Factors to Consider When Buying the Best Electric Pressure Washer

Home » Home & Kitchen » Factors to Consider When Buying the Best Electric Pressure Washer

Choosing the best electric pressure washer for home use is not easy. If you are thinking of buying one, we will give you the information you need to get the best.

Pressure washers are tools that, from a connection to a water source, add pressure to it.

Depending on the characteristics of the washer machine and the configuration, the washer is capable of delivering pressures of up to 50 times more than a hose. 

Equipped with the correct accessories, they are the best for cleaning surfaces, vehicles, cleaning in height, in pipes, etc.

The high pressure that the electric pressure washers provide translates into a stronger impact on the surface to be cleaned. This makes removal of dirt easy.

There are accessories for pressure washers that help clean different types of surfaces, from cars to patios or walls. In many cases, the compatibility depends on each brand, so it is important to investigate the pre-purchase options.

How does an Electric Pressure Washer Work

The pressure washers have a motor, which can be electric or run on fuels, which adds pressure to water.

When you enable the water outlet by means of a trigger, the water circulates from the high-pressure hose to the gun whose nozzle at its end determines the size of the outlet jet, and therefore the impact that the water will have on hitting the surface to be cleaned.

What you should keep in mind to choose your power washer

Less experienced users run the risk of looking only at power bars when looking for the best electric pressure washer in the market. The reality is that not having more pressure will be a better team.

Remember to always look for the balance between pressure and flow.

The flow rate is the liters of water per minute that the machine is capable of releasing. Therefore, a large number of power bars does not work if the flow rate is then limited

We are talking about looking for the best performance of the pressure washer, and it is a good performance that saves water and time (which ultimately translates into saving money ).

Having this clear, the next point is to bet on its useful life, and a fundamental factor is…

Pump or motor

Before buying a pressure washer it is important to know what material the pump is made of, which is the engine that generates the pressure.

We found 3 main materials with which the pumps of the pressure washers are manufactured:

  • Brass: used in professional pressure washers to work at the industrial level.
  • Plastic (not recommended): Plastic considerably increases the risk of leaks and short service life.
  • Aluminum: the best option for household or home use washers and semi-professional use.

Bet on the aluminum pump to guarantee the best value for money and long service life.

We continue with the different elements that make up the pressure washers so that you know all the advantages of these pressure cleaning machines.

The pressure (in bars)

If we talk about removing dirt effectively, pressure washers are the best tools. Water combined with air pressure can combat the most embedded dirt saving time and effort.

The bars are the units to measure the pressure, we must make reference as to what’s going to use. The higher the number of bars, the more pressure and power the pressure washer will have.

Here are some references:

Light use – 100 bars

  • Outdoor furniture
  • Garden tools
  • Motorcycle
  • bikes
  • Trash bins

Medium use – 110 to 130 bars

  • Car cleaning
  • Heavy tools
  • Small pools and hot tubs
  • Small boats

Intense use – 130 bars or more

  • Bricks
  • Roads
  • Patios
  • Facades

If we only want to use it to clean the car, bicycles, some furniture or small surfaces, there are cheap and compact models with enough bars and power for it.

To clean the car it is not recommended to go to maximum power, as it could damage the paint of the car due to overpressure. If you buy a high-pressure washer it is best to make sure that it can be adjusted to adapt it to any task.

If you want to remove embedded dirt from larger surfaces, you must increase the number of bars. The average in the standard pressure washers ranges between 110 and 180 bars.

If we are thinking of cleaning the inside of the pool, large vehicles or wider surfaces it is best to buy a powerful one that reaches 160 bars.

Finally, if you are looking for an industrial pressure washer for professional use, there are good offers of petrol washers of more than 200 bars perfect for heavy machinery, 4 × 4 vehicles, trucks or caravans cleaning.

Water flow (in liters per hour)

The flow of water is another point to consider before buying a power washer. The flow capacity depends on the liters of water per hour.

If we want greater water output capacity to enhance cleaning we must choose a model of good flow and pressure. 

The average flow rate of a good pressure washer is 400 liters per hour.

How to choose a pressure washer

No doubt the pressure washers are some of the best cleaning equipment in terms of efficiency and effectiveness, there are several factors to consider when selecting a pressure washer.

The pressure cleaner you buy depends mainly on the work to be performed or the time of use, between other factors.

I will show you the factors that you should take into account to know how to choose the most appropriate pressure washer.

Electric Hydro Washer or Gasoline Hydro Washer

Electric pressure washers are more common or popular due to their high demand in domestic or residential tasks.

 This type of pressure washer is ideal for use in places where there is an electrical connection.

There are several models, which have different lengths in the cable, which is a factor that must be considered.

Also, the power supply that the equipment requires is also an important factor. There are models that work with 1 to 3 phases and different types of voltages.

Gasoline pressure washers work independently; they do not depend on electricity. They have greater freedom of movement. 

Most have more power so they are recommended for high demand jobs. 

However, this type of pressure washer is recommended for use in outdoor and open spaces, due to the carbon monoxide emissions they generate.

Gasoline pressure washers are physically larger than electric ones, so they require a little more effort to move from one place to another.

Hot water or cold water pressure washers

This factor depends directly on the use that is going to be put.

Hot water pressure washers are more recommended to remove dirt from hard residues, oils, and fats embedded in the surfaces.

High temperature water is more effective to break them down. Also, hot water reduces working time and increases the efficiency of chemicals.

Cold water pressure washers are used for less laborious applications.

A cold water pressure washer with great pressure helps to remove dirt effectively but in a long time; the washer teams only takes the water directly from the supply and throw it under pressure.

Pressure of the pressure washer

The pressure is expressed in pounds-force per square inch PSI (pounds-force per square inch).

Depending on the work to be performed with the pressure washer, go for a machine with the right pressure.

Based on our experience, we give you a pressure index that can be used in different cleaning environments:

  • Vehicles 1,100 PSI to 2,000 PSI
  • Industry 2,000 PSI to 2,500 PSI
  • Trucks, trailers, tractors, chassis 2,000 PSI to 2,500 PSI
  • Stables 2,500 PSI to 3,000 PSI
  • Hard, extensive surfaces, patios 3,000 PSI to 3,600 PSI

Flow of a pressure washer

The flow rate is indicated in liters per minute (lpm) or gallons per minute (gpm). 

As far as the pressure washers are concerned, the higher the flow rate, the higher the cleaning speed. 

Once the proper pressure for cleaning is determined, the only way to speed up the process is to increase the speed of the water. 

Remember that the water flow cannot be increased beyond its capacity.

Necessary care and Caution

Like any tool, there are more appropriate ways to use the best electric pressure washer and there are potential risks that can be avoided by following best practices.

First of all, pressure washers are equipment that operate water at very high pressures. 

Never point the outlet of the pressure washer at a person or animal because it can cause serious damage. 

You should also keep in mind that it is possible that there are elements (such as stones) that are loose or detach from the impact of water that can also cause harm to a person. 

Never allow children to operate or play with the power washer.

You should never use a pressure washer on a ladder , the propulsion generated by it can cause you to fall. You should always operate it from the floor, and in the cases it deserves, you must use extensions.

In the case of those that run on electricity, keep in mind that water and current are not a good combination, and in that sense, operate the electrical connections properly when you are using the pressure washer. On the other hand, in the case of those that run on fuel, remember to use them in ventilated places.

Factors to Consider When Buying the Best Electric Pressure Washer

To avoid damaging surfaces, remember to moderate the impact force. Always start off the surface and avoid impacting perpendicular to the surface. From there, adjust the nozzle and adjust the distance as you see fit. Remember that there are surfaces that can be damaged by the constant impact of highly pressurized water, such as wood, plaster or some ceramic tiles.

Now that you have this data, we believe that it will be easier for you to choose the ideal pressure washer according to your needs, we remind you that part of the proper functioning of a device beyond choosing a good equipment is to maintain it and have it in optimal conditions for its use.
