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 values correspond to a cleaning power of 3700 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 is very mobile, due to its 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.

The unit can be very easily carried around, as it weighs just 45.9 lbs. 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.

Main Features

Along with the Sun Joe SPX4501 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.

  • Soap injection: Detergent is stored in a removable 1 gal tank. The washer has a dial that allows the user to manually select the detergent dilution ratio. The detergent is automatically added to the water when a soap nozzle is connected.
  • Pressure hose: The 20 ft 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: 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.
