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. Together, the values result in a cleaning power of 3572.8 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 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. As if this lightweight wasn't enough, the device also features two 8" wheels to further improve its ease of use and of transport.

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: 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. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
  • 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 table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.
