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. Also, this machine comes with two pressure settings – low pressure and turbo.

The most powerful cordless pressure washers operate at 25 bar.Pet owners can also trust the K2 to help them get rid of pesky muddy paw prints across the garden, as well as for smartening up their car or garden furniture.

If you have a cordless jet wash with a built-in water tank, then you need to refill it repeatedly. Plus, you need to clean the tank as well.

These can connect together to create an 18 m hose in total – perfect for a range of jobs! Due to a long cleaning lance, you can easily control the portable washer. This lance has multiple spray angles at 0, 15, 25 and 40. Apart from these angled spray outputs, it has a shower mode. Worx WG629E.1 also comes with a short lance that you can use for watering the garden plants. A washer with more than 22 bar should be capable of removing most types of dirt. A good pressure washer with this power can usually remove algae on patios using a fine ‘pencil’ jet. That is, how large is the area to be cleaned, how soiled is the object? Do you have easy access to a container filled with water or to a river or even a lake?
