The high pressure washe can also be used as a high-powered device for artists. With the help of templates or the application of a special technique, it is possible to create large-scale illustrations. The reverse graffiti does not portray superstition, and just wash it.
The many fixtures on the wall presented a challenge as they provided an irregular surface to work on. As different parts of the wall had different levels of dirt, the artwork had to be positioned very precisely. In order to reach all of the different parts, the artist and the industrial climbers helping him abseiled down from the crest of the wall. It was mostly organic dirt such as algae, lichens and moss that needed to be removed from the dam – a job that could be carried out without the use of chemicals.
The port town’s and pier’s long history inspired the artist’s subjects: he chose different local personalities with ties to the shipping or fishing industry, who have especially expressive faces.
Roll out the pressure washer! Many people now routinely use these super-powerful hoses (also known as "power washers") to blast things clean with water jets pressurized at about 100–200 times the pressure of the air around us (that's 1500–3000 pounds per square inch or psi). They're brilliant on patios, drives, lawn furniture, barbecue grills, and all kinds of other outside grime. Let's take a closer look at how they work!
Why pressure jets get things cleaner
That's when a pressure washer comes in really handy. It uses a narrow, high-pressure jet of hot or cold water to blast dirt free. Because the water is traveling fast, it hits the dirty surface with high kinetic energy, knocking dirt and dust away like a constant rain of tiny hammer blows. It's only water, though, so it doesn't damage most hard surfaces. Having said that, it's a good idea to test a pressure washer on an inconspicuous area before you start work to make sure it doesn't harm the surface you're cleaning. Always read the instructions before you use a pressure washer!

A pressure washer is less sophisticated than it sounds. It's really just a water pump powered by an electric motor. The washer takes in ordinary water from a faucet (that's a tap to you folks in the UK), the pump accelerates the water to high pressure, and then squirts it from a hose at speed through a trigger gun. You can fit various other attachments to the end of the hose for cleaning different things.
These, then, are the main parts you'll find inside a pressure washer:
Water inlet: A hose that connects the pressure washer to the main water supply. There's usually a filter in the inlet to stop dirt and debris entering the washer and clogging up the works. Little bits of grit are the last thing you want inside your washer—especially since they could come blasting out of the other end at high speed!
Electric motor or gas engine: Most smaller, pressure washers (such as the very popular ones made by Kärcher) run off the domestic electricity supply, but bigger models are powered by compact gasoline engines. The engines are similar to the ones you'd find in lawnmowers (typically power rated at around 3–4kW or 3.5–5.5HP). Gas engine models are great if you're working outside in places where an electricity supply is hard to find (or where a long trailing cable would be dangerous or inconvenient). The motor or engine is designed to power the water pump.

Here's the engine inside a typical gas-powered washer used by the US Marine Corps being refilled ready for cleaning helicopters. This one's made by Jenny and rated at a pressure of 3400 psi (roughly 230 times normal atmospheric pressure), which is about three times more than an average home Kärcher. It's just about the most powerful washer you'll come across! Photo by LCpl. Jesse D. Leger courtesy of US Marine Corps.
Water pump: This is the heart of a pressure washer. It's a bit like a hand-operated ground-water pump—only it's driven at high speed by the electric motor (or gas engine) instead of your hand. When the engine pulls the pump one way, it sucks water in from the faucet; when it pushes the pump the other way, the water squirts out in a high-pressure jet. Pumps are designed to handle a water flow of around 4–8 liters (1–2 gallons) per minute.
High-pressure hose: This is the tube that runs out from the washer to whatever cleaning attachment you've decided to use. An ordinary bit of tubing wouldn't be able to survive the high-pressure of the water flowing through it. High-pressure hose is reinforced with wire mesh and has two or more layers of high-density plastic. It's important to use hose that has a higher pressure rating than the pump in your pressure washer but, if your washer came with your own hose, there shouldn't be anything to worry about. Typically, the safety margin on pressure-washer hoses is about 300 percent, so if your washer is rated at 2000 psi, your hose should be able to withstand pressures of at least 6000 psi.
Cleaning attachment: Depending on what you're cleaning, you can switch from a simple trigger gun (essentially just a valve that lets water through only when you squeeze the handle) to a spinning wand spray or a rotating brush to scrub your drive. Powered attachments are driven by the force of the water flowing through them. For less noise

Real time work
The pump squirts out the hot, soapy water through the reinforced, high-pressure exit hose (and whatever attachment is fixed onto it). The narrow nozzle on these attachments helps to increase the pressure of the water jet even more. The high-pressure of the jet not only cleans more effectively but means you're wasting around 80 percent less water than if you used an ordinary low-pressure hosepipe (which is more economical if your water is metered).
All benefits and drawbacks of high pressures
High pressure washers is good for celaning different surfaces
Deep cleaningThey use a lot of water (typically 4–8 liters or 1–2 gallons per minute). That water needs to move away quickly, so you'll need good drainage where you're working if you don't want to cause a flood.
High efficenceAlthough power washers are insulated and very safe to use, there's always a risk of using electricity near water, so be sure to work with an RCD unless you're using a gasoline-powered machine.
WaterThey can make everything around them (including you!) very dirty by blasting filth in all directions. Think carefully about the order or direction in which you'll be working to minimize how much cleaning up you'll need to do later. Choose your attachments wisely to avoid making too much mess, and be sure to wear waterproof, protective overalls and shoes.
Easy handling.Pressure washers are blunt instruments, not always suitable for cleaning delicate fixtures and fittings. Used the wrong way, they can damage wooden decking and penetrate the weakening seals of old windows, making them more prone to leaks or (in the case of double-glazing) "fogging up." If you're unsure, try your washer on an inconspicuous area first—and use with a low-power setting (or a wide nozzle) before upping the power (or using a narrower nozzle) once you feel it's safe to do so.
Many nozzlesThe use of special nozzles allows you to effectively clean seams and other hard-to-reach places, completely removing dirt, rust, plaque and fungus.
The company Kärcher, which stands in the east of high-tech technologies and produces flagship pressure washers has introduced a novelty. Only small and compact high-end devices, which can compete with the popular K2 serial model.
The package contains few separate components, and they’re self-explanatory: there’s a five-metre high-pressure hose, a spray gun, two additional nozzle attachments, a garden hose connector adapter and a clip-on accessory holder. The pressure washer itself is quite small and correspondingly light. It weighs just 3.9 kilogrammes (4.7 kilogrammes with accessories). In addition, it comes with a power cable and an on/off switch. Nice and simple.
Thanks to its compact size and low weight, it can be transported and stored easily. The little power bundle is ideal for cleaning balconies, garden and patio furniture as well as bicycles and small cars quickly and efficiently. Its handling is self-evident: The spray gun, extension tube and Vario Power spray lance can be assembled in just a few steps.
Appropriately for the urban lifestyle, thanks to its especially small dimensions and the detachable storage box for accessories, the K Mini finds its place in every apartment, however small – without loss of performance: With a maximum pressure of 110 bar and a maximum water volume of 360 litres per hour, even stubborn dirt is removed.
As a part of the fight against the spread of coronavirus, eight nursing homes in Armenia have received high-efficiency disinfection equipment. Kärcher provided disinfection equipment to nursing homes in Yerevan, Abovyan, Vanadzor, Gyumri, Akhuryan and Tashir. The purpose of the action is to protect the older generation at risk.
The official representative office of Kärcher in Armenia informs that the initiator of the charity is the asset management company C-Quadrat Ampega Armenia, which mainly manages pension assets in Armenia. Taking into account the situation caused by the coronavirus epidemic, in which the elderly are most vulnerable, as part of the corporate social responsibility of the company, it supported 8 nursing homes and day care centers in the Republic of Armenia.
The initiative was implemented under the auspices of Ernst-Ludwig Dries, Andreas Wimmer, Board Member of C-Quadrat Ampega Asset Management Armenia, with technical support from Caritas Armenia. The event was sponsored by the German charitable organization Noah, represented by members of the executive board Johannes Kercher and Gevorg Hayrapetyan. The nursing homes were provided with steam generators that allow not only effectively cleaning surfaces from various types of contaminants, but also disinfecting surfaces. It is important to note that the steam cleaner does not require special detergents and disinfectants, which often cause allergic reactions. The main weapon is high pressure steam, which kills up to 99.9% of bacteria and viruses.
This promotion is not the only initiative of Kärcher. The company provides assistance with the first stage of the spread of coronavirus in Armenia. Thus, the appropriate disinfection technique was also provided to the Nork Infectious Diseases Hospital. Kärcher's social assistance programs include helping large families, church organizations and much more. One of the following programs may be a program of cleaning monuments in the capital. The project will be implemented using the company's equipment and resources. Benefactor Johannes Kercher is an old friend of the Armenian people, such charity events are held not only in Armenia, but also in many other countries of the world.
Anyone who grabs cloths and a vacuum cleaner does so with anticipation of the result: a clean home where you can relax and feel happy. But the journey is often the reward: for many people the cleaning process has a stress-reducing effect. For example, 75 percent of Brits state they always mop when they are stressed. With the result that 84 percent feel calmer and more relaxed in a clean home. Also in France there is a connection between cleaning the house and stress relief: 59 percent of the French even describe themselves as meditative and calm during the cleaning process. The international cleaning study, which was conducted by Dynata on behalf of Kärcher in eleven countries, reveals this and many other findings.
Cleaning, but thoroughly
Two thirds of Germans clean at least once a week - 13 percent even do so on a daily basis. The study shows: Saturday is not the alleged "cleaning day", actually only 9 percent of Germans have a set day for cleaning. This doesn't change the result: 88 percent of the local respondents attach huge importance to a clean home.
Cleaning is also celebrated in China. Here deep cleaning, for example with a steam cleaner, is very important – 94 percent of the respondents consider this intensive approach important or very important. In the 25-34 year old category almost all respondents share this sentiment (99 percent). Which living area should be cleaned thoroughly? The kitchen with 41 percent, the bathroom and bedroom, each with 25 percent.
How long the world spends cleaning
All over the world house cleaning takes as long as an average cinema visit, an extensive walk or a coffee date with friends.
Worldwide people spend on average two hours and fifty two minutes cleaning per week. At 4 hours 49 minutes the Russians spend the most time cleaning their own four walls. This hardly comes as a surprise. Cleanliness is important for 97 percent of Russians. People also spend a lot of time cleaning in Belgium: at 3 hours 39 minutes the respondents are among the leaders - and yet 45 percent of them wish they had more time for the household. On an international comparison, the Japanese attach the least amount of importance to a clean home - which is also reflected in the cleaning duration: it is 1 hour 29 minutes in the land of smiles.
Classic helpers versus state-of-the-art technology
The appropriate helpers ensure cleaning is simple and effective. Worldwide people cannot do without manual tools such as brooms, brushes, mops, etc. (79 percent), chemical detergents (75 percent) or electrical cleaning equipment with cable (66 percent) – these are used most by all respondents. However, the trend is clearly heading towards cordless devices. In Japan, electrical helpers with battery are very popular - every second Japanese person (54 percent) considers their use important, one third (34 percent) already rely on them. The opinions on autonomous cleaning solutions such as robotic vacuum cleaners vary greatly from country to country – their services are used most frequently in China by far at 38 percent. In Germany, the use remains static compared to the previous year at only 15 percent.
In contrast, other countries rely on the support of fellow human beings, above all in Poland: every second person (52 percent) here relies on help from a partner, family members or housemates.
About cleaning behaviour
For several years, the international Kärcher cleaning survey has been providing information on the topics of people's cleanliness, orderliness and cleaning behaviour. In this year's survey, which was commissioned by Kärcher and carried out by Dynata in eleven countries, the following result in particular stands out: Cleaning leads to relaxation, and even meditative states. This is said by at least 75 per cent of the English and 59 per cent of the French. Cleaning as a compensatory feel-good activity? Kärcher wants to know more, and asked Dr. Brigitte Bösenkopf, psychologist, journalist and head of the Stress Centre in Vienna.
Pressure + Speed + Temperature = Ultimate Clean
The secret of steam cleaning lies in the powerful combination of pressure, speed and temperature. Microscopic steam particles force their way into even the tiniest areas to thoroughly loosen dirt particles.
Our steam cleaners do not use any chemicals – they use only tap water. This provides a safe environment for small children in particular, who like to put things in their mouths. Allergy sufferers can also breathe a sigh of relief.
If used properly, Kärcher steam cleaners like the SC 3 can remove up to 99.999% of enveloped viruses1, such as the coronavirus or influenza, and up to 99.9% of common household bacteria2 from hard surfaces.
Germs don't stand a chance
Germs don't stand a chance
Sometimes the best way of getting rid of germs is also the simplest: hot steam. The forceful ejection of steam, combined with nozzles and cleaning cloths, ensures that Kärcher steam cleaners remove up to 99.999% of enveloped viruses*, such as the coronavirus or influenza, and up to 99.9% of common household bacteria** on hard surfaces, fittings, tiles, mirrors and more.
This has been confirmed by scientific studies – with Kärcher steam cleaners, germs don't stand a chance. Chemical-free cleaning made easy!

Kärcher steam cleaners are not just for kitchen and bathroom surfaces – they also ensure maximum cleanliness and hygiene on hard surfaces like stone, tiles, vinyl, laminate and varnished wood flooring.
The Kärcher floor nozzle is fitted with slats so that the steam remains concentrated on the floor and is used to maximum effect. Thanks to their unsurpassed cleaning performance, Kärcher steam cleaners are considerably more hygienic than a regular mop or spray mop.
The need for speed
Other popular steam cleaners can take up to eight minutes or more to fully heat up and produce steam. If you've just finished cooking and want to do a quick kitchen cleanup, who wants to wait eight minutes?
And if you've finally committed to cleaning the bathroom, waiting that long might just make you put it off for another day.
Kärcher steam cleaners heat up and produce steam in as few as 40 seconds! In fact, you might even be done steam cleaning before a competing machine fully heats up. Truly timesaving.
A competitive edge
Cheap steamers cut a lot of corners, especially with nozzles. When you attempt to clean the floor, you can see the nozzles making lines of steam instead of covering the entire area.
Kärcher steam cleaners use Lamella Technology to ensure the steam is equally distributed throughout the cleaning cloth.
In addition to getting to an even clean, you also get effective edge cleaning. So go ahead and clean those baseboard edges while you're cleaning the floor. No extra tools required!
