As the SPX3001 and the SPX4001 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 SPX3001 and the Sun Joe SPX4001 both use an axial-type pump to put water under pressure. In either case, the pump is powered by a 14.5-amp motor.

The following charts are provided to show you at a glance how the main specs of the Sun Joe SPX3001 compare to the Sun Joe SPX4001.

  • Pressure: As the Sun Joe SPX3001 and the Sun Joe SPX4001 share the same maximum attainable pressure of 2030 PSI, they should both allow you to blast off dirt with the same force.
  • Water Flow: These 2 units offer the same maximum water flow. Each of them should be able to deliver a maximum of 1.76 GPM (gallons per minute) and to offer the same rinsing power.
  • Cleaning Power: Sharing an identical Cleaning Power of 3572.8 Cleaning Units (PSI x GPM), both devices offer the same overall cleaning efficiency.

Design Comparison

  • Design: With its compact, portable design, the Sun Joe SPX3001 will be the better option if you consider portability, mobility, and ease of storage as important factors, as the Sun Joe SPX4001 can be considered less mobile, with a hand truck design.
  • Weight: With an approximate weight of 29.8 lbs, the SPX3001 is slightly less heavy than the SPX4001 (which weighs around 32.4 lbs).
  • Maneuverability: Both products benefit from a set of wheels, which greatly contributes to their maneuverability. The SPX3001 has a standard handle and the SPX4001 a foam-padded handle, both of which aid in maneuvering.

Feature Comparison

  • Soap Addition: Both washers allow for the addition of chemical detergent solutions to the water. Whether you choose the SPX3001 or the SPX4001, you'll be able to store your cleaning chemicals in the unit's onboard soap tank. However, as the SPX4001 can hold 0.4 gal of cleaning solution, it benefits from a bigger detergent tank than the SPX3001 and its 0.32 gal tank.
  • 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 SPX4001 and the SPX3001 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 SPX3001 and SPX4001 both offer onboard storage that allows you to neatly keep the accessories you need at hand. Moreover, both feature a reel to allow you to conveniently and neatly store your pressure hose.
