Sun Joe SPX4000 PRO pressure washer review

Whenever we talk about the best electric power washers, then Sun Joe is one of the most trusted names, because they have a well-reputed name in engineering such decent quality pressure washers. And according to so many electric pressure washer reviews, the Sun Joe SPX4000 is rated as the best electric pressure washer 2019.

Packed with 1800 watts of pure power, the 14.5-amp motor generates up to 2030 PSI to demolish every last bit of dirt. Five Quick-Connect tips allow you to go from intense jet to gentle spray to suit the cleaning task, and the onboard 54.1 fl oz detergent tank lets you dial-in just the right amount of detergent to give your cleaning blast a boost! Featuring Sun Joe’s exclusive Pressure-Select Technology, the SPX4000 lets you pick the perfect pressure to combat grime with professional results.

This pressure washer has a 14.5-amp electric motor that uses pressure-select technology. This motor is powerful enough to generate up to 2030 PSI using 1.76 GPM. This provides maximum cleaning power for all your cleaning projects.

However, it is adjustable so that you can choose the power you want. The pressure select technology enables you to choose a low PSI setting of 1450, which works great for most cleaning tasks. The higher setting amps it up to full PSI.

It comes with five quick connect spray tips. This furthers your cleaning customizations. You can choose from 0, 15, 25, 40, and a soap spray tip.

Also included with your purchase, is 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. This means you get everything you need to get started on your outdoor projects.

A bonus for you is that all accessories have a place on the machine so that you can avoid worrying about where you put them the last time you used it.

This pressure washer has a safety lock switch on it. The Total Stop System (TSS) automatically shuts off the pump when you are no longer squeezing the trigger. This prolongs the pump life and saves energy. It is also helpful if you need to stop cleaning because a pet or a child comes too close.

There are several accessories that you can purchase to help your cleaner work more effectively. They include a turbo head nozzle, a rotary wash brush, a deck and patio cleaner, a longer extension lance, and a longer extension hose.

The SPX4000 is very portable, despite the fact it weighs in at 27.8 pounds. It has easy glide wheels so that you can roll it over any surface. It measures 37 x 18 x 22 inches, which means that storage should be easy for most smaller sized sheds.

With a machine this good and at such a price point, there have to be a few drawbacks to it. However, it is quite surprising that the Sun Joe SPX4000 has so few of them which won’t exactly be causing you much trouble. However, just to make sure that you get a good idea of that in which you’re investing your money, we’ll be covering what this specific power washer lacks as well.

  • While the weight of the machine is quite light and the size is quite compact with a broader base, the exterior material is still made of cheaper plastic, making the machine more prone to breaking from a fall or other similar impacts.
  • Continuing upon the last point, even though the machine is smaller than most other power cleaners, it also acts as a drawback for it as it is held down by its size. If it was a little larger, it could’ve doubled up as a commercial power washer in addition to a household power washer. However, in its current state, it is confined to simply cleaning home surfaces. Anything larger than a home, and you’ll start wishing that you had an industrial power washer instead.
  • The uniform pressure hose provided with the machine is only twenty metres in length, making it rather short. It is rather tedious to use when being used outside while plugged inside. There is a garden hose adapter, but it needs a uniform pressure pipe to work.
  • The SPX4000 also lacks the tangle free cord from the SPX3000, making maneuvering the machine just a tid bit more difficult.
  • Furthermore, not running on gasoline means that it cannot be used just anywhere and is heavily reliant on a working power source for usage.
  • Finally, the most concerning drawback of the machine is the fact that it uses proprietary attachments for it. This means that all attachments have to be bought from Sun Joe and you cannot use any other attachments you might have had from previous power washers. While they do have most attachments available, and the machine itself provides you with sufficient attachments, in case you need one and Sun Joe doesn’t sell it, you’re stuck.

Sun Joe SPX4000 PRO pressure washer Test Results

Easy to move and transport. Easy to operate — just plug it in — but may need an adapter for some outlets. Hose less convenient to store than others. Cord is very easy to wrap and store. Wand very easy to remove and use. Very easy to use and read on-off switch. The Total stop Power  saving system helps in saving the energy and also makes the life of pump longer. Overall Recommended.

The Sun Joe SPX4000 is part of the Pressure washer test program. In our lab tests, Pressure washer models like the SPX3000 are rated on multiple criteria, such as those listed below.

Cleaning: Versatility and efficiency in cleaning a range of surfaces. The better performers have multiple spray patterns that can cover various cleaning chores, from light, superficial cleaning to deep cleaning of concrete, decking, and other hard-to-clean surfaces.

Power: A combination of pressure, measured in pounds per square inch (psi), and flow, measured in gallons per minute (gpm). Higher pressure results in better cleaning of a given surface; coupled with a higher flow as well, you’ll get the job done the fastest.

Noise: A combination of measurements, based on dBA, reflecting the proximity of the operator to the pressure washer. While our Noise score averages measurements taken close by the machine and at the end of the hose’s typical reach, we strongly strongly recommend hearing protection for working close by a gas-powered model in particular.
