As the SPX3000-MAX and the SPX3500 are both Sun Joe pressure washers, they benefit from the same level of quality and attention to detail.

Power Comparison

  • Fuel: Both units are electric pressure washers.
  • Engine & Pump: The Sun Joe SPX3000-MAX and the Sun Joe SPX3500 both use an axial-type pump to put water under pressure. The Sun Joe SPX3000-MAX's pump is powered by a 14.5-amp motor, while the Sun Joe SPX3500 uses a 13-amp motor.

The following charts are provided to show you at a glance how the main specs of the Sun Joe SPX3000-MAX compare to the Sun Joe SPX3500.

  • Pressure: With a maximum reachable pressure of 2800 PSI, the Sun Joe SPX3000-MAX provides a much higher force to blast off dirt and grime than the 2300 PSI of the Sun Joe SPX3500.
  • Water Flow: When operating at low pressure, the SPX3500 can generate a noticeably higher maximum volume of water than the SPX3000-MAX. It can deliver up to 1.48 GPM (gallons per minute), whereas the SPX3000-MAX offers a maximum water flow of 1.3 GPM. The former should thus allow you to rinse away dirt and debris with quite better efficiency and speed.
  • Cleaning Power: With its 3640 C.U. (Cleaning Units = PSI x GPM), the Sun Joe SPX3000-MAX 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: With an approximate weight of 36.8 lbs, the SPX3500 is slightly less heavy than the SPX3000-MAX (which weighs around 37.5 lbs).
  • 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-MAX 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-MAX 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-MAX 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.
