Zoom on the Sun Joe SPX4003

In summary, the Sun Joe SPX4003 is a medium duty pressure washer, that offers an all-around versatile cleaning experience, and also:

  • cleaning of painted or delicate surfaces

The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

Power

The Sun Joe SPX4003 in use

The Sun Joe SPX4003

With a 14.5 amp motor, its axial pump delivers a pressure of 2200 PSI (roughly 37 times more than a standard garden hose) and a flow of up to 1.6 GPM, resulting in the Sun Joe SPX4003's cleaning power of 3520 Cleaning Units.

As it is an electric pressure washer, the motor of the SPX4003 gets easily started by a simple ON/OFF switch. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.

Design & Handling

The Sun Joe SPX4003 is very mobile, due to its hand truck design and approximate dimensions of D21 x W19 x H37 in. The strong metal frame assures assembly longevity. The foam-padded fixed handle adds to the SPX4003 convenience of transport, while offering a comfortable grip.

Since the unit weighs only 27.3 lbs, it is very easily carried around. On top of its light weight, the transportability and easy of use of this model is further improved by the addition of two 8" wheels.

Main Features

The Sun Joe SPX4003 comes with a spray gun, a wand, a pressure hose and a detergent injection feature, which are detailed below.

  • Soap injection: Detergent is stored in a removable 0.42 gal tank. The washer has a dial that allows the user to manually select the detergent dilution ratio. Detergent is automatically added to the water when the unit is set to low pressure mode and to the 'Fan Spray' pattern.
  • Pressure hose: Using a set of convenient hooks, the included 20 ft high-pressure hose can be easily stored on the unit when it is not running.
  • Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its versatile wand. Sun Joe's adjustable wand removes the need for different nozzles. By turning the pressure adjustment knob, it is possible to easily change the water pressure from an intense, 0° jet spray to a gentle, 45° fan spray.

Other Features

  • Total Stop System (TSS): This feature automatically shuts off the pressure washer when the trigger is not engaged, to prolong the pump's lifespan.
  • Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation).
  • Accessories: On top of an owner's manual (opens in a new tab) and the usual documentation to get you swiftly started, the Sun Joe SPX4003 also comes with spray gun, nozzle cleaner, wand, power cord and pressure hose.
