful, because if you get hurt, it’s likely to have something to do with your legs and slippery, soapy surfaces. Don’t forget that these machines are really powerful and don’t underestimate them just because they spray water.

Which cleaning agent or detergent should be used with an electric pressure washer?

The safest thing to do is to check with the manufacturer of the model you are interested in to see if they have their own brand of cleaning products. That way you can be sure it works. However, as these detergents do not differ much from each other, they can easily be mixed. If you are not sure, test with less and see how the pressure washer reacts. Make sure you use the correct nozzle to apply the soap.

Can I have my electric pressure washer use hot water?

This is possible for some models, but not for others, so please refer to the manual. But although hot water is the logical choice for better cleaning, it will not give much better results. The use of hot water is only good in certain cases of really stubborn stains caused by grease or oil. The pressure generated by these machines is strong enough to withstand anything else, regardless of the water temperature.

What are the potential risks of pressure washers?

Pressure washers involve various potential risks. The high water pressure generated by these machines can cut your meat and cause serious injury. These machines can also allow water to penetrate under high pressure, which is extremely dangerous.

Some people think that water cannot be harmful, but it is important to remember that no matter what kind of chemical, when sprayed under high pressure, it can cause serious damage. Don’t forget to wear protective equipment such as long pants, helmets, hearing protection, goggles, gloves and boots when working with high-pressure cleaners.

In addition, excessive water pressure can damage the surface on which it is used. It is therefore very important to understand the color coding of the nozzles.

Is the pressure in the washing machine sufficient to damage the car’s paintwork?

Yes, of course detergents can damage car paintwork if not used properly. This pressure is very high and can easily damage the hard surface. Your car might even have a dent in it! So make sure the pressure washer is powerful enough to clean all surfaces, but make sure you get a pressure washer with an adjustable pressure.

Check the manual carefully. Also make sure you have the correct nozzle to maintain the correct pressure. Never make the mistake of being too close to the surface to be cleaned, as some surfaces can easily be damaged.

How should I store my washing machine?

Your high pressure washer is a powerful machine that needs to be stored with care. If it is an electrical appliance, make sure that it is completely disconnected from the mains and properly packaged. Keep it in a dry place to keep it functional.

What are the different types of pumps in electric washing machines?

Different companies use different types of pumps, and these pumps also differ from each other. There are three main categories: Axial cam pump, three-point pump and oscillating pump.

Axial cam pump

This type of pump can work well with high GPM and PSI. This is an intermediate pump that works better than the oscillating version because the pistons rotate around the PTO plate. This plate sweeps the piston while the piston sucks all the water from one side to the other.

The plate rotates around a shaft with the drive shaft directly connected. It has a lifespan of 500 to 800 hours and works perfectly with the 3500 PSI.

Plywood piston pump

The plywood piston pump can operate for thousands of hours and requires no maintenance. It can withstand high pressure and is used in most professional machines. It works like a car engine, with the pistons sucking and pushing water at every stroke.

It also has a lower speed so it runs cooler than engines and you can easily do most repairs and replacements. Most machines with a capacity of 3000 PSI work with this pump.

Oscillating pump

This pump is equipped with an oscillating plate connected directly to the shaft which pushes the piston forwards and backwards so that it can suck in and throw the water with great force. These pumps work perfectly with machines of 2500 PSI or less.

What chemicals can I use?

There are different types of soaps and detergents that you can use with your pressure washer, and they are all designed for different applications. You can get the details in our printed soap sheets.

For example, there is a separate detergent for washing the car and a completely different cleaner for cleaning the driveway.

You will find disinfectants that kill most bacteria quickly, detergents that remove dirt and disinfectants that kill all kinds of microorganisms.

– You can buy these chemicals separately, and some machine manufacturers sell them -with the product as an accessory. The manufacturers of these chemicals label them based on their recommended surface and use.
– You can use vinegar to clean worktops or windows. It can also be used to polish surfaces from bronze residue to brass door handles.
– Citric acid is most suitable for concrete paths and wooden surfaces.
– Oxalic acid is very suitable for removing rust on various surfaces.
– Bleach is very suitable as a disinfectant or as an aggressive disinfectant because it is made of sodium hypochlorite and sodium hydroxide. Use them carefully.
– Sodium hypochlorite is also a stain remover and a powerful disinfectant.
– Sodium hydroxide, also known as a caustic substance, can dissolve fats and grease and is normally used for steel and glass.
– Ammonia is a common cleaner for stainless steel and glass.
– Potassium hydroxide is used for the production of liquid soaps for cleaning purposes.

What should the weight of the washing machine be?

An average capacity washing machine can weigh between 25 and 100 pounds. The weight of the machine depends entirely on the load capacity and the engine mounted on it. Most household cars weigh around £25 to £50, while commercial units are heavy – they exceed the £50 limit.

How much water is used for electric pressure wsher?

There is a common misconception that a normal garden hose uses less water than a high-pressure cleaner, but the reverse is true. The high pressure washer uses about 2 litres of water per minute, while the garden hose uses 20 litres! The use of high-pressure cleaners saves water.

The amount of water needed to carry out the work depends on the type of work being carried out. For small jobs such as washing cars, for example, a light washing machine is required with a water pressure between 1400 and 1750 PSI and a flow rate between 1.4 and 1.6 GPM.

To clean the road, you need a medium pressure cleaner with a PSI between 2300 and 2500 and a GPM between 2.2 and 2.3. It may seem like a lot, but light machines use 685 times less water than your garden hose.


There, it’s done. Everything you need to know about the most powerful electric washing machines. They deliver a lot, and you shouldn’t bother them. Don’t confuse them with toys, but don’t hesitate to experiment with them and make sure they are versatile so you can use them yourself. We believe you should arm yourself with the knowledge we have provided in this guide and these -feedbacks for electric washing machines, to really get a dream washing machine for your farm.

Because the more you know, the sooner you can wash all those annoying stains from your driveway and patio furniture. The feeling of using a powerful electric pressure washer is invaluable, fun and interactive.
