Let’s jump in and see how it performs.

Pressure Output

A pressure washer is only as good as the pressure it can develop. Unless it can develop high pressures, it will not be able to get rid of all the dirt and grime. This pressure washer does not disappoint when it comes to the pressure output.

You will get two options to work with depending on your needs. There is a low-pressure setting that pushes pressurized water out at 1450 PSI and a high-pressure setting that releases pressurized water at 2030 PSI. The low-pressure setting is strong enough to be sufficient for most uses. You will only need to switch to the high-pressure setting when tackling the toughest of stains.

Switching between these two modes is quick and easy. Just turn the pressure-select knob and you’ll be able to get the right pressure.


Next, we are going to look at how easy it is to work with this pressure washer. With a weight of only 27.8 pounds, this pressure washer is the lightest in Sun Joe’s SPX line of pressure washers. It also comes with two large wheels that will give you no trouble even if you are pushing it on uneven terrain.

The hose on this pressure washer is 20 feet long and it comes with a long 35-foot power cord. This gives you a lot of freedom when using this machine even if you are far from a power outlet. With that said, it’s important to note that this hose doesn’t come with a hose reel so it will need a bit more time and effort to fold after use.


The first accessory is the onboard 54.1 oz. detergent-tank that will enable you to step things up and boost the blast of high-pressure water. There is a second knob just below the pressure select knob that you can use to dial in the speed that you would like the soap to be sucked in.

This pressure washer also comes with 5 spray tips to control the jet that leaves the nozzle. You can choose from a 0, 15, 25, or 40-degree tip to ensure that you get the perfect spray jet for your current task. The last tip is specially made for spraying soap.

Power Rating

Being an electric device with an electric motor, we can’t afford to overlook the power rating. The motor on the Sun Joe SPX4000 pressure washer is rated at 14.5 amps with a power consumption of 1800 watts. It can push up to 1.76 gallons of water every minute.

Sun Joe SPX4000 vs. Sun Joe SPX3000

Let’s now compare the SPX4000 to its more affordable sibling to find out if it’s worth spending the extra amount on the upgrade. The design of the SPX3000 is different from the SPX4000 in that it is taller and slimmer. The wheels are also quite large so maneuverability is not a problem.

Sun Joe SPX4000 vs. Sun Joe SPX3000

You will also notice that the SPX3000 is a bit more affordable. With that said, it’s important to note that this pressure washer is not necessarily less powerful simply because it is more affordable. It comes with the same 14.5 amp motor that is found in the SPX4000.

The use of the same motor on both these pressure washers means that the SPX3000 is also able to reach a pressure of 2300 PSI pushing 1.76 gallons of water every minute. However, it lacks the option to choose between low and high pressure like it is in the SPX4000.

If you want to use a detergent together with the pressurized water, the SPX3000 comes with two 30.4 oz. onboard detergent tanks that you can use to hold different detergents for cleaning different types of stains.

You also get the same five spray tips that will ensure that you get the exact jet that you need from this machine’s nozzle. Like the SPX4000, the SPX3000 does not come with a hose reel, but it comes with the same 25-foot hose and 35-foot power cord.

Sun Joe SPX3000

Verdict: If you need an affordable pressure washer with two detergent tanks and is powerful enough to get rid of most stains at home, then the SPX3000 will work for you. However, if two detergent tanks are overkill for you but you could appreciate low and high-pressure settings, then the SPX4000 is the right choice for you.

Sun Joe SPX4000 vs. Sun Joe SPX3200

Let’s now compare the SPX4000 to the SPX3200 pressure washer from Sun Joe. The SPX3200 is also based on the same motor used in the SPX4000, but it comes with a unique design. Instead of coming with two wheels like the SPX4000, this pressure washer comes with four wheels.

Sun Joe SPX4000 vs. Sun Joe SPX3200

The use of four wheels drastically improves maneuverability because you can simply pull the hose when you need it to move closer and it will roll along with minimal effort. The front 360-degree plastic casters make it easy to move the pressure washer, but they are not as large as the rear wheels; hence you might have trouble moving it on rough terrains.

Like we mentioned earlier, the SPX3200 uses the same motor in the SPX4000 so it can produce up to 2030 PSI with a maximum water output rate of 1.76 gallons per minute. This pressure washer also has a knob that allows you to choose between high and low-pressure output.

To control the jet of water leaving the nozzle, you also get the same five quick-connect spray tips available in the SPX4000. You also get an onboard detergent tank, but this one is a lower capacity because it can only hold 27 oz.

Sun Joe SPX3200

Verdict: This is the same pressure washer but in a compact and easy-to-move shell. There is no significant difference in performance and you get all the options available in the SPX4000. Choose this pressure washer over the SPX4000 if you will be using it in well-paved areas and you don’t mind the lower capacity detergent tank.

Sun Joe SPX4000 vs. PAXCESS Electric Pressure Washer

Next, we’ll compare the Sun Joe SPX4000 with the PAXCESS electric pressure washer. From a glance, you’ll notice that the PAXCESS pressure washer comes with an onboard hose reel that makes maneuverability and storage easier than in the Sun Joe.

Sun Joe SPX4000 vs. PAXCESS Electric Pressure Washer

The PAXCESS pressure washer also outshines the Sun Joe when it comes to pressure and water output rate. It can push water out at a pressure of 2150 PSI and a rate of 1.85 gallons per minute using the 1800 watt electric motor.

The power cord on the PAXCESS pressure washer is 33 feet, hence two feet shorter than the cord on the Sun Joe pressure washer. They have tried to make up for this by having a 26-foot hose that is one foot longer than the hose in the Sun Joe.

In place of the quick-connect spray tips in the Sun Joe, the PAXCESS comes with a single adjustable nozzle that you simply twist to achieve the desired jet. However, when it comes to the design, the Sun Joe looks tougher and more rugged hence, it appears to be more durable.

PAXCESS Electric Pressure Washer

Verdict: Thanks to the hose reel, higher pressure, and an easy-to-use nozzle, the PAXCESS electric pressure washer appears to bring better value for money than the Sun Joe SPX4000. If, however, you are more concerned with durability in tough terrains, then you are better placed with the Sun Joe.

Sun Joe SPX4000 vs. Sun Joe SPX4001-PRO

Finally, let’s compare the Sun Joe SPX 4000 with its closest sibling in the SPX series from Sun Joe: the Sun Joe SPX 4001. If you place these two pressure washers side by side for comparison, you will be able to see just how close these two are.

Sun Joe SPX4000 vs. Sun Joe SPX4001-PRO

When it comes to pressure, the SPX4001 pressure washer comes with the same motor that is in the SPX4000 hence the performance is tied.

The only difference between these two pressure washers is the hose reel that is available in the SPX4001 and absent in the SPX4001. Other than that, you could argue that if you take the SPX4000 and add a hose reel, you will have made a Sun Joe SPX4001.

Sun Joe SPX4001-PRO

Verdict: The verdict here is simple: if a hose reel is important to you, go for the SPX4001. Otherwise, the SPX4000 will be able to give you the same performance, but you’ll have to manually roll the hose after you have finished cleaning. If rolling the hose is not too much of a bother, then you can save some money with the SPX4000.
