Zoom on the Sun Joe SPX4501

The Sun Joe SPX4501, a medium duty pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:

  • spot cleaning of hard, paint-free surfaces and out-of-reach areas
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and fragile surfaces
  • use of detergent and cleaning solutions

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

Powered by a 13 amp motor, its axial pump can deliver a pressure of 2500 PSI (around 42 times more than a standard garden hose) and a flow of up to 1.48 GPM. Combined, these values mean that the Sun Joe SPX4501 has a cleaning power of 3700 Cleaning Units.

Since it is an electric pressure washer, the motor of the SPX4501 is started simply 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 SPX4501 offers superb mobility, with a hand truck design and approximate dimensions of D23.5 x W18.5 x H35.4 in. The foam-padded fixed handle adds to the SPX4501 convenience of transport, while offering a comfortable grip.

The unit can be very easily carried around, as it weighs just 45.9 lbs. On top of its light weight, the transportability and easy of use of this model is further improved by the addition of two 9.5" wheels.

Main Features

Along with the Sun Joe SPX4501 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 storage is ensured by a removable 1 gal tank. The washer has a dial that allows the user to manually select the detergent dilution ratio. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • Pressure hose: A neat storage for the included 20 ft high-pressure hose is facilitated by a convenient hose reel, which also improves its lifespan.
  • 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.

  • Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation).
  • Accessories: On top of an owner's manual (opens in a new tab) and the usual documentation to get you swiftly started, the Sun Joe SPX4501 also comes with wand, nozzle cleaner, pressure hose, spray gun and power cord.
