Note: Sun Joe claims that this unit provides 2500 PSI and 1.48 GPM. In fact, the stated PSI value is only at the initial trigger pull, while the stated GPM value is with a nozzle opened to the lowest pressure. Under a typical load, the working pressure is 2000 PSI and the flow is 1.1 GPM.

Zoom on the Sun Joe SPX4500

The Sun Joe SPX4500, a medium duty pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:

  • spot cleaning of hard, unpainted surfaces or high reach areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and fragile surfaces
  • application of detergent and cleaning solutions

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

Power

Its axial pump, which utilizes a 13 amp motor, may deliver a pressure of up to 2000 PSI (almost 33 times more than a standard garden hose) and a flow of up to 1.1 GPM. These values correspond to a cleaning power of 2200 Cleaning Units.

The SPX4500 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

Thanks to its hand truck design and approximate dimensions of D23.5 x W18.5 x H35.4 in, the Sun Joe SPX4500 offers great mobility. The robust metal frame guarantees longevity of the assembly. The foam-padded fixed handle adds to the SPX4500 convenience of transport, while offering a comfortable grip.

The unit can be very easily carried around, as it weighs just 37 lbs. On top of its light weight, the transportability and easy of use of this model is further improved by the addition of two 9.4" wheels.

Main Features

The Sun Joe SPX4500 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: Detergent is stored in a removable 1 gal tank. The detergent dilution ratio is selected manually, via a dedicated dial. When a soap nozzle is connected, the detergent will be added automatically to the water.
  • Pressure hose: Using a set of convenient hooks, the included 20 ft 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 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
