Product Information

If you decide to buy a portable 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. 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 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. 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.

Gone are the days of being tethered to power outlets or dealing with cumbersome cords as you attempt to clean various surfaces. With the advent of cordless pressure washers, cleaning your car, patio, garden furniture, or any other outdoor area has never been easier. These portable powerhouses provide the freedom to roam without sacrificing the powerful cleaning capabilities that traditional pressure washers offer. 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.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 battery capacity is given in ampere hours and indicates how much power a battery can store. For portable 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 DEWINNER is a brand offering angle grinders, electric grass trimmers, and pinpointing metal detectors to customers. This DEWINNER review will thoroughly examine the brand and its products. It will also look at the product selection, price, and more to help you decide if their products are worth buying. 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 battery-powered pressure washer, buyers should expect the following costs: 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.

Different shapes of the lance of battery-powered 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 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. 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: 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. 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.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? 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
