Zoom on the Sun Joe SPX3501
In a nutshell, the Sun Joe SPX3501 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
The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.
Using a 13 amp induction motor, its axial pump delivers a pressure of up to 2300 PSI (roughly 38 times more than a standard garden hose) and a flow of up to 1.48 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 1.09 GPM. Together, the values result in a cleaning power of 2180 Cleaning Units.
Since it is an electric pressure washer, the motor of the SPX3501 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 D16.7 x W14.5 x H36 in, the Sun Joe SPX3501 makes mobility one of its core strengths. The handle adds to the SPX3501 convenience of transport.
With a weight of only 41 lbs, the unit is definitely easy to carry around. Among other factors, the plastic frame plays a role in this light weight. As if this lightweight wasn't enough, the device also features two solid wheels to further improve its ease of use and of transport.
Along with the Sun Joe SPX3501 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: A safe detergent storage is facilitated by a removable 0.32 gal tank. The detergent dilution ratio can be manually selected, using a dial. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
- Pressure hose: The included 20 ft 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: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
- Nozzles: The following table illustrates the 5 included nozzles, along with the surfaces which they are the most suitable for.
