The Best Gas Pressure Washers This Year: Buying Guide & Best Product Reviews

Recommended Posts

Though small-scale cleaning jobs can be handled by a good vacuum cleaner or even a combo as rudimentary as bleach and mop, for heavy cleaning works your best bet would be a best rated pressure washer. When faced against a beam of high-pressure water jet, even the most stubborn stains and dirt splotches would be quickly erased.


In this best pressure washers reviews, we’ll show you some of the best gas pressure washers on the market. As the strongest kind of pressure washer there is, we’re certain they will satisfy if you need maximum cleansing power.


What Is a Gas Pressure Washer and Why Choose One?


A gas pressure washer uses a gas-firing motor to pressurize water. It is different from an electric pressure washer, which uses electrical power, instead.


Because gas motors can generate significantly more power than electric, gas pressure washers are the most powerful type of washer you can possibly buy. The majority of the top rated pressure washers that are used for industrial purposes (scrubbing metal, paint-stripping, etc.) are gas-fired.


And that is also the greatest offering gas-powered pressure washers can offer to their users: raw cleaning power. If you want a heavy duty washer that can handle intensive cleaning jobs like multi-story home cleaning, washing the patio, fences etc., a gas-firing washer would be perfect.


What to Look for in a Highest Rated Pressure Washer?




Just like everything else, not all gas pressure washers are created equal. The power output of one model from one brand may differ from another. Therefore, when you’re shopping for a new washer, make sure to read carefully into the product’s description to see if its power can meet up with your needs.


There are three numbers you ought to focus on: Pound per Square Inch (PSI), Gallons Per Minute (GPM), and some models even list Cleaning Unit (CU).


The PSI number indicates the maximum water pressure your washer can generate. GPM will tell you the maximum flow rate. Lastly, CU— the multiplication of


PSI with GPM— will tell you the overall performance of the washer. CU is the most telling calculation of a washer’s performance compared to others. You should always focus on this number if the manufacturer wrote it out for you. Unfortunately, not all choose to do that.




Portability is absolutely crucial. Because a gas washer can weigh dozens of pounds easily, a good pressure washer for the money should have features to make it easier to transport. Usually, the gas motor is mounted on a steel frame, which in turn sits on top of a pair of wheels. The wheels will make it significantly easier for you to cart it around.


The Best Gas Pressure Washer to Buy in 2020

This rating puts it in the light duty class: it won’t be able to handle tough jobs like multi-story home washing or paint stripping, but it will do the job for cleaning out gunks and dirt splotches around the house.
