Zoom on the Sun Joe SPX4600

The Sun Joe SPX4600, a heavy duty pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:

  • pinpoint spot cleaning of hard, unpainted surfaces, accessing high areas, and successfully removing stubborn stains
  • general cleaning of hard surfaces , washing vehicles, and preparing surfaces for painting

  • applying detergents and cleaning agents, and rinsing off 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 SPX4600 in use

The Sun Joe SPX4600

With a 14.5-amp induction motor, its axial pump delivers a pressure of 3000 PSI (roughly 50 times more than a standard garden hose) and a flow of up to 1.3 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 2300 PSI and the flow rate is 1.1 GPM, resulting in the Sun Joe SPX4600's cleaning power of 2530 Cleaning Units.

Being an electric unit, the SPX4600 easily starts up with the press of an ON/OFF switch, providing seamless operation. 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 D23.5 x W18.5 x H35.4 in, the Sun Joe SPX4600 provides great mobility. 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 SPX4600 convenience of transport, while offering a comfortable grip.

With a weight of 36.6 lbs, the unit is comfortably maneuverable for most users, allowing for efficient handling during cleaning tasks. Its motor and metal frame account for a good chunk of that weight. Nevertheless, the SPX4600's two 9.4" wheels ensure it remains easy to maneuver.

Main Features

The Sun Joe SPX4600

The Sun Joe SPX4600's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.

  • Soap injection: Detergent is stored in a 1 gal tank. The detergent dilution ratio can be manually selected, using a dial. Connection of a soap nozzle triggers the pressure washer to automatically incorporate the detergent into the water stream.
  • Pressure hose: For easy organization, the included 20 ft ⌀1/4" high-pressure hose can be stored on the unit using a set of convenient hooks when it's not in use, ensuring a clutter-free workspace.
  • Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
  • Nozzles: Refer to the table below for details on the 5 included nozzles and their recommended surface applications.

The Sun Joe SPX4600's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Sun Joe SPX4600 compare to similarly priced pressure washers.

  • Equipped to deliver up to 3000 PSI, the Sun Joe SPX4600 is recognized as one of the electric models delivering higher-than-average water pressure, priced between $300 and $400. For those prioritizing maximum water stream power, consider the Westinghouse WPX3400e, boasting 3400 PSI, as a standout performer in this price range.
  • In the aforementioned price range, this washer, with 1.3 GPM (gallons per minute), is placed on the lower end of the GPM scale.

  • With a total of 2530 Cleaning Units, the SPX4600 places itself within the average cleaning efficiency range for comparably priced electric units. If the highest overall cleaning power is a priority, the Westinghouse WPX3400e and its 3300 Cleaning Units are notable for their higher potential cleaning efficiency compared to units in the same price range.
