Power

The Sun Joe SPX4001 in use

The Sun Joe SPX4001

Using a 14.5 amp universal motor, its axial pump delivers a pressure of up to 2030 PSI (roughly 34 times more than a standard garden hose) and a flow of up to 1.76 GPM. These are the maximum values that the washer can reach only under specific conditions. Under typical load, working pressure is 1450 PSI and rated flow is 1.24 GPM. Together, the values result in a cleaning power of 1798 Cleaning Units.

As it is an electric pressure washer, the motor of the SPX4001 gets easily started by a simple 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 SPX4001 offers superb mobility, with a hand truck design and approximate dimensions of D21.2 x W19.3 x H36.6 in. The robust metal frame guarantees longevity of the assembly. The foam-padded fixed handle adds to the SPX4001 convenience of transport, while offering a comfortable grip.

With a weight of only 32.4 lbs, the unit is definitely easy to carry around. To further improve its transportability and ease of use, the unit also features a set of two 8" wheels.

Main Features

The Sun Joe SPX4001'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: A safe detergent storage is facilitated by a removable 0.4 gal tank. The detergent dilution ratio can be manually selected, using a dial. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • Pressure hose: The included 20 ft ⌀1/4" high-pressure hose can be neatly stored on the unit when idle thanks to 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 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
