According to the Sun Joe company, this model is their number one best-seller of all time. It has it all – speed, power and so much more. It is effective on vehicles of all kinds, the walls of houses and other buildings, driveways, lawn furniture and everything in between.
This particular pressure washer's motor is an 1800 watt/14.5 amp electric motor. It has a PSI of 2030 and a GPM of 1.76, which is about standard for any personal (also known as a “consumer”) pressure washer.

Best Uses for Electric Power Washers
Auto Washing
Because a pressure washer has so much more water pressure than a regular garden hose, many people use them to clean their vehicles. In addition to allowing the car to be cleaned faster, a pressure washer is also better for water conservation. It can also clear away some of the tougher stains that a garden hose can't.
Garden/Patio & Accompanying Furniture
If you have a concrete or wooden patio, chances are, it isn't as clean as you'd like it to be. Buying and using a pressure washer can remedy that situation. Outdoor furniture, too, is particularly prone to getting dirty, grimy and even covered with mildew. A pressure washer can also handle these issues. Whether your furniture is wooden, vinyl, plastic or something else, a pressure washer can be used to take years off the appearance of it. Most washers are not recommended for use with glass, however.
Outside of the House and Fences
It doesn't matter if you live in a relatively small house; if you start trying to wash the exterior of your home with a garden hose, it's going to feel like you live in a McMansion. However, with a pressure washer, you'll be able to cut the time in half, and the power behind it is strong enough to remove the most caked-on dirt and seeped-in stains.
Whether your house is made of brick, cinderblocks, wood or something else, an electric pressure washer can clean it right up.
Gear Tip:
Invented by Alfred Karcher in 1950, the first pressure washer combined hot water with an internal combustion motor. It contained a high-pressure water pump and hose and a switch that allowed it to work like a high-powered garden hose.
How to Choose the Right Pressure Washer
The first thing you need to familiarize yourself with when looking to purchase a new pressure washer is the lingo.
Pressure Washer Terms
What do all those acronyms in the specs actually mean? There are three main ones to consider:
GPM: Gallons Per Minute
Put simply, GPM is just how much water is being sprayed from the pressure washer's hose each minute. The higher the GPM, the faster the water sprays the surface of whatever you're cleaning, and the faster you're able to get your project completed. Remember: GPM = Speed.
PSI: Pounds per Square Inch
PSI is a measure of how much water pressure your pressure washer is capable of exerting. When a stain sets on your house, car, etc., a chemical bond is formed between the surface of your item and that stain. The longer the stain sets, the stronger the bond becomes.
For a pressure washer to break that bond and remove the stain, the PSI will have to be pretty powerful. In laymen's terms, the higher the PSI on a pressure washer, the more powerful the blast of water is going to be. Remember: PSI = Power.
CU: Cleaning Units
CU is the actual amount of surface area your pressure washer can clean in a given amount of time. CU is calculated my multiplying your GPM (speed) by your PSI (power). The higher the total CU, the better your pressure washer is going to work.
With those things in mind, we've compiled a list of the top 11 best (in no particular order) pressure washer finds on Amazon to help you narrow down your search.
Conclusion
With this buyer's guide, you can now be assured that you have gained a lot of important information about these high-pressure washers. The toughest part of your entire search will be to narrow down your options.
