When it comes to pressure washers they can be divided up into two main types – electric powered and gas engine powered. Electric models are cheaper and considered light duty suitable for residential jobs. Gas models have more cleaning power and may be designed for residential or industrial applications. They are much more expensive and require fuel to operate, but are also more portable and great on job sites.
They can also be divided up into categories ranging from light duty to extra heavy duty based on how much pressure they output in terms of PSI (pounds per square inch). (See chart at the bottom of this page for the proper application for different cleaning jobs). In addition to PSI, the other important spec to look for is GPM which is the gallons of water per minute a sprayer uses. You can then calculate the total cleaning power by multiplying PSI by the GPM.
While prices range from about $100 up to well over $1000, for this article we focused on models designed for residential use that cost less than $500. We selected the top 5 best electric and gas pressure washers. See our reviews on each and their specs below.
Our choice for the best electric pressure washer is the Sun Joe SPX3000. It is the highest rated electric version on Amazon. One unique feature that you cannot always find on other models is the two on-board detergent tanks which lets you switch between detergents to easily blast away dirt, grease, and grime. It also comes with 5 different nozzles, a 20 foot high pressure hose and a 35 foot power cord.
The AR Blue Clean AE383 is the best selling electric pressure washer on Amazon. It does not have quite the cleaning power of the Sun Joe, but it is about $50 cheaper and comes with a hose real that keeps the 20 foot hose wound up and out of the way.
The Karcher K 5.540 X Series is the most expensive electric version on our list. The one thing that sets this model apart is the water cooled motor which is designed to last 5 times longer than average. It comes with a 25 foot hose, two spray wands, hose reel, and on-board detergent tank.
The Powerworks 51102 does not have the most cleaning power, but it does have a lot of nice features starting with its design. It sits along the ground instead of sitting upright which makes it almost impossible to tip over. It also has two soap tanks, 30 foot power cord, and 25 foot hose with real.
The Campbell Hausefeld PW1825 is the cheapest and lightest pressure washer to make our list. It weighs in at just 25 pounds and has an on-board detergent tank. It also comes with a 35 foot power cord and a 20 foot high pressure hose, but it does not include a hose real.
Generac 6602 OneWash 4-In-1 PowerDial 3,100 PSI 2.8 GPM 212cc OHV Gas Powered Residential Pressure Washer
The number one choice for the best gas powered pressure washer is the Generac 6602. We love it for its ease of use with the Powerdial variable pressure control which lets you adjust the pressure for whatever project you are tackling. It has 11 inch wheels which makes it easy to maneuver and stay balanced regardless of the terrain. Other features include detergent tank, 3 cleaning nozzles, 30 foot hose and folding handle for more compact storage.
One good selling point of the Simpson MSH3125-S Megashot is its reliable Honda engine that you know will not let you down. This thing is also well built and rugged with 10-inch tires. Other features include 5 quick connect nozzles tips, 25 foot high pressure kink resistant hose, and on-board accessory storage.
The Generac 6022 is a medium sized residential grade gas power washer with just a bit less cleaning power than the first two options on our list. It comes with 4 quick attach nozzles tips and 25 foot hose.
With a price of less than $300 the lowest priced gas-powered pressure sprayer on our list is the Generace 6596. It is also one of the highest rated models available on Amazon which makes it a great value. It also includes 4 nozzle tips and 25 foot hose.
The Karcher Performance Series G2700DH is another model that comes with a Honda gas engine. At 58 pounds it is the lightest gas version on our list. It has a nice top storage area which can store the 5 nozzles and your supplies and detergents. It also has a detergent siphoning system to use your preferred detergent direct from the bottle.
