They don’t only make quick work out of otherwise long, tedious hours of manual labor, but it’s also super-fun to use. Plus, your kids will get a kick out of washing your car for you, so that’s a plus.

In this article, we’re going to compare two electric pressure models from Sun Joe, a popular pressure washer manufacturer. The models we will talk about are the SPX3001 and the SPX4001. They’re both versatile enough to clean anything between delicate glass windows and hard paving stones. But between the two, which of these Sun Joe models actually offers better value?

PSI (pounds-per-square-inch) is the unit of measurement which shows the maximum amount of force expelled from the wand nozzle, whereas GPM (gallons-per-minute) indicates how water-efficient the tool is. In general, homeowners should find a pressure washer with enough force to clean a wide range of surfaces while using not that much water. Both the Sun Joe SPX3001 and SPX4001 come with 14.5-amp motors that produce up to 2,030 PSI at 1.76 GPM. Compared to a traditional garden hose, in which you’ll only get around 40 PSI while using up around 24 GPM. In a nutshell, these two machines provide amazing amounts of pressure while using hardly any water at all.

Hose Reel

SPX3001 and SPX4001
One of the largest annoyances of picking up after a pressure washer is storing the hose away safely. It goes without saying, but the longer the pressure hose is, the more trouble you need to go through to ensure that the hose is put away safely. That, of course, was how it was with older models. With the SPX3001 and the SPX4001, you have a handy hose reel located around the handle of each model. No longer will you curse under your breath while attempting to tame a 20-foot long pressure hose; simply turn the reel handle and watch the hose retract to a safe, coiled state.

Quick-Connect Nozzles

Quick-connect nozzles alter how concentrated and how wide-spread the spray of water is. You don’t want to blast your car and home windows with high-pressure pencil-like precision since it could send paint and glass flying everywhere. Both of these Sun Joe pressure washers come with five different quick-connect nozzles that you attach to the end of the wand. They are 0°, 15°, 25°, 40°, and soap nozzles. The soap nozzle is used when drawing soap from the machines’ soap tanks for applying a layer of suds to any surface.

Soap Tank

Cleaning vehicles, decks, and outdoor furniture need a thick layer of bubbly soap to get the job done. In order to dispense soap when using a pressure washer, be sure that you’ve attached the soap nozzle to the wand. After doing so, the SPX3001 will draw soap from the built-in 40.6-fluid-ounce soap tank.

The same goes for the SPX4001, but the difference is the capacity of the soap tank. With this model, you’ll get a slightly larger tank which allows you to work longer without having to refill the soap tank. The soap tank on this unit can hold up to 54.1 fluid-ounces of any soap of your choice.

Conclusion: One of the main differences between these two pressure washer models is how large their respective soap tanks are. At the end of the day, the size of the soap tank doesn’t really matter, but having a large tank means fewer refills. In this case, the SPX4001’s 54.1-fluid-ounce tank is the better option, but it just barely trumps over the SPX3001’s 40.6-fluid-ounce tank.

Pressure Select Technology

Most pressure washer models come with a one-power option that delivers the maximum PSI possible. This means that users have to be aware of which quick-connect nozzle is currently attached to the wand to ensure they’re blasting the right amount of pressurized water that won’t damage any surfaces. The SPX3001 is no exception and comes with no onboard PSI or soap-dispensing adjustment system.

The same cannot be said for the SPX4001. This model comes with Pressure Select Technology on the unit which lets users chose from two cleaning options: 1,450 PSI and high-power 2,030 PSI. You can also adjust how much soap to dispense by using this system.

Conclusion: Pressure select technology gives users the ability to choose how much power to blast on a wide range of surfaces. Normally, adjusting how much pressure to apply is done by attaching different quick-connect nozzles, but with the SPX4001, you can use the 0° nozzle while applying only 1,450 PSI of force.


As you can imagine from the many different pressure washer models out there, there are bound to be differences in shape and design. The SPX3001 looks like a regular pressure washer that many other companies produce. You’d have to check the model number carefully to ensure that you’re getting the SPX3001.

As for the SPX4001, the body is located near the wheels, and the handles extend high up off the ground. The shape is similar to what a walk-behind lawn mower looks like. The good thing is that you won’t have any trouble distinguishing this model from other pressure washer models or lawn mowers.

Conclusion: Pressure washers come in a range of different sizes and shapes. Traditionally, pressure washers are vertically standing machines that you move around on rear-end wheels. The Sun Joe SPX3001 is what a classic pressure washer model looks like, but the SPX4001 is different in the sense that it’s shaped somewhat like a walk-behind lawn mower. This makes the SPX4001 easier to move, but in the end, it all comes down to personal preference.

In all honesty, power- and performance-wise, these two models are almost identical. The one, true differentiating feature is the Pressure Select Technology that comes with the SPX4001 that allows you to adjust how much force to apply when cleaning different surfaces. Normally, you can do this by swapping quick-connect nozzles, but we like the extra insurance that the SPX4001’s Pressure Select Technology offers.

Overall, if we had to recommend getting one of these models, we’d advise going with the SPX4001. Of all the 2,000-plus-PSI models available, the Sun Joe SPX4001 doesn’t come with many bells and whistles, but it’ll get the job done and has the capacity to be used on soft and hard surfaces and anything in between.
