Description
Zoom on the Sun Joe SPX3550
In a nutshell, the Sun Joe SPX3550 is a medium duty pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:
- spot cleaning of hard, unpainted surfaces and high-reach cleaning
- intense cleaning of tough, paintless surfaces
- cleaning of painted and frail surfaces
- use of detergent and cleaning solutions
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
With a 14.9 amp induction motor, its axial pump delivers a pressure of 2350 PSI (roughly 39 times more than a standard garden hose) and a flow of up to 1.8 GPM (values as per CSA testing standards). 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, resulting in the Sun Joe SPX3550's cleaning power of 2200 Cleaning Units.
Since it is an electric pressure washer, the motor of the SPX3550 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
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.
The unit can be very easily carried around, as it weighs just 24 lbs. 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
Along with the Sun Joe SPX3550 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 0.32 gal tank. The detergent dilution ratio is selected manually, via a dedicated dial. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
- Pressure hose: A neat storage for the included 20 ft high-pressure hose is facilitated by 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.
