The Sun Joe SPX4003 is a medium duty pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • 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.

Being an electric pressure washer, the Sun Joe SPX4003's motor can be easily started by a convenient 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 robust metal frame guarantees longevity of the assembly. The foam-padded fixed handle adds to the SPX4003 convenience of transport, while offering a comfortable grip.

Standing at only 27.3 lbs, this model can be carried around very easily. To further improve its transportability and ease of use, the unit also features a set 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 storage is ensured by a removable 0.42 gal tank. The unit features a dial to allow you to manually choose 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: The 20 ft high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
  • Spray gun and wand: The included classic ergonomic spray gun and its versatile wand can be easily stored in a side hook. 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.
