When a corded pressure washer is better
A powerful cordless pressure washer can handle almost any cleaning task, so now the question arises: when is a corded 230 volt pressure washer worth it?
This question is relatively easy to answer: When a low purchase price is important or longer periods of use are necessary.
In addition, even the most powerful cordless pressure washers are not necessarily suitable for cleaning pavements or car parks.
For washing vehicles, the capacity is often too low, which is why battery-powered models are not well suited for this purpose. So if you plan to clean your vehicle or car park often, you should rather use a corded device.
The most important features of a battery-powered pressure washer
The performance data: Pressure & litre capacity
As with every pressure washer, a battery-operated high-pressure cleaner also has data on the maximum pressure in bar and the maximum litre capacity in l/h. These two data provide information on the performance of the pressure washer. These two data provide information about the performance of the high pressure cleaner.
In general, the litre capacity is much more important than the maximum pressure when evaluating the performance. However, there is a peculiarity here, because below 50 bar the pressure is more important than the litre capacity.
The battery’s volt number is often used in advertising. A high volt number gives an indication of the performance of the model, but the pressure and litre capacity are much more important.
The battery life / performance data of the battery
If a manufacturer gives information about the battery life, you must always pay attention to the indicated power level.
Often a lower power setting is chosen in order to artificially “stretch” the battery life during measurement. The manufacturer assumes that the maximum pressure is not required for every cleaning task.
You should not place too much trust in the battery life indicated by manufacturers from the Far East. However, you have one indication with which you can largely estimate the battery life. This is the mAh rating.
The higher the mAh, the more capacity the battery has. A higher capacity usually corresponds to a longer runtime. However, the power consumption plays a decisive role in the battery life. If the power consumption is too high in relation to the battery capacity, the battery life will be shorter.
Other important features:
Pressure regulation
A sensible pressure regulation is the most important element of a powerful high-pressure cleaner.
If too much pressure is applied to a sensitive surface, it can cause permanent damage. However, this is only the case with powerful pressure washers.
Therefore, you can safely regulate the pressure of most cordless pressure washers with the distance or so-called plug-on nozzles.
Precise pressure regulation is only necessary when pressures of over 85 bar can be reached by the cleaner.
Suction function
The suction function is one of the most popular features of a pressure washer. It allows you to use external water sources such as a rain barrel or a river. You are therefore independent of the regular house water connection. To support this function, a so-called suction hose with a non-return valve is recommended.
Water tank
The “alternative” to a suction function is an integrated water tank. The great advantage of such a tank is that you do not need an external water source. You can therefore use the cleaner everywhere independently.
However, such a tank has two decisive disadvantages. When full, it makes the mobile pressure washer much heavier and thus more unwieldy. In addition, it is in principle only suitable for less powerful devices. Most water tanks have a maximum capacity of 14 litres, which is used up within a few minutes with powerful devices.
Therefore, when buying a powerful device, make sure that it can also be operated with a water connection or that it has a suction function.
Detergent suction or tank
The detergent suction function is often overlooked at the time of purchase. In addition, it is available on almost every full-fledged high-pressure cleaner.
There is another version with the same functionality. Namely, as a cleaning agent tank.
The difference is that with an integrated tank, you don’t have to lug around an extra detergent container.
Both systems work in the same way. A detergent is added to the outgoing water, which significantly increases the cleaning performance.
This allows you to use detergent without having to use an extra sprayer.
Replaceable battery
The last but one of the most important features of a cordless pressure washer is the replaceable battery. If you can change the battery quickly and easily, it gives you two big advantages.
On the one hand, you can simply replace an empty battery with a full one and continue working without interruption. In addition, replacing a defective battery is child’s play.
As a rule, they need to be replaced around 3 years after intensive use.
The 2 most practical accessories for a cordless pressure washer
Dirt cutter for battery-powered pressure washer
The dirt cutter is one of the most important accessories for a less powerful high-pressure cleaner.
It increases the cleaning performance enormously, even at low pressure.
This will enable you to clean stones and stone walls quickly and effectively even with an 85 bar battery-powered high-pressure cleaner.
Suction hose / suction hose
You can use the suction function with a normal garden hose. However, a suction hose will definitely make the job easier. This is because a suction hose has a non-return valve which prevents the water from flowing out of the hose in an uncontrolled manner. This prevents the pressure washer from “drawing air”.
This is crucial because the suction function works with the help of a vacuum. When the pressure washer sucks the water through the hose, a vacuum is created which sucks new water through the hose. However, this vacuum can only be created when the hose is full of water and this is exactly what the non-return valve ensures.
What are the advantages and disadvantages of a cordless pressure washer?
FAQ
Which cordless pressure washer is the best?
If you are looking for a powerful cordless pressure washer, there are two excellent models: the WORX pressure washer and the Yard Force. Both don’t give each other much and are the top models in their field.
How much does a cordless pressure washer cost?
The purchase costs of the bare cordless pressure washer are usually not too high. Here you can expect about £150 for the powerful models. However, this price does not include a single rechargeable battery, for which you often have to pay £100.
What should I pay particular attention to when buying?
You should pay particular attention to the performance of these battery cleaners. This means how much pressure it can build up and what litre capacity is available. In addition, the battery life is a decisive factor, if this is not given, you can orientate yourself on the mAh of the battery to at least have a point of reference. Furthermore, such devices should definitely have a replaceable battery.
