Product Information

Have you ever tried to clean a heavily soiled patio or driveway with a garden hose? Then you must have noticed that the water consumption was enormous, but the result was usually not what you expected. Since not all manufacturers state the working pressure and this is often only stated for higher-quality pressure washers, we have decided to show only the maximum pressure in our tables. Otherwise, the professional devices would perform superficially worse in comparison to the cheaper models. Pressure regulation, the most important feature in a powerful pressure washer

In addition, the higher the maximum pressure of the device, the more difficult and therefore more expensive this becomes. However, the delivery rate should always be in proportion to the maximum pressure, otherwise only spray mist will come out of the nozzle after a short distance. As you have read above, this would exactly counteract the sensible effect of a pressure washer with more pressure (bar). You’ll have gathered by now that I don’t like all the messing about with plugs, wires, taps and hoses. I can’t be the only one and that’s why Bosch’s cordless, genuinely portable unit has its own niche. The accessories for a home pressure washer can make a big difference when it comes to expanding the capabilities of a given jet washer. Even some of the light-duty electric pressure washers are that much more efficient and effective when they have accessories that will allow people to redirect the pressure. Evaluating the pressure washers as a whole will allow people to make more informed decisions. It’s easy to dismiss washing a car with a pressure washer as just being about convenience. But in many ways, pressure washing is the best way to revive your car’s appearance. For starters, using electricity to make the water work harder dramatically reduces the volume of water used, compared with traditional hose rinsing. So not only is less water wasted, but also your car’s hidden, slow-drying cavities will get much less drenched. And for blasting away the salt-rich dirt that clings on beneath sills or under wheel arches, a pressure washer is essential. A blast from a well-aimed lance will dislodge what a hose will simply dampen.In all honesty, a less powerful Kärcher like their 145 bar K5 or 130 bar K4 is enough for most household jobs and some come bundled with soft car-cleaning attachments, which this doesn’t. But I had to make it the overall winner because, for anyone asking “what is the best pressure washer?” this is it. We recommend a minimum of 1200 PSI – or 83 Bar – to get the best results. At the high end, we suggest an upper limit of 2400 PSI – or 165 Bar. All of the products we review here fit within that power range. For older cars, classic cars, or cars that already have damaged paintwork we suggest using water pressure on the lower side in case a high pressure causes damage. Store your power washer in a dry place that is well ventilated. In the winter months you may want to bring it inside or store it somewhere that is heated to ensure the pump does not freeze and become damaged with any water left inside. Should I buy a pressure washer? The big selling point of the Worx Hydroshot is convenience. It could easily be taken on the move and used to clean bikes or outdoor gear. bar and 360 l/h flow rate is what a pressure washer should have at least for normal household use. However, if you only want to clean your bicycle and garden furniture, you can get by with less. However, if you need the pressure washer for larger tasks around the house, you should go for one with more power. What are the benefits of high pressures?

Electricity is by far the best way to power pressure washers for cars. This is because gas-powered devices are much more powerful and likely to cause damage to paintwork. Gas-powered pressure washers are mainly used in industrial applications. How much bar you need depends largely on the area of application. We have therefore created a table below where you can see the tasks and our recommended bar figures. But be sure to read the whole article so that you can understand our recommendations. Recommended pressures (bar) table Area of applicationBonuses include a 18V Power For All battery (sold separately) which is interchangeable with other power tools You get a lot for your money: an extendable lance with two nozzles for gentle and high-pressure cleaning, a foam sprayer, a soft brush attachment and a small patio cleaner attachment. Other accessories sold separately include a roof cleaner, multi-brush kit for cars and garden furniture and a long, flexible tube for cleaning drains and pipes. If you plan to wash down the patio or drive , then the higher pressure will be very useful in this instance to remove tough dirt, so the upper end of the range would be ideal for this.

Basically, the more stubborn the dirt you have, the more water pressure you need. Also, the larger the area, the more comfortable the handling of the device should be. Here, the larger models are certainly more suitable than the small, entry-level models. As you can see in the table, a pressure of about 100 bar is needed for most tasks. But why are there so many pressure washers with more than 100 bar? The reason is actually quite simple. Because with a higher pressure you can clean larger areas faster. Yes. Except for industrial use, these days all the best power washers – as they are sometimes known – are electric. Many are cordless, but they are not as powerful as plug-in electric models and the runtime can be limited.People who are only interested in cleaning off their garden furniture, garden tools, motorbikes, bicycles or rubbish bins are probably only going to need light-duty pressure washers that don’t even reach 1500 PSI (pressure: pounds per square inch). This means that with a pressure washer for home use, you not only save time, but also quite a lot of money. What is a lance on a pressure washer? The maximum pressure of a pressure washer indicates the maximum pressure the unit can reach. For example, if the water flow is interrupted, a high pressure can build up in the unit for a short time. This is then calculated or measured and is output as the maximum pressure. Mainly the big manufacturers (Kärcher, Bosch, etc.) offer a variety of tools that make high-pressure cleaning easier. The K7 along with other models at the top of the Kärcher range comes with Smart Control, linking it to a phone app. Being old, I’m generally against that kind of thing but this app is helpful. Tell it what you’re cleaning – car, bike, wood, glass, stone and so on – and it will tell you what attachment and what settings to use and how to get the best results step by step.
