How to Choose a Power Washer

If you are reading this, you are likely in the market for a pressure washer or power washer. A quick search online will reveal many different options available, which may leave you feeling a little overwhelmed. How do you know which option is best for you and your lifestyle? To make that decision, there are a few specific factors to consider.

Gas or Electric

One of the biggest choices is whether you want a gas or electric pressure washer. Each of these options comes with benefits as well as weaknesses to consider. There is no one-size-fits-all best option. Instead, look at which will best fit your needs.

For most people, an electric washer will offer enough power for their basic tasks. They are designed for smaller jobs and are generally lower power than the gas alternatives. Electric washers run quieter, without the excess noise created by gas washers, and require less maintenance.

If you are planning on larger cleaning projects, electric washers are known for getting hot and even overheating. It is where a gas washer is often preferred. The gas engine provides these washers with more power to break down tough stains and messes. It also gives the ability to run for longer periods without any complications. These are often used when cleaning heavy equipment such as farm or construction machinery.

Maximum Water Pressure: Pounds per Square Inch (PSI)

The maximum water pressure (PSI) refers to the force of the water coming from the washer. The higher the PSI, the stronger the flow of water. It allows it to tackle tough stains and heavy-duty cleaning projects. It isn’t to say that every buyer should seek out the highest PSI. Take a moment to take stock of the jobs that you are planning to complete with your washer. For smaller, more detailed jobs, a lower PSI washer may be a better fit.

Maximum Flow Rate: Gallons per Minute (GPM)

Similar to the PSI, the maximum flow rate is a way of measuring the power of a washer. In this case, it refers to water that moves through the washer during use. A power washer with a higher GPM is designed to clean faster and more effectively by powering your cleaning efforts with more water moving through the high-pressure hose and nozzle. Alternatively, a lower GPM, much like a lower PSI, is a better fit for a smaller and more delicate job.

For the most part, PSI and GPM are directly correlated. However, there is some variation to consider when shopping. Depending on the water source that you have available, you may not be able to support the highest GPM machines. In this case, it would be important to select something that runs at a slightly lower flow rate.

Portability

While almost all power washers can be moved as needed to different projects, there is no denying that some are far easier to move than others. If you want to purchase a washer to clean vehicles, you don’t need lots of portability. Smaller, lightweight machines often offer a lower PSI. However, they are easier to transport to different areas. 

If you require a more powerful washer, look at the features associated with portability that they have addressed. Power washers that include a larger fuel tank may appear lower weight until you factor in the weight of the fuel. It may include comfortable hand grips, pneumatic wheels for uneven surfaces, and on-unit storage for parts and accessories.

Water Temperature Controls

The secret to the cleaning abilities of a power washer compared to a basic pressure washer is the temperature. Unlike a pressure washer which relies on the pressure of the water to lift dirt and grime, a power washer combines high-pressure water with steam. It allows lifting stuck-on messes, grease, and set-in stains that a pressure washer can’t remove. 

Many power washers have an ‘on’ and ‘off’ control, turning on the heating element or turning it off. However, if you are looking for more control, some pressure washers allow you to adjust the water temperatures needed for different cleaning tasks.

Additional Features

While the additional features offered by some models may not make or break your choice in a washer, they can offer a better experience when completing certain jobs. For this reason, it’s always a good idea to look at what the different options have to offer as they relate to the tasks that you plan on tackling.

One common selling feature is the inclusion of additional nozzles, allowing you to customize the stream of water to best fit the project at hand. Some washers also include cleaning brushes that attach to the washer for cleaning automotive wheels or other tasks that require scrubbing. A foam cannon will allow you to tackle tougher stands and projects and additional detergent bottles to store and carry different detergent types to plan for multiple projects.

At the end of the day, you want to find the options that best suit your needs, making your job easier while staying within your budget.

How We Picked

In creating this guide, I wanted to ensure that there were options for a wide variety of different uses and lifestyles, ranging from those that are just addressing the most basic household tasks right up to those that may be tackling some heavy-duty cleaning. It meant exploring the features and capabilities of a wide variety of different washers.

After creating a list of the different situations that I wanted to cover, I started looking at the specific capabilities of the many power washers on my list. It included assessing the portability, washing power, engine types, options/features, and overall value. With all of this in mind, I narrowed down my list settling on the top 5 power washers highlighted here.

Our Pick for the Best Overall Power Washer

Selecting the best power washer is largely dependent on the tasks that you are preparing to tackle. Concerning the PSI and GPM of the different options, some users will require the additional power of a high PSI and GPM unit while others may be better suited to the lower cost and lighter weight washers with a lower PSI and GPM. 

Additionally, some tasks need more time and water to complete, requiring a full fuel tank to heat the water appropriately. In short, there is no one-size-fits-all solution, which is why we have highlighted 5 different options here.

However, if we did have to identify one of the five that stood out for most situations, we would select the Mi-T-M HSP-3504-3MGH HSP Hot Water Gasoline Direct Drive Pressure Washer. The gasoline-powered design of this unit gives you full portability without having to concern yourself with the availability of an electrical hookup. It also provides a higher PSI and GPM suitable for tackling the more difficult tasks that you may face.
