Highly Powered Pressure washer

This gas pressure washer provides a highly powered flow that will handle most jobs. The 3300 PSI is incredibly powerful and it is backed by a 2.5 GPM. I like the fact it comes with 5 nozzles (0, 15, 25, 40 degree & soap) and its large tires make it easy to move around.

In addition, one can look for some of the features mentioned below that are available in some of the latest models and increase your cleaning efficiency and operatability of power washers.

The Different Types Of Pressure Washers

Cold Water V/s Hot Water Pressure Washer

This is the easiest distinction to make as cold water pressure washers are more commonly in practice among the domestic users and partially for commerical usage as well for certain tasks. Hot water power washers are specifically used for industrial purposes or at surface which have high exposure to more stubborn stains caused by oil or greasing. No wonders they are priced dearlly compared to cold water washers and are more thorough with deep cleaning abillities, as they can work with water temperatures from 140 degrees to 311 degrees Fahrenheit which can even sanitize the surface by killing germs and bacteria too. Another advantage to its benefit is that the drying of the surfaces happens much faster due to higher evaporation. But you need to be extra cautious while working with hot water washers.

What Makes Electric Pressure Washers So Powerful?

The ability to clean up the toughest of grime, dirt, grease and moss stains at quickest of the pace with limited water requirement is what makes pressure washers appear so powerful. The portability and the lightweight of these machines further adds to the charm of working with them.

Electric models come with power as high as 3500 PSI which is sometimes even higher than some of the gas-operated ones, which is quite a proof on how much thrust they can generate. Nevertheless, their portability, light weightedness, and comparative efficiency to complete jobs make high pressure power washers a preferred choice for professionals as well as domestic users.

A few other reasons for them being so popular among users is that they are low-maintenance, are easy to assemble and use, have adjustable water spray nozzles, and have pumps that stop as soon as the trigger is released. Gas-powered power pumps don’t offer the kind of maneuverability and ease of operation & portability as the electric pressure washers have.

What Is A Good Psi For A Pressure Washer?

Power cleaners or Jet Washers are one of the most powerful ways of removing staining, dirt, grime, and other hardened substances that comprise the sheen of objects, surfaces, roofs, siding and automobiles with or without the use of detergents and chemicals. Essentially there are two basic ways to judge the cleaning power of a power washer.


Pounds Per Square Inch

PSI in Pressure washers denote Pounds Per Square Inch of the area that the machines are capable of thrusting.

It is the way that the experts measure a basic unit of pressure. In short, one PSI equals the amount of force that one pound of matter exerts on the earth’s gravity on a one-square-inch area. The higher the PSI count, the more pressure the power washer can withstand and the more forceful the cleaning ability is.

In addition to pressure washers, PSI is also used to measure things such as tire pressure in vehicles, the pressure of various types of gasses, and fluid pressure if you’re in an industrial setting. The PSI is a good indicator of the overall power of the pressure washer; of course, many of the washers with low PSI numbers do an excellent job of cleaning decks and driveways.

Flow Rate Or GPM

It’s often displayed in the amount of water in gallons per minute and refers to the strength of spray by the amount of water a machine can thrust per minute.

It essentially measures the amount of water that is coming out of the pressure washer. If you want to know the total cleaning power of pressure washer, all you have to do is multiply the PSI by the GPM. Just as with the PSI, the GPM should not be your only consideration when choosing a high-quality pressure washer, in part because some very high-power pressure washers can actually damage the surface of the structure that you’re attempting to clean. Many cleaning jobs will recommend pressure washers with certain PSIs and GPMs so if you pay attention to the directions on the package, this should never be a problem.

Some Other Prominent Features To Check For!!


It remains the central feature for most Pressure Washers either gas or electric. Electric models are mostly 2 wheeled or are too light to carry where as gas washers may even come with 4 wheels if you go for a heavier one. You must give ample consideration to this aspect.

Automatic Shut-Off

Though its a very common feature on washers these days, but still be sure with the model you’re buying. You can save a lot of energy with an pressure automatic shut-off facility. It even help maintain the pump and can reduce the risk of undue wear and tear.

On-Board Storage

Do check for the storage features, if a washer provides for cords reels/hose reel, this feature could be a real help. You must also check for provisions for wands, nozzles, detergent bottles as well as these things help in easy operation a lot.


Do check for your work environment, if your work require to operate outdoors, gas washers is for you but otherwise Electric washers are more user-friendly as they make less noise, require fewer safety gears for operation.

Soap Dispenser

The cleaning process can be streamlined easily if automatic pressure washer soap dispenser. Dispensing the soap manually is really time-consuming sometimes. A soap dispenser is extremely useful.

Easy Handling & Operation

Electric power washers hold an upper hand on their gas counterparts for their ease of use. They don’t require much for handling and operation. Anyone with a basic understanding of using machines can learn to use them on a simple plug and play principle.

Usual Accessories With Electric Pressure Washers

Nozzles AttachmentsDetergent SystemCouplingsWandHose & Electrical CordHose Reel

Nozzles Attachments

Pressure washers can produce a high stream of water for providing excellent cleaning. A nozzle is a kind of an attachment which results in more perfect output for cleaning those areas where your hand or normal water pressure is unable to reach.

Nozzles, tips or spray heads are common attachments. The right type of nozzle should be selected as an attachment for cleaning, as a pressure washer follows a single pattern to spray. The wrong attachment might lead to breaking or damaging the delicate objects if more than the required pressure is exerted. Pressure washers are much more effective with the right nozzle attachment.

Many types of nozzle attachments are available in the market these days, which have different colors and different spray patterns (15-degree, 40-degree, 65 degrees, etc.). So, choose the correct one for the best results.

Detergent System

If we want a very effective cleaning performance then detergent builders are the right choice. These detergent builders help in binding cations, like calcium (Ca2+) and magnesium (Mg2+) for best results. They mainly act in enhancing the quality of water making it softer. Two types of detergent builders are available in the market these days: organic and inorganic.

These are multifunctional and one or more than one is included in a detergent, which enables it to develop into a powerful detergent system. Detergents comprise surfactants and chelating agents. These builders help in increasing and improving the detergent efficiency.


Couplings mean to work in making a proper connection between two shafts for accurate transmission. This can also be called a joint. It has varied functions to perform like transmitting power, absorbing misalignment, absorbing vibrations to protect the surroundings. It also helps in preventing the heat transfer to the driven side.

It is a small connection but has many roles to play, from accurately conveying the power of the machine to absorbing the mounting errors in the axis of the machine. Couplings are of many types, which helps in providing rigidity, vibration absorption, higher precision, and higher flexibility. A proper coupling with the right type of features should be selected for the best output.

The Wand

Any long and thick stick which is supposed to perform tasks of varied types. For e.g. a magic stick is called a magic wand. Traditionally, wands were made up of wood, but these days there are metal or plastic wands also. Some wands are specially designed for electric pressure washers. A wand that is perfect for your needs should be selected.

Wands are used for gas pressure washers and electric pressure washers, though designed differently for both.

Usually, the wands which are designed for electric pressure washers are made of plastic and provide easy connectivity. Wands work as an effective attachment for different tasks. Read more

The Hose And Electrical Cord

The hose is a tube, can be termed in simple words as a pipe that is used for transferring fluids. It comes in different materials such as rubber, plastic, stainless steel, PTFE (Teflon), etc. The hose and electric cords which are designed for electric power washers help and facilitate in delivering reliable electric power.

These cords work in making proper connections from one end to the other for the proper functioning of any machine. The quality cords are very beneficial and potent for any machine. Read more

Hose Reel

The hose reel is usually cylindrical in shape and helps in storing a hose. It is like a spindle that is made up of plastic, fiberglass or metal. They are usually spring / motor-driven or a hand crank. If the hoses are not stored properly, then there might be chances of tangling of hose or they might get unruly.

It can be dangerous as anyone can trip and get hurt. The working efficiency increases a lot with the help of these reels. Even the unused cord can be kept off the ground in a proper manner. A hose reel is a perfect way to manage the cord along with increasing the overall efficiency of the power tools.
