A pressure cleaner is a cleaning instrument that cleans almost anything we have outside of our home. They clean so easily and aggressively that they are even fun to use.
Learn how to use a pressure cleaner safely and efficiently.
As we have said previously, pressure washers are very useful for cleaning almost anything, from terrace furniture, facades, windows, concrete floors or outdoor tiles, vehicles and endless cleaning activities.
Depending on the type of work and its periodicity, we will need different models, for most domestic jobs a pressure washer will suffice, also known as pressure cleaners, which has a pressure of 115 bar, but for the most complicated tasks we will need machines that have at least 180 bar pressure. The pressure at which the water comes out could be a fact that must be taken into consideration when buying a pressure washer, but the second factor is that the flow of water that it expels. A pressure cleaner is useless if it does not expel enough water afterwards to remove the stubborn dirt.
We can also have doubts between buying one or renting it. Here again it depends on the periodicity of use, if it is for a specific job and you are one of those who go to the car wash to wash the car, do not hesitate and rent one, however if you are going to use them with a certain frequency you need to buy one and owning it to use it whenever you think it is necessary, it will be more profitable for you.
Types of pressure cleaners and how they work.
Pressure cleaners or water washers regardless of whether they have a combustion engine or an electric motor, have a pump that is responsible for pressurizing the water that comes from the garden hose to which you have it connected to reaching figures of from 100 to 200 bar or even more depending on the model you are using. The higher the pressure of the pressure washer and its water flow, the descaling tasks will be more affordable to perform, taking less time and effort. Both models, both with a combustion engine or electric, need a constant and stable supply of water.
Electric pressure cleaners with a pressure of between 130 and 150 bar with an approximate water flow between 360 and 450 liters per hour will be the best option for light cleaning tasks like cleaning cars, motorcycles and garden furniture. If we need a little more power we can go to the next level where we find ourselves with pressure washers with pressures between 160 and 200 bar with water flow rates between 450 and 600 liters per hour, these pressure washers are the most versatile and will be of great help. for all types of jobs even those in which dirt is really embedded, such as rough pavements in gardens, trucks and agricultural machinery such as tractors, cleaning large areas of floors with paving stones, curbs, etc.
As for pressure washers with combustion engines, they are designed for very high working pressures and deliver a very large volume of water. Its use of course is intended for industrial work and places where there is no nearby electricity supply. A disadvantage is that they are larger, heavier and difficult to transport, not to mention the consumption of gasoline and that unlike the electric ones that require minimal maintenance, the combustion engine ones require more maintenance.
How to start a pressure cleaner?
When we put a high pressure cleaner into operation, regardless of whether it is electric or with a combustion engine, we have to pay special attention to the fact that the water supply supplies a sufficient flow to the characteristics of the pressure washer. If we have doubts about whether our water point offers the necessary flow we can always perform a simple calculation using the typical 12-liter plastic pot, if we need less than 60 seconds to fill a water pot it means that our tap will provide no less 900 liters of water per hour, more than enough for a domestic pressure washer.
The most appropriate hoses to connect a pressure washer are kink-proof hoses, “non-twisting” in the manufacturer’s specifications, with an internal passage not less than 3/4 and if possible equipped with quick connectors at both ends to connect to the tap and our pressure washer.
We have to pay special attention to the water with which our pressure washer will work, if we have doubts as to whether it may contain residues we must install a filter within the hose to avoid very serious damage to the pressurization pump. These filters for pressure washers are very economical and can avoid problems of high repair cost, having the ability to work with complete peace of mind.

Tips for starting the pressure cleaner.
- Before putting our pressure washer into operation, it is mandatory that the water passes from the irrigation hose, completely fills the pressurization pump and leaves through the nozzle of the gun. Today most pressure cleaners have the “Total Stop” system, which prevents the machine from being constantly running when the gun trigger is not pressed. This is achieved by means of a valve in the pressurization pump that when reaching a certain pressure causes the electric motor to stop. If the pump is not fully charged with water, there is air inside it and it often happens that the operation of the pump is erratic and gives violent blows that can cause damage. To avoid this, we must proceed as follows:
- Tighten and tighten all connections between the pressure washer and the tap and check that air cannot enter the water line.
- Open the garden tap where we have connected the hose and the pressure washer and without starting the engine but with the trigger of the gun activated, let the water run for at least one minute.
- We will proceed to the start-up of the pressure cleaner, paying attention with its combustion engines to let it warm before starting to work with it.
- Adjust the nozzle of the lance looking for the type of spray that best suits each job, you can choose between a wide fan to a direct jet that is the most aggressive. Different models of pressure washers have interchangeable lances with turbo nozzles for a more thorough cleaning.
It is advisable to carry out tests in inconspicuous places to verify that an excess of pressure or the way of spraying does not damage the materials to be cleaned. This is important on delicate surfaces such as wood, plastics and especially when cleaning vehicles, since excess pressure can tear the paint off.
We should never clean a surface with a direct jet of water since in this way the dirt will be projected in all directions, it is best to acquire an angle of attack of approximately 45 ° to remove the dirt and in turn move it off the surface, remaining totally clean.
When cleaning facades of homes, we’ve got to place special caution and common sense within the area of the windows, performing at minimum pressure since the glass could break with high pressure.
