As the SPX4600 and the SPX4500 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 SPX4600 and the Sun Joe SPX4500 both use an axial-type pump to put water under pressure. The Sun Joe SPX4600's pump is powered by a 14.5-amp motor, while the Sun Joe SPX4500 uses a 13-amp motor.

The following charts are provided to show you at a glance how the main specs of the Sun Joe SPX4600 compare to the Sun Joe SPX4500.

  • Pressure: With a maximum reachable pressure of 2300 PSI, the Sun Joe SPX4600 provides a higher force to blast off dirt and grime than the 2000 PSI of the Sun Joe SPX4500.
  • Water Flow: These 2 units offer the same maximum water flow. Each of them should be able to deliver a maximum of 1.1 GPM (gallons per minute) and to offer the same rinsing power.
  • Cleaning Power: With its 2530 C.U. (Cleaning Units = PSI x GPM), the Sun Joe SPX4600 offers a higher overall cleaning efficiency than the SPX4500 and its 2200 C.U.

Design Comparison

  • Design: Both units are constructed with a hand truck design. Therefore, if either of these 2 devices should provide better mobility, it would be due to its wheels and weight (which we detail just below).
  • Weight: With an approximate weight of 36.6 lbs, the SPX4600 is slightly less heavy than the SPX4500 (which weighs around 37 lbs).
  • Maneuverability: Both products benefit from a set of wheels, which greatly contributes to their maneuverability. Both offer a foam-padded 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. Whether you choose the SPX4600 or the SPX4500, you'll be able to store your cleaning chemicals in the unit's onboard soap tank. Their soap capacity is equal, as the tanks of both units can hold 1 gal of detergent.
  • 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 SPX4500 and the SPX4600 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 SPX4600 and SPX4500 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.
