A few weeks ago I was questioned by a friend if I knew where she could get a excellent pressure washer for cleaning her greenhouse. I told her that recently it would seem Karcher are the word on the street when it comes to jet washes and pressure washers.

But let’s investigate further. It would seem that Karcher have really gone to town with advertising over the past year. I don’t reckon I’ve seen a football game on TV all season with out seeing a Karcher advert on a bill board at the side of the pitch. Not to meantion there huge marketing ploy to clean Mount Rushmore in the USA. I bet that job took a large amount of pressure washing equipment.

My local town counsel also use high pressure washers to remove graffiti and for use as gutter cleaners. I’ll bet you can guess which name is on there huge yellow machines. They’re all Karcher pressure washers!

Next Karcher have been touting recently that they’re going to be cleaning nelsons column with there high power pressure washers. Karcher say each machine used to clean the column is using a 3 high pressure extension hoses at over 60 metres in length. I reckon that’s quite a feet. As anyone who uses pressure washers recently will know. The long high pressure hose you have the more bars in pressure you lose. (Pressure is measured in bars, with lighter cleaning jobs such as a dirty car needing around 100 bar, while tougher and harder to reach jobs like the roof needing at least 120 bar. )

On of the fantastic things about Karcher, is there innovation. I was talking to on of there reps a few months back and they have a fantastic small thought on the horizon. Why pay all that postage and package for 10 litres of liquid detergent. Karcher have a better thought. Freeze dry the detergent.

Hot water pressure washers clean quicker and more thoroughly using significantly less both water and chemicals, while. Cold water pressure washers have power to quickly remove grime, dirt, debris, stripping paint, rust, mildew and other buildups in numerous residential and commercial applications. Generally, but, the more pressure the machine delivers, the more power it has to lift dirt.

Hot water pressure washers are ideal for cleaning heavy equipment such as pumps, gearboxes, turbine blades and dams in hydroelectric plants If you want to wash large decks and clean siding a Karcher will suit you fantastic.

What about reliability? Expert reviews emphasize that the quality of the pump is the most vital factor in how long you can expect a pressure washer to last, with motor or engine quality secondary. Karcher pumps and motors really do last for ever. So I wouldn’t worry about that.

There are so many pressure washer models that there’s small consensus among reviews. But I’m not fence sitting. I’m pro Karcher and proud. I recommend you get one as soon as you can.

Pressure washers can be used for a variety of indoor and outdoor commercial and industrial cleaning jobs. For outdoor applications such as cleaning sidewalks, parking lots, driveways, and building exteriors, a pressure washer is simply the best option. But, finding the right pressure cleaner for use outdoors can be a bit more complicated. The following are some tips to select the right power washer for outdoor cleaning and graffiti removal jobs.

Mobile or Stationary

One can classify pressure washing machines based on their portability as mobile and stationary equipment. Mobile machines are best suited for outdoor cleaning jobs, as operators can more readily reach different areas. Mobile equipment can be further classified into wheel-mounted machines and truck- or trailer-mounted machines.

Wheel-mounted machines, as the name suggests, have wheels attached to the base. The operator can push these machines to transfer them from one place to another. This is ideal for small-sized machines.

For larger machines, it is better to select truck- or trailer-mounted equipment. It makes the cleaning job much simpler since these machines can be transferred via means of a vehicle.

Output Temperature

There are three types of industrial pressure washers according to output temperature: cold water, hot water, and steam pressure washers. Cold water pressure washers provide an output temperature at room temperature; hot water machines have an output temperature of 210°F, while steam machines have an output temperature of 330°F.

Of these three machines, steam output is the most powerful as it readily dissolves stubborn deposits. After all, cleaning power increases as temperature increases.

To reap the benefits of all three machines, a tri-mode system is best. Tri-mode pressure cleaners offer all three kinds of output: cold water, hot water, and steam, to meet varying applications.

Power Level

The output pressure level of a power washer is vital in determining its power. The output pressure level can vary from 500 psi to 8000 psi. Higher pressure levels translate to higher cleaning power. Since each application is unique, pressure levels must be selected on the basis of the intended application.

Another specification closely related to output pressure is the flow rate. It is a measure of the quantity of water that flows through the output of the machine, expressed as gallons per minute (GPM). Usually, the flow rate increases along with the output pressure. In some cases, where drainage facilities are poor, one may have to select a machine with a low flow rate.

Graffiti Removal

Removing graffiti and stains from compound walls and sidewalks is very common outdoor cleaning job. One can find commercial pressure washers specially designed for the task of removing graffiti. These machines can blast away nearly all types of graffiti and stains.

One can further improve the graffiti removing capability of these machines by using a green graffiti remover chemical in conjunction with the system. These chemicals do not cause any harm to the environment or the operator, and are produced from plants and vegetables. The green chemicals contain lifters and emulsifiers to encapsulate and emulsify paint molecules, bringing them to the surface to be blasted away.

To better match a machine to your specific applications, it is best to contact a product specialist at one of the industry’s top suppliers.

Commercial and industrial users alike often face a variety of indoor pressure washing applications. After all, the facilities in which these users work and operate must be cleaned. But, many pressure washers on the market are not ideal for indoor applications.

Gas pressure washers afford users immense power and mobility as a result of a robust gasoline engine capable of being operated far from an electrical supply. But, gas pressure washers are also incredibly noisy and produce exhaust. This noise and air pollution makes pressure washing machines powered by gas not well suited for the indoor environment.

A much quieter and safer alternative is pressure washing equipment powered by electricity. These machines can generate the same cold water, hot water, or steam heating options and high pressure levels and flow rates as gas powered units without the added noise. In fact, electric pressure washers can even be used in schools, hospitals, nursing homes, and more for a wide variety of pressure washing tasks. In many cases, in facilities where the level of noise must be considered, these tasks would remain incomplete if gas powered systems were the only option.

Electric powered, industrial pressure washers offer an additional benefit – they produce no harmful exhaust. They can be used inside virtually any commercial or industrial facility without harming the indoor air quality or endangering the health of users, employees, or customers.

Even though these electric machines are less noisy and produce no exhaust, they still pack quite a punch when it comes to getting the pressure washing job done. Like all pressure washing equipment, temperature options available with these units include cold water, hot water, and steam. Cold water pressure washers are ideal for lighter applications, but prove to be inefficient for heavier degreasing applications.

For more challenging tasks, heated pressure washers are required. Hot water models are capable of reaching up to 210°F to dissolve substances and render them simple to blast away with the highly pressurized water. Steam pressure washers offer even greater power, capable of reaching temperatures up to 330°F. These machines sanitize and disinfect while cleaning to greatly speed up the process. This results in the cleanest environment for virtually any commercial or industrial application.

Indoor operators of pressure washers aren’t limited when it comes to features either. Wet sandblaster pressure washers can be bought in electric configurations for the removal of rust, corrosion, and other heavy deposits on metal surfaces indoors. Machines can also be bought with an additional acid-feed or phosphatizing feature to pre-treat metal surfaces before the user applies paint primer or powder coating.

When comparing models, make sure to shop at a supplier offering a wide variety of choices to ensure you find the right machine to suit your needs, no matter what the application.

Over the years, companies have introduced new technologies and mechanical changes to pressure washers.  Because of this, there are a variety of models and categories available today. These include commercial pressure washers, industrial pressure washers, steam pressure washers, hot water machines, and cold water pressure washers, to name a few.

Some of the latest models are classified based on the technologies they feature. Several new technologies make using these pressure cleaners far simpler than older, conventional models. Some of these technologies include: low flow technology, tri-mode functionality, and super-high steam temperatures. But, there is one technology that stands above the rest – automatic shut-down.

What Is This Technology

Preferred by cleaning professionals and all users of electric commercial pressure washers and industrial pressure washers, automatic shut-down technology reduces wear and tear on key components to prolong the machine’s life. To know this technology fully, one needs to know how a pressure washer works.

Functioning of a Pressure Washer

A pressure washer device pumps water at various temperature levels (cold water, hot water, or steam) across surfaces at high pressure levels to wash away the dirt, dust, stains, and other impurities.

The high levels of pressure are obtained through a pump, which pumps water through a nozzle onto the surface. A gasoline or propane engine or an electric motor powers the pump. The output is ejected onto the surface through a trigger gun connected to the actual machine through a pressure hose.

A Practical Problem

In conventional pressure washer machines, the operator can stop the output flow by using the trigger of the gun. But, even if there is no output flow, the machine’s pump and motor are still on. To reduce wear, the operator must return to the machine during each break to switch it off.

This is highly inconvenient when cleaning large buildings and areas with long hoses. The operator may even want to stop the work temporarily. Either the machine stays on or the operator must go back to shut the machine off each time. The latter option is inconvenient. The former option is harmful to the machine, as it may suffer much wear and tear and may result in wastage of power.

A Solution

Automatic shut-down technology offers a solution to this problem. Like all pressure cleaners, operation of the machine is controlled through the trigger gun. But, when the machine is not in use for more than 30 seconds, machines with this technology shut down automatically. When the trigger is squeezed again, the machine starts up.

This technology allows the operators to shut the machine on and off for temporary work stoppages. This functionality effectively reduces wear and tear on the pump and motor, the key components of the machine. A reduction in wear translates to greater longevity.

It is vital to note that this technology is only available in electric versions of tri-mode, hot water, cold water, and steam pressure washers. To learn more about this advanced technology, search the internet for trusted suppliers of high quality pressure cleaning systems

There are two different types of pressure washing. One type uses cold water to clean and the other utilizes hot water for extra cleaning power without the need for applying more pressure. So what do you need to know about these different cleaning methods and which do you need?

The first thing is to clarify what is meant by the terms hot and cold water cleaning. Knowing the difference will help you know and choose which one you will need.

To provide hot water pressure washing you need a specific type of pressure washer with a burner that will heat the water that is supplied. These burners usually run on kerosene or diesel fuel, but can also be powered by natural gas or electricity. They are capable of heating water in excess of 200 degrees so caution must be used when using this type of equipment. These machines are usually quite large and can weigh over 1000 lbs.

Most cold water machines are much smaller and portable since they do not have a burner and the temperature of the water supplied remains constant. This makes these types of pressure washers much safer for do-it-yourself enthusiast.

The main difference between these machines depends on the substrate you want cleaned. Please know that you can not clean just anything with pressure washers, especially when it comes to hot water systems. Here are some various things each of these cleaning techniques may be used for.

1. Hot water pressure washers are brilliant for cleaning impervious surfaces such as concrete and are the simplest way to remove gum and oil stains without causing hurt. Hot water washers are brilliant for commercial cleaning applications as well. They allow for a more thorough cleaning of driveways, sidewalks and walkways which help present customers with a clean image from the time they arrive.

2. Cold water pressure washers are brilliant for residential cleaning applications. In combination with the proper soaps they are fantastic for cleaning all types of siding such as vinyl, drivit, stucco, and aluminum. As long as there is no gum or major oil staining, cold water is also fantastic for cleaning porches, walkways, patios, pool decks and much more.

Hot water offers no better cleaning than cold water systems for parts of your home such as siding. This means there is no benefit for a homeowner to use this type of cleaning method. The only benefit is for the contractor, as in some cases it can speed up the cleaning process and save them time. This is a savings that is usually not passed along to the home owner either.

Most commercial concrete cleaning applications require the removal of gum and oil. There is no better way to remove these without causing hurt than a hot water pressure washer.

The type of pressure washing method you will really need depends on whether or not you are a home owner or a business owner along with what it is that you need cleaned specifically. So now that you know the difference, you will not have to worry about paying for a service you do not need.
