Zoom on the Sun Joe SPX4001

  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted or delicate surfaces
  • applying detergent and cleaning solutions

Ahead are presented its power characteristics and design, its main features and any other additional features.

Power

The Sun Joe SPX4001 in use

The Sun Joe SPX4001

Its axial pump, which utilizes a 14.5 amp motor, may deliver a pressure of up to 1450 PSI (almost 24 times more than a standard garden hose) and a flow of up to 1.24 GPM. These values correspond to a cleaning power of 1798 Cleaning Units.

As it is an electric pressure washer, the motor of the SPX4001 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

With its hand truck design and approximate dimensions of D21.2 x W19.3 x H36.6 in, the Sun Joe SPX4001 provides great mobility. The robust and sturdy metal frame offers longevity to the assembly. The foam-padded fixed handle adds to the SPX4001 convenience of transport, while offering a comfortable grip.

Since the unit weighs only 32.4 lbs, it is very easily carried around. A set of two 8" wheels also improves the ease of transport of the device.

Main Features

Along with the Sun Joe SPX4001 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: Detergent is stored in a removable 0.4 gal tank. The unit features a dial to allow you to manually choose the detergent dilution ratio. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • Pressure hose: Using a convenient hose reel, which also improves its lifespan, the included 20 ft ⌀1/4" high-pressure hose can be easily stored on the unit when it is not running.
  • Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
  • Nozzles: The 5 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.
