How to choose the best pressure washers?

Selecting a pressure washer can be a difficult task if you do not have knowledge about its different types and uses. For this reason, thinking of facilitating your search, we present the following guide to buying the best pressure washer, with which you will be able to know the most important characteristics that you must take into account.

Shopping guide


When making a comparison of pressure washers, it is possible to distinguish between two different types depending on their engine, since some are electric and others run on gasoline. Those with an electric motor are suitable for occasional domestic use, since they must be connected to the current for their operation. However, they are usually quieter.

Gasoline engine pressure washers are designed for professional use, since they have higher output power, which translates into a stronger and wider flow. Also, these are suitable for outdoor work and have the capacity to work with hot water.

It is important to note that most pressure washers, whether gasoline or electric, offer light weight and small size. In addition, they can incorporate compartments that allow you to store your accessories with greater comfort and order. For this reason, if you need a model for home use, these portable computers that usually provide practicality are recommended.


Some of the characteristics that can indicate how much a pressure washer costs are the level of water pressure and power. In the case of these machines, the pressure is measured in bars and refers to the water’s expulsion capacity, so the higher its pressure, the more effective it will be for cleaning.

In this sense, you can find pressure washers that offer between 110 and 213 bars of pressure, as well as a power of 1,300 W to 2,500 W, depending on their motor. This could generate a variable flow of water that can be around 500 liters per hour, so you must consider consumption according to the needs of the work, so that you do not waste water. In addition, a good performance could be between 20 m2 and 25 m2 per hour.


Pressure washers are especially useful tools for cleaning multiple surfaces and objects. However, we can find some models specifically indicated for those cases in which the dirt is strongly adhered to the different surfaces or is located in areas that are difficult to access, whether they are corners and small compartments; in this case, the use of small nozzles is recommended.

Other pressure washers can make it easier for you to clean patios, walls and floors, whether they are made of bricks, cement, tiles, among other materials. Normally these are the ones that can expel a stronger flow. Also, there are domestic models designed to clean garden and construction tools, garden furniture, garage doors, grills, bicycles, motorcycles and cars. Similarly, some gadgets can be useful in plumbing jobs, such as unclogging pipes and tubes.


It is important to mention that the level of pressure and the effectiveness of the work also depend on the different types of equipment and accessories that the pressure washer has, since each one offers you a different flow of water for different tasks.

Among the main components of a pressure washer machine are the guns, lances and nozzles. Guns are generally made to withstand the high pressure of the water coming out of them. For their part, the nozzles offer the possibility of controlling the water and the detergent in different ways, either with the use of a rotating or fixed jet, but there are also some specifically indicated for dispensing detergent.

Similarly, the hoses can offer different lengths, to facilitate freedom of movement according to the work you do. In this sense, you can find them between 3 and 6 m in length. In addition, some models include a swivel function that prevents them from twisting, so that their use is easier and faster.

On the other hand, the water filter is another fundamental component in this type of tool, because it is capable of avoiding blockages in the pump and in the pipes. Likewise, it is recommended that the model of your choice incorporate a detergent tank, which in some cases could be removable to facilitate its use and cleaning.

If you are looking for a good and cheap pressure washer, you should also make sure that it includes at least one insurance against accidental start-up. In addition, part connectors need to be considered, as this way you can ensure quick and easy change of nozzles and their accessories.

Remember that the maintenance and periodic cleaning of all the components are also a fundamental aspect to guarantee the proper functioning of the device, so it is recommended that you make notes with the dates when you clean them.

Frequently asked questions

Q1: What type of oil does a pressure washer use?

The appropriate oil for each pressure washer, according to the opinion of some experts, should be selected based on the type of work to be carried out and the climatic conditions. In this sense, a machine for domestic or occasional use uses a light 4-stroke oil, like the one generally used in motorcycles.

In the case of machines for professional use, where the work to be carried out is more demanding or for a prolonged period of time, the appropriate oil must be one with higher viscosity, which also works in variable or very hot climatic conditions.

Q2: How many bars should a pressure washer have?

Bars refer to the pressure measurement that indicates the level of efficiency of a pressure washer, so it is important to take into account the number of bars offered depending on the work to be carried out.

In this sense, for occasional use on furniture, bicycles and balconies, it should be between 100 and 110 bars. For moderate use on walls, floors and cars, it is recommended that it offers between 110 and 120 bars. However, you need between 120 and 160 bars for frequent or intensive use on roofs, facades, swimming pools and exterior floors.

Q3: Which is the best pressure washer, Nilfisk or Kärcher?

A good option to decide between these two manufacturers is to take into account your needs and the type of use you will give the machine. Therefore, it is important to know that both the Nilfisk and Kärcher brands have good quality products.

In this sense, you should consider whether the pressure washer will be for occasional or professional use, since based on that you will be able to select a model that has the appropriate number of bars, power, flow rate and accessories.

Q4: How to disassemble a Kärcher pressure washer?

Once you finish the job and you have to disassemble the pressure washer, the first thing to do is turn it off and disconnect it from the electrical current; this way you will avoid accidents. Afterwards, close the faucet and eliminate the remaining water inside the pump and hoses, so you can prevent corrosion of its parts.

The next step will be to disconnect the gun, the lance, the work hose and the one that supplies the water from the pipe at both ends. To finish, you must place each piece in its storage place.

Q5: What detergent to use for a pressure washer?

The right detergent may depend on the type of object or surface you want to clean. In this sense, you can find a wide variety with detergents specifically indicated for use on wood, plastic, stone, car, among others.

However, you can also count on a universal detergent, which is suitable for occasional, domestic use, with hot and cold water. Also, as its name indicates, you can use it for different types of objects, such as furniture, cars, facades, tools, among others. This is thanks to the fact that its components do not cause any damage to surfaces. However, it may not be as effective as a detergent specifically made for one type of material.

How to use a pressure washer

Starting up a pressure washer is usually a simple process, for which we only need to follow a few steps. However, if you are not familiar with that process, here we will explain in detail how to do it efficiently.

Put the detergent

Most of the models available on the market offer the possibility of using detergent to obtain better results during cleaning. In this sense, you must start by identifying the corresponding tank in your pressure washer and then fill it with the appropriate type and quantity.

It is important to highlight that it is good to use detergents made specifically for pressure washers, since they increase their efficiency and do not damage the parts of the equipment. Also, you must take into account the object or surface to be cleaned, as well as its dimensions. This way you will avoid wasting water and detergent. In addition, it will help you take care of the environment.

Select the temperature

High pressure washers generally work with a cold water system. However, today many models have incorporated a support system for hot water inlet. In this way, they allow you to adjust the temperature between 40º and 60º C.

This is because hot water offers a better level of cleaning, due to its degreasing power. However, it is not advisable to use excessively high temperatures, as it could damage some parts of the machine and even some materials of the objects you decide to clean.

dispense the water

Before dispensing the water, you must connect the hose at both ends, one to the tap and the other to the machine. In some cases, the end that is attached to the appliance has a filter between the hose and the pressure washer. After making the connection correctly, you must select the appropriate nozzle according to the work to be done. It is necessary that it be connected to the gun before opening the tap that will let the water pass.

Also, before starting cleaning it is important to check that the pump has a constant flow and no air. You get this by opening the tap and pulling the trigger until you get it. In this way, you can guarantee a correct cleaning. In addition, you extend the useful life of the device, since you prevent the parts from being damaged during use.

Starting the engine

Once the previous steps have been carried out, it is time to start the pressure washer. In this sense, before activating the ignition switch, you must connect it to the network if it has an electric motor and, if it has a gasoline engine, it is recommended that you make sure that it has enough fuel and oil to work.

The next step has to do with regulating the water outlet pressure according to the type of work you are going to do. This procedure is important, since if you apply too much pressure on a surface that is not very resistant, you could cause damage to it.

Now, it only remains to bring the nozzle closer to the surface and remove the adhering dirt. However, you should also consider the flow of the water while it is in use, since some models can expel more water than others, which can have consequences when the water bill arrives. In addition, it is not very respectful with the environment. For this reason, it is important that you control the amount of water you consume while using a pressure washer.
