The concept of pressure washers was discovered by accident during the glory days of prohibition in 1926. Frank W. Ofeldt II was in his garage designing a portable whiskey when he discovered the strange phenomenon of his design’s steam. He realized that a cleaning contraption could be made out of it. Ofeldt collaborated with the Homestead Valve Company for a pump casting.

Together with Frederick E. Schuchman Sr., they developed the contraption and named it the “Hypressure Vapor Spray Generator.” It was a man named Mr. Eltinge — also the brother of Julian Eltinge, one of the world’s greatest female impersonators of the 20th century — who suggested they name the apparatus “High-Pressure Jenny.” He received $20 for rights to the name. The name stuck even today as pressure washers are still sometimes known as “high-pressure Jennys” or “steam Jennys.”

There are a number of different reasons why businesses like to make use of hot water pressure washers. Firstly, you should understand that these hot water pressure washers have several advantages over their cold water cousins. The most apparent is that these hot water pressure washers can reach temperatures of up to 311 degrees Fahrenheit. You can clean things much more easily when you have access to water that is this hot.

To give you something to compare it to, your average cold water pressure washer is only capable of reaching temperatures of up to 140 degrees Fahrenheit. This is very close to the temperature that the average water faucet in a home can reach. Using a cold water pressure washer is much safer for this reason but there are situations where you will want to have the incredibly hot water in order to clean something more easily. You just need to be careful with how you are handling this hot water pressure washer.

When you have access to using really hot water, it is going to be much easier to clean things that are caked with oil and grease. You won’t have to worry about not being able to clean these items effectively because the hot water pressure washer is going to cut right through that grime. You won’t even need to use as much detergent when the water is this hot so it can be very convenient to use.

You will also be able to feel confident knowing that the hot water is killing germs and bacteria. If you want to pressure wash your deck to get some mold off of it, then having access to a hot water pressure washer is going to be the most effective thing. It will kill off the mold and can leave you with a nice clean deck to enjoy. People who want to be as cleanly as possible will enjoy the idea of being able to kill off bacteria with the extremely hot water.

Drying times are also significantly faster when you use a hot water pressure washer. The water is so hot that it evaporates more quickly and you won’t have to wait around for things to dry very long. There are many benefits to owning one of these hot water pressure washers but they are a little dangerous to use if you don’t know what you’re doing. You will want to be very careful about how you are using this powerful tool so be mindful of your surroundings and make sure that you’re using it properly.

3. Electric Pressure Washers

Electric pressure washers are probably the most common type of pressure washer that you will see being used at someone’s home. These pressure washers are really convenient to use and are generally pretty lightweight. You will be able to use these pressure washers effectively to take care of any normal home pressure washing needs. If you want to be able to clean off certain things on your property, then this is going to be the most affordable way to do that in many cases.

The average electric pressure washer will cost a little less than a gas-powered unit. This is really appealing to those who want to be able to have access to a pressure washer but don’t want to have to pay out a lot of money for it. Some models can be a little more powerful than others and you may find electric pressure washers with certain desirable features. Regardless, these pressure washers are limited in their power output by the electrical outlet that they are getting their energy from.

Most electrical outlets only allow a certain amount of power to be outputted. In North America, you will find that most outlets are capped out at being able to output 120V. You will typically be outputting this voltage at between 15 and 20 amps. This amount of power will be enough to handle many tasks but it will not be able to hold a candle to the overall power of a gas-powered unit.

Despite this, many people choose to buy electric pressure washers because they see them as the more convenient option. Slightly lower price points combined with not having to deal with the fumes that come from using a gas-powered option are certainly good reasons. You will also be able to enjoy pressure washing your home in a much quieter fashion. Electric pressure washers don’t make much noise at all, making them a lot more pleasant to use than the gas-powered ones.

4. Gas-Powered Pressure Washers

If you are seeking a powerful pressure washer to use for important work, then you will likely want to purchase a gas-powered pressure washer. These pressure washers are going to be significantly more powerful than the electric pressure washers that are more commonly used. If you have a big job that needs to get done in an effective way, then you will have an easier time with a gas-powered unit. There are several other aspects of using a gas-powered pressure washer that will appeal to you as well.

Gas-powered pressure washers are much more portable than their electric cousins. Electric pressure washers need to be plugged into a power outlet in order to function. Gas-powered units are not tethered to a cord of any kind so you can freely roam your property and use then wherever it is that you see fit. This can be a lot more convenient than having to run an extension cord out to your barn or some other part of your property that might not have an electrical outlet.

You will also be able to get things washed in a quicker fashion while using this type of pressure washer. The increased power really does work wonders here. You will be able to make short work of even large jobs when you have a really powerful pressure washer to rely on. This means that you can move on to other tasks more quickly and have your chores done in far less time than you would by using other means.

The problems with gas-powered pressure washers rear their head when you consider the noise and the fumes. All gas-powered machines and devices are going to emit noxious fumes so you won’t be able to use them indoors. Most people use pressure washers for outdoor projects anyways but it is possible to use an electric pressure washer inside of your home. This can be useful for pressure washing your walls but that simply isn’t going to be an option with a gas-powered pressure washer.

Aside from this, the noise can really bother some people. The most powerful gas-powered pressure washers can produce a significant amount of noise and it may bother you if your ears are sensitive. This can really make the act of pressure washing much less enjoyable so you may want to take precautions such as purchasing noise-canceling earmuffs. Regardless of the negatives, owning a gas-powered pressure washer is going to be great for you as it will allow you to effectively clean so many parts of your property in a timely fashion.

B. Styles

Most of the pressure washers that you will find on the market will come with wheels for convenient use. This makes it so that you can move your pressure washer to and from wherever it is needed without it being a hassle. There are some models that have two wheels and others that have four.

Being able to find a pressure washer that is good for doing multiple things is really nice. Sometimes you aren’t going to want to pressure wash something at full power. You might need to use a nozzle that will work better for a lighter workload. Luckily, it is possible to purchase a pressure washer that has interchangeable nozzles.

Having many different nozzles to choose from is going to be really nice. You will be able to choose the appropriate nozzle for a given situation.

4. Adjustable Spray Nozzles

You don’t really have to stop what you’re doing as you can simply adjust the nozzle quickly and return to your task.

Most of these adjustable nozzles have two to three stages of adjustment but there is some variance between different brands.

It will save you a bit of time and keep you on the path towards finishing your pressure washing job.

5. Pressure Selection Technology

As noted above, being able to adjust the pressure on your pressure washer can be even easier to use than interchangeable nozzles. It is possible to purchase a pressure washer that has two different pressure selections that you can select. You can set it on low for a lighter workload or you can set it on high for heavy-duty jobs. This is a really easy way to make sure that you aren’t using too much power when you need a lighter touch.

This is distinct from the adjustable nozzles as you don’t have to fiddle with the nozzle itself to change the power options. You will be able to make use of this innovative technology to quickly and effectively change between modes. You won’t have to stop what you are doing and the transition will feel seamless.

In some ways, this may not have as much nuance as the interchangeable nozzles. It is a lot simpler, though, because you don’t have to stop what you are doing to change out a nozzle. You will simply be able to push a button and set the pressure washer to either high or low. This works swimmingly for most jobs and you will be happy to have such a good feature on your pressure washer.

You will be able to take care of several different cleaning projects without having to change things out and this will save you a whole lot of time.

7. On-Board Storage

Being able to store the power cord for your pressure washer in the unit itself is going to be beneficial. There are some pressure washers that don’t come with convenient power cord storage options. This can create a mess when you are putting it up for the day. No one wants to have to deal with tangled cords and you shouldn’t have to leave your cord looking sloppy every time you go to store it.

Buying the right pressure washer will allow you to store the power cord, the wand, your nozzles, and your detergent bottle right in the pressure washer itself. This makes storing it a whole lot simpler and everything will look nice and clean. When you are ready to use the pressure washer again, you will know that everything is right where you left it the last time. This is a small feature that makes a huge difference in your overall enjoyment of the product.

8. High PSI

If you want to be able to handle the most difficult jobs with your pressure washer, then you should seek out one that has a high PSI rating. If you purchase a gas-powered pressure water with a PSI rating that is greater than 4,000, then you can rest assured that it will be able to handle the toughest jobs. These pressure washers are regularly used for industrial purposes but they can be quite useful for residential use as well.

Depending on the situation, you may not have a need to buy a pressure washer that is this powerful. People use these pressure washers to handle the really tough jobs such as agricultural cleaning. You can remove paint with this pressure washer and you will be able to easily clean your driveway as well. It can be a handy tool to own but you will want to be careful with such a powerful tool.

Buying pressure washers that have high PSI such as this will be more expensive than other options. When you want to have the best possible power out of your pressure washer, it is going to be necessary to pay a little more money. If you have large jobs that need to be taken care of, then this pressure washer is going to prove to be up to the challenge. You will always have a really easy time getting your jobs finished when you use this powerful tool.
