  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • intense cleaning of tough, paintless surfaces
  • cleaning of painted and frail 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

The Sun Joe SPX4001 in use

The Sun Joe SPX4001

Its axial pump, which utilizes a 14.5 amp motor, may deliver a pressure of up to 2030 PSI (almost 34 times more than a standard garden hose) and a flow of up to 1.76 GPM. These values correspond to a cleaning power of 3572.8 Cleaning Units.

Since it is an electric pressure washer, the motor of the SPX4001 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

Thanks to its hand truck design and approximate dimensions of D21.2 x W19.3 x H36.6 in, the Sun Joe SPX4001 offers great mobility. The strong metal frame assures assembly longevity. The foam-padded fixed handle adds to the SPX4001 convenience of transport, while offering a comfortable grip.

Since the unit weighs only 32.4 lbs, it is very easily carried around. On top of its light weight, the transportability and easy of use of this model is further improved by the addition of two 8" wheels.

Main Features

The Sun Joe SPX4001 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 0.4 gal tank. The device has a dial which allows you to manually select the detergent dilution ratio. The detergent will be added automatically to the water when a soap nozzle is attached.
  • Pressure hose: The 20 ft ⌀1/4" high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a convenient hose reel, which also improves its lifespan.
  • Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
  • 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.
