Zoom on the Sun Joe SPX4501

In a nutshell, the Sun Joe SPX4501 is a medium duty pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:

  • spot cleaning of hard, paint-free surfaces and out-of-reach areas
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and frail surfaces
  • application 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

The Sun Joe SPX4501 in use

The Sun Joe SPX4501

Its axial pump, which utilizes a 13 amp induction motor, may deliver a pressure of up to 2500 PSI (almost 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. These values correspond to a cleaning power of 2200 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.

With a weight of only 45.9 lbs, the unit is definitely easy to carry around. As if this lightweight wasn't enough, the device also features two 9.5" wheels to further improve its ease of use and of transport.
