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. These are the maximum values that the washer can reach only under specific conditions. Under typical load, working pressure is 1600 PSI and rated flow is 1.1 GPM, resulting in the Sun Joe SPX4003's cleaning power of 1760 Cleaning Units.

The SPX4003 is an electric pressure washer and thus, can be easily started by an 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 offers superb mobility, with a hand truck design and approximate dimensions of D21 x W19 x H37 in. Its sturdy metal frame provides longevity to the assembly. The foam-padded fixed handle adds to the SPX4003 convenience of transport, while offering a comfortable grip.

Because the device weighs just 27.3 lbs, carrying it around is very easy. As if this lightweight wasn't enough, the device also features two 8" wheels to further improve its ease of use and of transport.

Main Features

The Sun Joe SPX4003's package includes a spray gun, a wand, a pressure hose and a detergent injection feature, with a more detailed description below.

  • Soap injection: A safe detergent storage is facilitated by a removable 0.42 gal tank. The detergent dilution ratio can be manually selected, using a dial. 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 included 20 ft high-pressure hose can be neatly stored on the unit when idle thanks to a set of convenient hooks.
  • Spray gun and wand: Both the classic ergonomic spray gun and its versatile wand may be conveniently 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.
