Buy a high-pressure cleaner - these are the criteria that count

In order to be sure that you are buying a good, high-quality device for loosening dirt particles and cleaning dirty surfaces and objects, it is important to pay attention to a few criteria.

Difference between high pressure cleaners and steam jets

Many people ask themselves what the difference is between a high pressure cleaner and a steam jet. Although both devices are operated with water, there are different modes of operation and also different areas of application in which the devices are used.

High pressure cleaner: The high-pressure cleaner is mainly used outside. In this context, it is used to clean sidewalks, roofs or pipes, vehicles, etc., among other things. Due to the large selection, cleaning can be carried out with cold, warm or hot water as required.

Steam jet: In contrast to the high-pressure cleaner, the steam jet is mainly used indoors. The device generates hot water vapor and is mainly used for cleaning surfaces down to the pores.

Such a device does not leave any water residue, as the water is heated to over 100 degrees and is therefore cleaned with steam and not with liquid water.

Applications of the high pressure cleaner

The area of ​​application of a high-pressure cleaner is diverse. Although such a model is primarily known for being able to remove dirt from front gardens, terraces or even floor coverings on balconies effectively and reliably, there are no limits to the area of ​​application of such a device.

Among other things, the high-pressure cleaner can be used wherever dirt has to be reliably removed from surfaces. This can not only apply to floor coverings, but also to

  • Vehicles
  • Tools
  • House walls
  • Facades

be the case.

The only important thing is to ensure that the object to be cleaned can withstand the pressure with which the water comes out of the nozzle of the device and does not fall over.

How does a pressure washer work?

The way a pressure washer works is not difficult or complicated. Inside the device there is a powerful high pressure pump, whereby the performance of the individual pumps can vary from model to model. Depending on the model, this pump is supplied via a water connection or draws the water from the integrated water tank.

The water is then pressurized by a reciprocating piston and pushed out of the device via an outlet valve. You can then use the hose and the handle to direct the water onto the surface or onto the device or object that needs to be freed of dirt, dust and residues.

How and for what do you use a pressure washer?

Depending on the operating mode, the high-pressure cleaner is plugged into the socket or simply operated by a battery or operated with petrol and switched on. Then the device starts to work immediately and after a few moments the water flows out of the nozzle, so that you can effectively declare war on dust, dirt, deposits and other residues.

High pressure cleaners - what should you watch out for?

Anyone who decides to buy and use a pressure washer must bear in mind that such a device works with a lot of pressure. For this reason it is important to have a firm and secure grip over the hose and the device. Otherwise you run the risk of the hose being thrown back and forth by the pressure and you might even injure yourself on it.

The different versions

There is not only one version of the high-pressure cleaner on the market, but among other things, a distinction is made between different operating modes in the various models. Among other things, there are:

  • Petrol pressure washer
  • Battery pressure washer
  • High pressure cleaner with mains connection
  • Mobile pressure washer
  • Mini pressure washer
  • High-pressure cleaners as surface cleaners

The petrol pressure washer: This variant runs on petrol and is characterized by its particularly high performance. Petrol high-pressure cleaners can be used very flexibly outdoors because they can be operated independently of a socket.

Battery pressure washer: Not only the gasoline high-pressure cleaner can be used flexibly and independent of location - the cordless high-pressure cleaner can also be used at different locations as required due to its nature and the fact that it can be operated via an integrated battery.

High pressure cleaner with mains connection: Another operating mode that is used in the frame of the high-pressure cleaner is the connection to the central power supply via a power cord and a power plug.

In this case, however, one is dependent on the length of the respective power cable and limited in terms of flexibility during handling. If required, such a model can of course also be connected to an extension cable or a cable drum to increase the range of motion.

Mobile pressure washer: Basically, a mobile high-pressure cleaner is simply a device that can be used flexibly and anywhere. This is the case if the device is a model that runs on either petrol or an integrated battery.

Small pressure washer: A mini high-pressure cleaner is a model that usually does not have a lot of bar and watts and is often only equipped with a small water tank. If you are looking for a device with which only very small surfaces or objects are to be cleaned occasionally, a small, compact device is the best choice.

High pressure cleaner as a surface cleaner: A high-pressure cleaner as a surface cleaner is characterized by having a very special shape and not being operated with a gun. It can be placed directly on the surface to be cleaned using a vacuum cleaner-like attachment.

This not only ensures that the water jet is pressed directly onto the surface to be cleaned, but at the same time prevents the water from splashing on all sides. If you already know that you only want to use the high-pressure cleaner to clean different surfaces, you should therefore decide to buy the specially shaped high-pressure cleaner.

Pressure washer - how much bar do you need?

The commercially available models differ not only in the operating mode, but also in the pressure with which the water is pressed out of the device.

How much pressure you need to clean the surfaces or objects always depends on how stubborn the dirt or how big and robust the object to be cleaned is.

For example, a low pressure of between 150 and 180 bar is perfectly adequate for cleaning a bicycle. For a floor covering on the terrace or balcony, you can choose a device with a higher pressure between 200 or 300 bar.

With some devices, the pressure can be adjusted as desired, so that bicycles and other objects can be cleaned with a low pressure and surfaces or facades can be cleaned with a high pressure.

As a rule, a distinction is made between models that work with the following pressure:

  • 150 bar
  • 160 bar
  • 180 bar
  • 200 bar
  • 250 bar
  • 300 bar
  • 500 bar (particularly powerful devices, which, however, are usually not used in the private, but more in the commercial sector)

The water for the high pressure cleaner

A high-pressure cleaner is so popular for this reason, because it skilfully combines pressure with water and thus ensures that surfaces or objects can be cleaned well and reliably.

Regarding the water that is used in this context, a distinction is made between the following temperatures in the various models:

  • Pressure washer with cold water
  • Pressure washer with hot water
  • Pressure washer with hot water

It is important to differentiate between the temperature of the water, as hot water uses much more electricity than hot water.

High pressure cleaner with cold water: High-pressure cleaners that clean with cold water are usually offered cheaper than high-pressure cleaners that work with warm or hot water. They are effective when the dirt to be removed does not adhere strongly to the surfaces to be cleaned. For example, when the terrace has just been muddy, or to clean very dusty objects.

High pressure cleaner with hot water: A high-pressure cleaner that works with warm water is a commercially available model that is usually used in the private sector. If you decide to buy a conventional high-pressure cleaner, you will receive a model that removes dirt and dust with warm water.

High pressure cleaner hot water: As already mentioned, a high-pressure cleaner needs a lot more electricity to heat the water it needs for use to a particularly hot temperature. For this reason, devices of this type are also increasingly being used in the commercial sector.

In this case, the water is heated to up to 90 degrees, so that even particularly stubborn dirt and residues can be removed effectively and reliably.

Distilled water VS tap water

You don't necessarily need distilled water, but it has many advantages. Distilled water is desalinated and almost free of other dissolved ingredients - unlike tap water.

Because the distilled water does not contain any ingredients, it absorbs dirt particles better. In addition, the demineralized water does not contain any lime.

When cleaning with distilled water, you generally benefit from these advantages:

  • no limescale deposits
  • less streaking (e.g. on car windows)
  • less detergent needed
  • Dirt doesn't build up again that quickly

However, distilled water is not all about benefits. There are materials that shouldn't be used exclusively. Distilled water has a different pH than tap water. It's slightly acidic. If it is used exclusively, it can attack metal parts or rubber seals.

Can you save money with tap water?

Conditionally. Apart from the materials, for which one should not only use distilled water anyway, the savings with tap water are hardly noticeable. Because dirt accumulates more quickly, the high-pressure cleaner also has to be used more often. That in turn costs electricity and water again.

How do you connect a pressure washer?

Regardless of the way in which the high-pressure cleaner is operated - in order to be able to fully pursue its functionality, it usually has to be connected to a water pipe. This is the only way he can get the water he needs to clean the object, device or floor.

Only small battery models often do without a direct connection and are equipped with tanks that can be filled.

In principle, it does not matter which water pipe the high-pressure cleaner is connected to, as the connection of the individual models is often compatible with all conventional water pipes and taps. You can connect the high-pressure cleaner to taps in the house, in the garden or on the terrace, among other things.

The manufacturers provide precise information on the connection in their product description so that the thread actually fits at the end. If you still grab it wrong, you can also buy adapters. In some places they are also supplied directly.

Anyone who opts for a high-pressure cleaner with mains operation must also ensure that a socket is available near the place of use. Basically, it is sufficient to plug the high-pressure cleaner into a normal socket, since a conventional 230 volt cable is completely sufficient for most models on the market.

Pressure washer with a water tank

Not all models have to be connected to a water pipe, as some cleaners also have an integrated water tank that can be filled with a certain number of liters and then used on the move.

In this case, you should always consider in which area you want to use the high-pressure cleaner in order to decide on a correspondingly large water tank. Otherwise you run the risk of refilling the tank again and again and consequently having to interrupt your work.

The size of the water tank of the individual models can vary from manufacturer to manufacturer. Among other things, however, models with the following sizes can be found on the market:

  • 4 liters (for small models)
  • 15 liters
  • 20 liters

Pressure washer with suction function

If you don't want to be tied to a tank or a tap in order to be able to operate the high-pressure cleaner, you should opt for a high-pressure cleaner with a suction function.

Such a device is characterized by the fact that it can use any water source. This means that such a model could also be operated with the water of a river or a lake.

The performance of the pressure washer

The performance of the pump inside the model differs from high-pressure cleaner to high-pressure cleaner.

Among other things, models with the following services can be found on the market

  • 300 watts
  • 400 watts
  • 100 watts
  • 200 watts

Basically, a device with more bar also has more watts and these two sizes are therefore in an important relationship to one another when buying such a device. The more bar and watt, the more powerful the device.

The nozzles of the pressure washer

If you want to declare war on particularly stubborn dirt, you can support the high-pressure cleaner with an appropriate nozzle in order to be able to look forward to even better results, but above all to a clearly uncomplicated handling.

Dirt blaster for high pressure cleaners - rotary nozzle: This nozzle is particularly suitable for very firmly adhering dirt. Due to its nature, it ensures that a concentrated point jet is shot at a very high speed onto the surface, which has to be cleaned and freed from dirt.

This not only removes dirt much better, it also protects walls, panes and the users of the device themselves from the water.

Foam nozzles: Foam nozzles are special nozzles that are mainly used in combination with cleaning agents. With their properties, they ensure that a particularly large amount of foam is formed and that this not only adheres better, but also longer.

Swiveling nozzles: Another model of the nozzles that can be attached to a high-pressure cleaner in order to be able to clean surfaces better are swiveling nozzles. These are mainly used when you want to thoroughly clean hard-to-reach areas.

This means that these nozzles are used primarily for washing cars or for rinsing out garbage cans. The jet of water can be directed forwards, to the side, upwards and downwards as you like thanks to the nozzle that can be swiveled 360 degrees.

Pressure washer with a brush

Not only can you choose between different nozzles in order to better declare war on dirt, but you can also use a suitable brush to clean objects and house walls or floors much better and more reliably.

In this context, a wheel rim washing brush is particularly popular as it makes cleaning hard-to-reach places and even small spaces much easier.

The high-pressure cleaner and the right cleaning agent

When it comes to cleaning agents for high-pressure cleaners, a distinction must be made as to whether you are looking for an agent with which the high-pressure cleaner should better clean surfaces or objects or whether you want an agent with which the high-pressure cleaner can be cleaned itself.

In order to be able to guarantee the correct functioning of the device, it is important to clean it at regular intervals to ensure that it is free of dust, dirt and other residues.

With the cleaning agent, care must always be taken that the objects and surfaces that are to be cleaned with it not only withstand the water pressure itself, but also the ingredients of the cleaning agent.

If, for example, an aggressive agent is used for sensitive surfaces, this, in combination with high water pressure, can lead to damage to the surface of the object or the area.

Among other things, you can buy the following cleaning agents for this purpose

  • Vinegar cleaner
  • Green soap
  • All-purpose cleaner
  • Plastic cleaner
  • Wood cleaner
  • Car cleaner
  • Stone cleaner

For cleaning the device itself, you can also find a special cleaning agent for high-pressure cleaners.

The hose for high pressure cleaners

Especially devices that are not flexible in their usage radius should always be equipped with a long hose in order to be able to ensure that they have a little more freedom of movement and thus to be able to use the device flexibly to a limited extent.

High-pressure cleaners in and of themselves already have a hose that can be exchanged for new hoses at will. The hoses, which always have to be robust and stable, are available in different lengths. Among other things, the following lengths are available to buy

  • 6 meters
  • 10 meters
  • 15 meters
  • 20 metres

Accessories for the pressure washer

When you buy a high-pressure cleaner, you usually get the basic equipment with which the device can be put into operation directly. However, some manufacturers offer buyers a very large scope of delivery or the opportunity to buy additional accessories for the device.

This includes, for example, hoses, adapters or replacement batteries.
