Zoom on the Sun Joe SPX4600

In a nutshell, the Sun Joe SPX4600 is a heavy duty pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:

  • spot cleaning of hard, unpainted surfaces or high reach areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and frail surfaces
  • applying 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

The Sun Joe SPX4600 in use

The Sun Joe SPX4600

Its axial pump, which utilizes a 14.5 amp induction motor, may deliver a pressure of up to 3000 PSI (almost 50 times more than a standard garden hose) and a flow of up to 1.3 GPM. These are the maximum values that the washer can reach only under specific conditions. Under typical load, working pressure is 2300 PSI and rated flow is 1.1 GPM. These values correspond to a cleaning power of 2530 Cleaning Units.

Being an electric pressure washer, the Sun Joe SPX4600's motor can be easily started by a convenient 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 SPX4600 offers great mobility. The robust metal frame guarantees longevity of the assembly. The foam-padded fixed handle adds to the SPX4600 convenience of transport, while offering a comfortable grip.

The unit can be very easily carried around, as it weighs just 36.6 lbs. On top of its light weight, the transportability and ease of use of this model is further improved by the addition of two 9.4" wheels.

Main Features

The Sun Joe SPX4600

Along with the Sun Joe SPX4600 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.

  • 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.
