Power

The Sun Joe SPX3500 in use

The Sun Joe SPX3500

With a 13 amp motor, its axial pump delivers a pressure of 2000 PSI (roughly 33 times more than a standard garden hose) and a flow of up to 1.09 GPM, resulting in the Sun Joe SPX3500's cleaning power of 2180 Cleaning Units.

The SPX3500 is an electric pressure washer and thus, can be easily started 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 SPX3500 makes mobility one of its core strengths. The handle adds to the SPX3500 convenience of transport.

With a weight of only 36.8 lbs, the unit is definitely easy to carry around. Its plastic frame certainly plays a key role in this light weight. A set of two solid wheels also improves the ease of transport of the device.

Main Features

Along with the Sun Joe SPX3500 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 washer has a dial that allows the user to manually select the detergent dilution ratio. The detergent will be added automatically to the water when a soap nozzle is attached.
  • Pressure hose: Using a set of convenient hooks, the included 20 ft high-pressure hose can be easily stored on the unit when it is not running.
  • Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
  • Nozzles: The 5 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

  • Reaching a 2000 PSI max pressure output, the Sun Joe SPX3500 has an expected pressure value, compared to the other electric units in the $150 to $200 price range.

  • In comparison to other devices in the above-mentioned price range, this washer and its 1.09 GPM (gallons per minute), has one of the lower GPM values. If rinsing away debris most efficiently is your priority, one of the devices with the highest GPM in this price range is the WEN PW21, which can reach up to 1.76 GPM.
  • The SPX3500's Cleaning Units, 2180 CU (PSI x GPM), fall into the lower end when compared to electric devices of similar price. If you consider the highest overall cleaning power as a really important factor, the Realm BY02-BIMK and its 4550 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.
