What is a cordless pressure washer?

What is a cordless pressure washer?

Cordless pressure washers are more compact, mobile and somewhat less powerful versions of ordinary high-pressure cleaners. They are used to remove dirt from surfaces with a strong water jet.

Many cordless pressure washers work with a water pressure of 5 to 20 bar, which would be more accurate to call them “low-pressure cleaners”. By comparison, normal pressure washers often reach a water pressure of up to 100 bar.

How does a cordless pressure washer work?

How does a cordless pressure washer work?

All cordless pressure washers work in the same way. The battery is responsible for supplying power to a pump. The pump sucks in the water and transports it via two suction valves to one piston each. The pistons are mounted on a movable disc – the so-called swash plate. This is set into a forward-backward motion by the water pressure. This presses the water at high speed through pressure valves towards the nozzle – the water flows outwards at high pressure.

In the process, the pistons are alternately pushed by the swash plate and then returned to their original position by a return spring. Depending on the engine speed, this process is repeated about 1,400 to 2,800 times per minute. The motor speed determines the pressure at which the battery-powered high-pressure cleaner delivers the water.

For a continuous water jet, it is essential to alternately push and pull the pistons. If the pressure washer had only one piston, the water would flow out of the nozzle intermittently.
What types of cordless pressure washers are there?

What types of cordless pressure washers are there?

Cordless pressure washers can be divided into models with an integrated water tank and those with a hose connection. This results in individual advantages and disadvantages, which we would like to discuss in the following section.

In contrast to conventional pressure washers, there are no cold and hot water models in the battery-operated high-pressure cleaner range. Only cold water can be used.

Cordless pressure washers with water tank

Cordless pressure washers with water tank

There are cordless pressure washers that draw water from their own water tank. A permanent connection to a water hose is not necessary, which results in flexible application possibilities. The biggest disadvantage is that a full water tank makes the cleaners several kilograms heavier. It should also be mentioned that the usage time is not only limited by the charge level of the battery, but also by the fill level of the water tank.

Positive
  • No permanent connection to a water hose required
  • Flexible application possibilities
Negatives
  • High weight with full water tank
  • Useful life limited not only by the battery but also by the water tank

Cordless pressure washer with hose connection

Cordless pressure washer with hose connection

Battery-powered pressure washers with hose connection draw their water from an external source. This makes them lightweight and easy to transport. The water supply is permanently ensured via a hose, which is why the usage time of these devices is limited solely by the battery. The only disadvantage is that the radius of movement is limited by the water hose.

Positive
  • Low weight due to external water supply
  • Useful life limited exclusively by the battery
Negatives
  • Limited radius of movement

What are cordless pressure washers suitable for?

Battery-powered pressure washers are versatile cleaning devices that are suitable for much more than cleaning facades or garden fences. In the following, we have compiled some possible applications:

  • Cleaning cars and bicycles
  • Cleaning tools
  • Cleaning balconies and patios
  • Cleaning heavily soiled windows with low pressure
  • Removal of lime residues in swimming pools
  • Removal of moss and algae from pavements
  • Removal of snow and salt residues on pavements
  • Cleaning garden furniture
  • Removal of graffiti with a special solvent
  • Cleaning of animal fur with low pressure
  • Removal of spider webs
Caution: Never spray terraces or garden furniture from close range with a high-pressure cleaner. The high pressure can trigger the wood glue and cause the wood to become brittle more quickly.

How much does a cordless pressure washer cost?

The range of pressure washers is broad and prices vary widely. While models with a hose connection and low power can be had for low three-figure sums, consumers should plan on a mid-three-figure investment when purchasing a powerful cordless pressure washer with a large water tank. When purchasing a cordless pressure washer, buyers should expect the following costs:

  • Cordless pressure washers in the lower price range: £90 to £150
  • Cordless pressure washers in the medium price range: £150 to £250
  • Cordless pressure washers in the upper price range: from £250 upwards

Internet versus specialist shops: Where is it worth buying a cordless pressure washer?

If you want to buy your new cordless pressure washer outside the Internet, the best place to start is your local DIY store. There, consumers can benefit from personal advice. How helpful this is depends to a large extent on how well the advising employee knows about cordless pressure washers and their features. Apart from the advice, buying in a local store is usually cumbersome. Often the selection of available models is as limited as the possibilities to compare the individual devices with each other. In the worst case, it is necessary to visit several shops to find a suitable battery-powered high-pressure cleaner.

The internet offers better conditions. Not only are almost all currently available models available here, but there are also many opportunities to obtain comprehensive information and precisely compare the individual devices with each other. As soon as the right battery-powered high-pressure cleaner has been found, it can be ordered conveniently and quickly from home. The bottom line is that the advantages of the internet outweigh the disadvantages. This does not mean that a good cordless pressure washer cannot be found in local shops with more effort.

Cordless Pressure Washer Buying Guide: What do you need to consider when buying a cordless pressure washer?

If you want to find a pressure washer that fully meets your requirements, you should consider a few factors. To help our readers make an informed buying decision, we have compiled the most important criteria in the following section. These include:

First of all, the buyer should determine what he wants to use the new battery-powered high-pressure cleaner for. Decisive factors are the place of use and the severity of the soiling. If the device is to be used exclusively for cleaning a specific area – for example, the patio or the car – consumers can use a cordless pressure washer with a hose connection without hesitation.

If different areas are to be cleaned and no specific place of use can be determined, a model with a water tank is recommended. This allows flexible use at different locations. If you already know that you will have to deal with stubborn dirt – for example, mossy pavements or limescale residues in the swimming pool – you should make sure that the water pressure is as high as possible. If you only want to make it easier to remove pollen from your car in spring, you can opt for a model with low water pressure.

Water pressure

The higher the water pressure of a cordless pressure washer, the more effectively and quickly it can remove stubborn dirt. While inexpensive models are usually found in a range between 5 and 20 bar, battery-powered pressure washers from the middle and upper price ranges come close to the performance of normal pressure washers. They operate at 20 to 90 bar. Consumers should note that high water pressure is always accompanied by higher water consumption. This disadvantage can be compensated by the fact that cleaning tasks are completed more quickly.

Different shapes of the lance of cordless pressure washers ensure that users perceive the water pressure to be different. With angled lances, the water pressure has a stronger effect on the wrist and the perceived force is higher. Straight lances put less strain on the wrist and are usually perceived as more comfortable.

Pump material

The heart of a battery-powered high-pressure cleaner is its pump. It should be as stable, powerful and light as possible. The decisive factor is the material. High-pressure cleaner pumps are made of brass, aluminium or plastic. Brass pumps are heavy, but are considered the most durable. They are found almost exclusively in models from the upper price range. Pumps made of aluminium are also robust. The advantage is that they are lighter and less expensive than brass pumps. They can be found in both mid-range and high-end models.

Battery-powered pressure washers in the lower price range usually have plastic pumps. These are inexpensive to manufacture, but less robust and powerful. One disadvantage is that they are sensitive to freezing water. In the worst case, the water can expand so much that the pump bursts. This risk does not exist with brass or aluminium.

The performance of a high-pressure cleaner pump can be determined by its flushing capacity. This is given in litres and indicates how much water the cleaner can deliver per minute. For most models, this value is between 3 and 5 litres. With a low flushing capacity, dirt can be loosened, but the water pressure is not strong enough to effectively remove the dirt.

Tank for cleaning agent

There are cordless pressure washers that have an integrated tank or an external container for adding cleaning agents. Consumers should determine whether such a tank is necessary before buying. Although cleaning agent facilitates the removal of stubborn dirt, it is usually not necessary for ordinary tasks such as cleaning pavements, patios or vehicles. A tank for cleaning agent is important when oily contamination needs to be removed. Accordingly, such models are mainly interesting for use in factories or workshops.

There are special cleaning agents against limescale, moss or tyre marks. If you have to remove such dirt frequently, you can benefit from a battery-powered high-pressure cleaner with an integrated detergent tank.

The spray nozzles

When buying a cordless pressure washer, it is important to pay attention to which nozzles the device is equipped with. While inexpensive models usually only have a spot spray nozzle, pressure washers from the middle and upper price ranges are often equipped with 3-in-1 or 5-in-1 nozzles, which combine several types of nozzles. The most commonly used nozzles are:

  • Spot-jet nozzle – considered the basic type and concentrates the water on a small area. The angle of the orifice is 0 degrees, which means that all the working pressure is concentrated on the area to be cleaned and no power is lost. This makes a spot-jet nozzle very suitable for cleaning joints or grooves.
  • Flat jet nozzle – this nozzle has a gentler, flatter jet with an angle of around 60 degrees. The user can often adjust the angle. In favour of a larger area output, flat-jet nozzles lose some of the working pressure. They are suitable for cleaning large surfaces – for example, floor tiles, tiles or window panes.
  • Rotor nozzle – this nozzle is a further development of the spot-jet nozzle. As the nozzle rotates during cleaning, it combines the jet power of the spot-jet nozzle with the area power of the flat-jet nozzle. This makes it possible to clean over a wide area and almost at the same time as the spot-jet nozzle. This makes rotor nozzles suitable for joints and grooves as well as for surface cleaning. Users should bear in mind that the combination of high pressure and good area performance can cause damage to sensitive or porous surfaces.
  • Combination nozzle – as an alternative to the previously mentioned nozzle types, cordless high-pressure cleaners can be equipped with a combination nozzle. This has an individually adjustable nozzle and can be used both as a spot-jet and flat-jet nozzle. With most models, the desired mode can be set by turning the nozzle head.
  • Shower nozzle – some cordless high-pressure cleaners come with a shower attachment. This works with a low water pressure and fine water jets. This makes it suitable not only for gentle cleaning, but also for watering garden plants.

The water tank

If you decide to buy a cordless pressure washer with a water tank, you should pay attention to the capacity of the tank. On average, this amounts to 10 to 30 litres and should be considered in relation to how much water the pressure washer uses per minute – usually between 3 and 5 litres. Optimally, the cleaner has a large water tank and a low water consumption per minute. This offers the advantage that the tank does not have to be refilled so frequently during longer cleaning tasks.

It should be taken into account that the size of the water tank has a direct impact on the weight of the cordless pressure washer. If you want to use your new cleaning device flexibly at different locations, you should cut back on usage time and opt for a model with a small water tank or a pressure washer with a hose connection.

The water hose

Battery-powered pressure washers with a water tank have a hose that connects the tank to the lance or high-pressure gun. On models without a water tank, the hose is used for the water supply. With both types of equipment, a hose that is as long as possible is advantageous, as this ensures freedom of movement when cleaning. On models with a water tank, the connecting hose is usually between 3 and 6 metres long. Pressure washers without a water tank have inlet hoses up to 15 metres long.

In addition to the length of the hose, it is important to pay attention to the hose connection. With inexpensive models, the hose can only draw water from containers. With many high-quality models, it is possible to connect the hose to a water tap to ensure an uninterrupted water supply.

The battery capacity

The battery capacity is given in ampere hours and indicates how much power a battery can store. For cordless pressure washers, this value is usually 2 to 5 ampere hours. Depending on the power, the devices can achieve runtimes of between 15 and 60 minutes. The manufacturers do not always give precise information about the battery life. In case of doubt, this can be guessed from the power and battery capacity. If a pressure washer has a high battery capacity of 40 volts and a low battery capacity of 2 ampere hours, the battery life is likely to be short.

The weight

Battery-powered pressure washers are designed for mobile use. They should be as light as possible so that they can be transported to the place of use without much effort. On average, the weight of such cleaners is between 7 and 15 kilograms.

Many cordless pressure washers with water tanks are equipped with wheels for easy transport to the place of use.

Which well-known cordless pressure washer manufacturers are there?

In the following section, we would like to introduce three companies that are known for manufacturing their high-quality cordless pressure washers.

Bosch

Bosch is a traditional Stuttgart-based company that has been around for over 100 years. The company is considered one of the largest German companies and a leading manufacturer in the field of electric tools.

  • Can high-pressure cleaners be rented?

    Yes, high-pressure cleaners can be hired or rented for one-off use. If you want to use the device regularly, it is better from a financial point of view to buy a battery-powered pressure washer. It is not uncommon for the rental fee for one day to be in the mid-double-digit range.

Glossary

Spot-jet nozzle

The spot-jet nozzle works with a 0-degree orifice and concentrates the entire water pressure on a small area. This makes this type of nozzle suitable for precise removal of stubborn dirt. Cleaning large areas can be time-consuming with a spot-jet nozzle.

Fan jet nozzle

The fan jet nozzle works with a 60 degree orifice and distributes the water pressure like a fan over a large area. The jet has a lower water pressure and a larger area coverage. This makes the fan jet nozzle suitable for gentle cleaning of large areas. It is less suitable for stubborn dirt.

Volt

The electrical voltage of a battery is expressed in volts. This value indicates how much current the battery can generate to power the electric motor of a pressure washer. The more volts the battery has, the more powerful the device.

Bar

Bar is the international physical unit for pressure. For example, the air pressure at sea level is 1 bar. The water pressure of a tap is around 5 to 6 bar.

Lance

The lance of a cordless pressure washer is the component between the nozzle and the pressure gun. This component directs the water to the nozzle. In simple terms, the lance is the extension of a cordless pressure washer.
