Power Comparison
- Fuel: Both units are electric pressure washers.
- Engine & Pump: The Sun Joe SPX3000 and the Sun Joe SPX3500 both use an axial-type pump to put water under pressure. Two main factors differentiate the motors used in these 2 units. To start with, the Sun Joe SPX3000's pump is powered by a 14.5-amp motor, while the Sun Joe SPX3500 uses a 13-amp one. But it should also be noted that, while the former is a standard, universal motor, the latter is an induction motor and thus, more energy-efficient, quiet and durable.
The following charts are provided to show you at a glance how the main specs of the Sun Joe SPX3000 compare to the Sun Joe SPX3500.
- Pressure: With a maximum reachable pressure of 2300 PSI, the Sun Joe SPX3500 provides a higher force to blast off dirt and grime than the 2030 PSI of the Sun Joe SPX3000.
- Water Flow: When operating at low pressure, the SPX3000 can generate a much higher maximum volume of water than the SPX3500. It can deliver up to 1.76 GPM (gallons per minute), whereas the SPX3500 offers a maximum water flow of 1.48 GPM. The former should thus allow you to rinse away dirt and debris with significantly better efficiency and speed.
- Cleaning Power: With its 3572.8 C.U. (Cleaning Units = PSI x GPM), the Sun Joe SPX3000 offers a somewhat higher overall cleaning efficiency than the SPX3500 and its 3404 C.U.
Design Comparison
- Design: With their compact design, both units are constructed with a strong focus on portability in mind.
- Weight: Weighing 23.4 lbs, the SPX3000 is far lighter than the 36.8 lbs of the SPX3500.
- Maneuverability: Both products benefit from a set of wheels, which greatly contributes to their maneuverability. Both offer a handle, which improves your grip when you wish to move them.
Feature Comparison
- Soap Addition: Both washers allow for the addition of chemical detergent solutions to the water. For that, the SPX3000 has an advantage over the SPX3500. The latter offers a single soap tank, whereas the former benefits from a dual soap tank system that lets you easily store and use 2 different cleaning solutions.
- Trigger Gun & Wand: Each of these 2 units comes with a fairly standard ergonomic trigger gun and a classic wand.
- Nozzles: Out of the box, the SPX3500 and the SPX3000 both come with a 5-nozzle package. The set of included nozzles is the same in either case: 0°, 15°, 25°, 40°, and a soap nozzle.
- Reach: Both products include a 20 ft high-pressure hose. Therefore, neither of them will, out of the box, allow for a higher freedom of movement around the unit. As both units feature a 35 ft power cord, their maximum allowable placement from an electrical outlet is the same.
- Storage: The SPX3000 and SPX3500 both offer onboard storage that allows you to neatly keep the accessories you need at hand. Both washers feature a set of hooks to help you neatly store their high pressure hoses when not in use.
