Power

The Sun Joe SPX4003-ULT in use

The Sun Joe SPX4003-ULT

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. While these PSI and GPM values represent the maximum capabilities of the washer under specific conditions, it's important to note that under typical usage, the working pressure is 1650 PSI and the flow rate is 1.1 GPM, resulting in the Sun Joe SPX4003-ULT's cleaning power of 1815 Cleaning Units.

As an electric pressure washer, the SPX4003-ULT's motor is effortlessly activated with a simple ON/OFF switch, ensuring convenient operation. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.

Design & Handling

Enhanced mobility is a key feature of the Sun Joe SPX4003-ULT, thanks to its hand truck design. The sturdy metal frame ensures the longevity of the assembly, offering stability and protection for internal components, even during rigorous use. The foam-padded fixed handle adds to the SPX4003-ULT convenience of transport, while offering a comfortable grip.

With its featherlight weight of 31 lbs, this unit offers unparalleled ease of transport and handling. As if its lightweight construction wasn't convenient enough, the unit is equipped with two 8" wheels, adding further ease to its transportation and maneuverability.

Main Features

Along with the Sun Joe SPX4003-ULT itself, the package also includes a spray gun, a wand, a pressure hose and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: Detergent storage is facilitated by the inclusion of a removable 0.42 gal tank. The device has a dial which allows you 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: When not in use, the unit allows for tidy storage of the included 20 ft high-pressure hose using a set of convenient hooks, ensuring convenient organization.
  • 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.
