Zoom on the Sun Joe SPX4500

The Sun Joe SPX4500 is a medium duty pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and fragile surfaces
  • use of detergent and cleaning solutions

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

With a 13 amp induction motor, its axial pump delivers a pressure of 2500 PSI (roughly 42 times more than a standard garden hose) and a flow of up to 1.48 GPM. These are the maximum values that the washer can reach only under specific conditions. Under typical load, working pressure is 2000 PSI and rated flow is 1.1 GPM, resulting in the Sun Joe SPX4500's 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

The Sun Joe SPX4500 offers superb mobility, with a hand truck design and approximate dimensions of D23.5 x W18.5 x H35.4 in. The robust and sturdy metal frame offers longevity to 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. A set of two 9.4" wheels also improves the ease of transport of the device.

Main Features

The Sun Joe SPX4500'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 storage is ensured by a removable 1 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: The 20 ft high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
  • Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
  • Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.
