Uses of Pressure Washers


Pressure Washing is also known as ‘Power Washing’. It is  the use of high-pressure water spray to remove loose paint,  grime, dust, mud, chewing gum from buildings , vehicles and concrete surfaces.

The basic pressure washer consists of a motor that drives a high-pressure water pump, a high-pressure hose and a trigger gun-style switch.  A pressure washer creates high pressure and velocity. The pump cannot draw more water from the pipe to which the washer is connected than that source can provide: the water supply must be adequate for the machine connected to it, as water starvation leads to cavitation damage of the pump elements.




pressure Washers are classified into following groups based on the type of energy they consume.





Ultra high pressure

Should You Get 3000 PSI Pressure Washer or 4000 PSI Pressure Washer?

There are things that are more important than cleaning your driveway or that stain in your patio. The problem is cleaning these surfaces take time if you don’t have specialized equipment like a 3000 PSI pressure washer. A lot of people are misinformed about these wonderful pieces of cleaning equipment though.

Not only do a lot of people think that these are unnecessary, they also believe that they’re not worth the investment. Some would rather just get help from professionals to clean what needs to be cleaned in their homes. In actuality, a pressure washer is easy to operate and in the long run is more economical than hiring professionals.

Choosing the Pressure Washer with the Right PSI

Choosing the right pressure washer isn’t a walk in the park though. Your needs might be different from your neighbors so it’s not advisable to buy a similar cleaning equipment like the one he bought. You need to be mindful of something called PSI.

PSI or pounds per square inch is a unit of measure used to quantify the concentration of pressure on an area. The higher the PSI of the pressure washer the more powerful it is at cleaning and removing dirt from your driveway. However, it’s not advisable to get equipment that has really high PSI. Not only will they be harder to operate, it’s also possible to hurt others when you accidentally direct the stream of water on their face or exposed skin.

What Are Your Options

Another reason why it’s hard to choose the right cleaning equipment is the fact that there are hundreds of options with varying PSI available.

1500 PSI

Pressure washers with this low of a PSI are best for use in small areas in your home. You will seldom find one that’s gas powered and their engines aren’t really that big. With a smaller engine you can expect a smaller form factor that’s easy to carry around. A good example would be the AR118 Hand Carry Electric Pressure Washer.

2000 PSI

These units are heavier than the 1500 PSIand could either come with electric or gas-powered engines. You will get to cover more area with one and they’re really ideal for stains or dirt that would usually take time to clean. These are also heavier to carry and more expensive than their 1500 PSI brethren. An example of this would be the Sun Joe SPX3000.

2500 PSI – 2700 PSI

There’s not much difference between 2500 PSI and 2700 PSI. Generally speaking, these are best for residential use. You will have to make sure that you have gas though because you will never find one that has an electric engine. A great washer with this specification would be the Generac 6022/5989.

3000 PSI – 4000 PSI

Models in this range and up are primarily used for either residential or industrial clean-ups. In terms of price, they’re more costly since their engines either run on diesel or gas. However, when it comes to cleaning dirt and grime, you will be able to save a lot of time and in the long run, money as well. For the 3000 PSI variety, you will do no wrong with the Simpson MegaShot MSH3125. On the other hand, if you’re after something that can output at 4000 PSI, the Pressure Pro E4040HC might just be what you’re looking for.

5000 PSI

Most of the washers that could output more than 4000 PSI are generally considered for heavy duty industrial usage. Additionally, with the astronomical cost of these washers you’d be better off contacting your local curb or driveway cleaner.

Choosing Betweena 4000 PSI anda 3000 PSI Pressure Washer

Deciding which of the two you will need to get is really a no-brainer. A washer that can output water at 4000 PSI is around three to four times as costly as one that could output at 3000 PSI. If you’re going to be using it for your home or small office, then going for the one that has a higher output is simply overkill.

The Simpson MegaShot MSH3125 (3000 PSI) costs around $ 400-500.00. In contrast, the Pressure E4040HC Heavy Duty Professional (4000 PSI) is nearly thrice as expensive at $ 1,391.98. The difference in performance for residential clean-ups is really minimal so the Simpson MegaShot has a better price to performance ratio than the Pressure E4040HC.

Now Is The Time to Act

It’s time you took matters into your own hands. With a 3000 PSI pressure washer you can wash away all that grime, dirt, and whatever tough stain you will find inside and outside your home. The Simpson Megashot MSH3125 is the ideal washer to help you with this kind of job.

Invest in one now. You’re not only going to save yourself a lot of effort, you can also expect to have more time with your family and money on your bank account. This is a great opportunity, so make sure you make the most of it by getting this deal right now.

A pressure washer is a highly-pressurized mechanical sprayer that you can use for many outdoor cleaning applications. This includes removing paint, dust, and dirt from all kinds of surfaces such as vehicles, ironworks, concrete walls, and many more. Most of them have various attachments designed for specific use. Many electric power washers can be used for both indoors and outdoors. Some models come with a tank while there are those you still need to attach to water supply. In some cases, hot water is used for easier removal of wall graffiti, or to clean vandalized area.


Electric Pressure Washer vs Gas Pressure Washer

There are basically two kinds of them – electric and gas-powered. Electric ones are considerably lighter and quieter than gas-powered ones, and are usually used in smaller cleaning projects. Some people might advise you not to use an extension cord, which is wrong. The truth is that you should not just use any extension cord. Longer extension cords have higher resistance, which can cause it to run slower. You should also use a heavy duty gauge (thicker) extension cord and with a three-wire connection.

On the other hand, a gas pressure washer provides more power and therefore ideal for medium- to extra-heavy-duty cleaning activities. A major advantage of it is that you can use it anywhere without worrying about power source. But besides most models are heavy and can be noisy, there are cases you might find them difficult to start. A gas pressure washer with an electric starter is more convenient to use as compared to a unit that uses manual pull-start. But it does not mean those with electric starter are always better, as some of them can easily malfunction and not repairable.

Some Important Safety Tips

Aside from reading the safety instructions provided by the manufacturer and following them religiously, there are also other safety precautions you need to follow. Below are some of them:

  • It is always better to test wash a small area first before you proceed to mass spraying.
  • Always wear the appropriate safety footwear, eye and hearing protection gadgets. It is also better if you wear loose clothes.
  • Maintain a good balance and hold the spray firmly during operation.
  • Never use it near any electrical equipment, electrical meters, or any source of electricity.
  • Never allow children to use one.
  • Never leave a running one unattended.
  • Never point the nozzle sprayer at any person or animals, even if it is not in use. It could accidentally discharge water.
  • Its engine can be hot over time. Avoid touching and getting near to it.
  • To prevent electric shock, use a power cord that has a built-in ground fault circuit interrupter (GFCl).

Water Pressure (PSI) Selection Guide

Water pressure is measured at PSI (Pounds per Square Inch). The usual range of water pressure is 1,000- 4,000 PSI. To help you choose the right pressure to use, below are the different classifications of cleaning activities, along with the recommended PSI output:

  • Light Duty (2,000 PSI maximum): Cleaning cars, trucks, furniture, driveways, garage, floors, fences, and sidewalks
  • Medium Duty (2,000-3,000 PSI): Same as the light duty, but can also be used for removing stains
  • Heavy Duty (3,000-4,000 PSI): Same as the medium duty, except for cars and trucks
  • Extra Heavy Duty (Above 4,000 PSI): Same as the heavy duty, except for patio furniture

For personal or home use, the recommended PSI output is up to 4,000 PSI, depending on what you will clean. For businesses and industries, you can use the heavy duty and the extra heavy dutyones.

How to Buy the Best Pressure Washer

Besides understanding the right PSI output for different cleaning applications, you should know its relationship with GPM (Gallons Per Minute), which refers to volume of water flow in one minute. The higher the PSI and GPM are, the faster you can finish the cleaning, and more efficient. Therefore, the best pressure washer for most of your cleaning needs is the one with a higher horsepower engine. On the other hand, you should also make sure the sound is still tolerable.

The water pump increases the water pressure coming from your water supply, and is therefore considered as the heart of the system. It is driven by the gas engine (or electric motor) at a high speed. The pumps vary on design, specs, and their location or position next to the engine. But no matter how careful you are, it can malfunction over time and should be replaced. So, make sure that correct replacement pumps are readily available for your model.

Other factors you should also consider include the weight, spray nozzle types, stability during operation, accessories that could help cleaning faster, and the price as well. To help you find the best pressure washer, here are three of the most popular ones in the market today:

The Karcher K 3.540 X-Series is only one of the proud products of Karcher. Released in 2011, its 1,800 PSI water pressure output makes it ideal for all kinds of house cleaning jobs. This Karcher K3.540 features a patented water-cooled induction motor designed for superior and long lasting performance. This comes along with the 1.5-GPM N-Cor water pump. Connecting your equipment with your water supply is so fast, thanks to the quick-connect system. It is also lightweight at 27 pounds, and therefore very easy to move and transport.

There is also a DirtBlaster Spray Wand to add more water pressure. For safety purposes, the trigger gun of this Karcher K 3.540 has a child-safety lock. The price is just fine for the features. The only negative aspect you might notice is that the attachments are made from plastic, which means they are not of the best quality. You can easily replace them, but of course, that would be extra cost on your part.

Simpson PS4240-S PowerShot Gas Pressure Washer Review

The Simpson PS4240-S PowerShot is designed for professionals and contractors who are into wood restoration, paint preparation, graffiti removal and other deep cleaning services. Equipped with the Honda GX390 OHV commercial series engine that starts smoothly, this powerful Simpson model delivers a whooping 4,000 PSI water pressure at 4 GPM. Being a 13-HP machine that you can expect to be noisy, the additional 50-foot braided steel hose helps keep the noise away, as well as the fumes. The quick connector system makes the installation faster and easier.

This unit weighs 150 pounds when loaded, which is pretty heavy, but the 13-inch premium pneumatic tires make it easier to move. The package comes with 5 stainless steel nozzle tips: 0, 15, 25, 40 degrees, and a soap applicator. Built with a welded steel frame, Simpson PS4240-S features a removable and adjustable unloader and a spray gun with a safety lock to prevent accidents. If there is a disadvantage, that would be the price. But then, the features and quality are more than enough to say that this equipment is worth every penny. In addition, you are protected under a 1-year limited warranty.

Generac 6596 Gas Pressure Washer Reviews

The Generac 6596 can be considered as one of the cheapest gas-powered pressure washers in the market today, but does not sacrifice the quality of performance. Equipped with the 196cc OHV engine, Generac 6596 delivers 2,800 PSI of water pressure at 2.5 GPM. The ergonomic spray gun provides comfort, which comes along with 4stainless steel nozzle tips: 0, 25, 40 degrees, and a soap applicator. However, the 25-feet PVC hose might be quite short for some cleaning activities. Nonetheless, connection is very easy, no need to kneel down.

The 61.5-pound weight is just fine for a machine like this. The engine and the axial cam pump are both positioned in a balance manner, and are well-supported by the set of 10-inch wheels. Setting up the machine is pretty easy, as well as starting it up. However, one major concern is the location of the hot exhaust port, which is on the upper right section of the machine and quite unsafe for users. Apparently, this is also where the hose rests and therefore can easily get burned. But other than that, this Generac 6596 is a great money-saver and worth recommending to any household.
