Description

Equipped with an eco-friendly, 14.9-amp motor, SPX3550 packs a super-powered punch, generating up to 2350 PSI (at initial discharge per CSA internal pressure testing) and 1.8 GPM (with nozzle open at minimum pressure) of pure cleaning power take on tough grease and oil stains, mildew, caked-on mud, and other stubborn gunk and grime.

Zoom on the Sun Joe SPX3550

In summary, the Sun Joe SPX3550 is a medium duty pressure washer, that offers an all-around versatile cleaning experience, and also:

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

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

Its axial pump, which utilizes a 14.9 amp induction motor, may deliver a pressure of up to 2350 PSI (almost 39 times more than a standard garden hose) and a flow of up to 1.8 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.

As it is an electric pressure washer, the motor of the SPX3550 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

With its portable design and approximate dimensions of D15 x W17 x H36 in, the Sun Joe SPX3550 makes mobility one of its core strengths. The handle adds to the SPX3550 convenience of transport.

With a weight of only 24 lbs, the unit is definitely easy to carry around. Its plastic frame certainly plays a key role in this light weight. To further improve its transportability and ease of use, the unit also features a set of two solid wheels.

Main Features

The Sun Joe SPX3550 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 0.32 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 20 ft high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
  • Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
  • Nozzles: The 5 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.
