Sun Joe SPX 4000 Review

When it comes to outside cleaning, pressure washers are one the thing I trust the most. Previously, I used to clean using a water hose. It used to get things cleaned, but it was unable to give them new look. Pressure washers can make this tiring work much easier and more fun. You can clean large yards and huge walls in a matter of few minutes. the best part is that it is a one-time investment. You just have got to buy it one time and enjoy using it for years.

Choosing the right pressure washer for your home can be challenging. This is why we have provided you with one of the leading domestic electric pressure washers available in the market. By the end of this article, you will know all the necessary details.


Sun Joe SPX 4000 is an electric pressure washer, which means you do not have to worry about gasoline. It is a small portable unit. It has got everything you are going to need on board. Here are some mentionable features.

Powerful motor

The whole performance of a unit depends on the power of its motor. A powerful motor ensures that you get desired results. It comes with a 14.5-amp electric motor. This motor is powerful enough to generate up to 2030 PSI using 1.76 GPM. With this pressure, you will be able to clean out the toughest stains in a matter of a few minutes. The best part is that the power is adjustable. 

Having adjustable power makes this unit much more versatile and easier to use. Having high pressure is ideal, but not every situation requires excessive pressure. This is why it is important that your machine comes with a setting that lets you adjust the setting according to your environment. You can choose a low PSI setting of 1450. This is the ideal pressure for cleaning around the house. You can set a high PSI setting for getting tough stains like getting tough oil stains from the driveways.

Quick connect spray tips

Like any other standard domestic pressure washer, this unit comes with five quick-connect spray tips. You can choose from 0, 15, 25, 40, and a soap spray tip. These are best for the customization of your unit. The 0 tips is used when excessive water pressure is required. It offers the highest pressure possible, which is why it is important that you make sure that the target is strong enough to bear the pressure. Otherwise, if the target is fragile, you might end up damaging it. For example, if you wash your car with this tip, it will rip the paint off. Then comes the 15 tips, the pressure is slightly lesser than 0 tips, but it’s still strong enough to damage the target. It is perfect for cleaning greasy surfaces. The 25 and 40 tips offer the perfect pressure for cleaning around the house. these are ideal for low-end jobs like cleaning sidewalks or washing your car. But not the least is the detergent spray nozzle. This one is extremely important as well. It is specifically designed for spraying detergent on the target.


This unit has got everything you are going to need. This is some good news, as you do not require to buy anything extra. It comes with an extension wand, a 20ft high-pressure hose, a power cord with GFCI protection, a garden hose adapter, and even a needle clean-out tool. The pressure hose is long enough to reach distant places. Even if you are performing a simple task and the target is right in front of you, it is important that the chord is long enough, and that you are easily able to move around. You will not be needing the extension cord all the time, but even if you do it is easy to attach and detach. You will not be requiring extra tools.

Some units come with pair of extra brushes and cleaners. If you want to get the same effect, you can buy these extra accessories. A turbo head nozzle, a rotary wash brush, a deck and patio cleaner, a longer extension lance, and a long extension hose. Do not worry, it is not necessary to buy these items, to get the desired results. You will be fine with these. These are some extra help for perfectionists. 

Total Stop System (TSS)

Before buying any pressure, the washer makes sure that it has got this feature. it might not seem fundamental at this point, but once you get out there and start using it, you will be needing this. For those who are wondering what this feature is, it is an automatic lock system that is placed on the trigger. Whenever the unit is not in use, it automatically turns off the motor. It is really helpful in keeping the motor safe and makes sure that it does not burn out when the unit is left unattended. It will also increase the life of your unit and saves energy. It is also very important from a safety point of view as well. You can shut off the motor at any given moment in case of an emergency. 

Lightweight and ease of use

Pressure washers are supposed to make things easier for you. If your pressure washer is heavy, it will cause problems for you. for easy and efficient cleaning, it is important that you are able to move around the unit whenever you want. This unit is lightweight, which means it will not be a problem even if you have got to carry it around. It weighs only 27.8 pounds. It comes with wheels as well. So, if carrying it around is not an option for you, you can just pull the handle and easily glide it around like luggage. It is small in size as well. Pressure washers are not something that you are going to use every day. Which means it is going to spend most of its time in the storage closet. It is important that it does not take up all the space. It measures 37 x 18 x 22 inches, which means storing it will not be a problem. For me, the size is just perfect. If the pressure washers are smaller than this one, there are greater chances of them tipping over all the time. This offers stability as well as has a large base size.
