As the Sun Joe SPX3001 and the Kärcher K5 Premium have different manufacturers, their overall build and technology in use can vary.

Power Comparison

  • Fuel: Both units are electric pressure washers.
  • Engine & Pump: The Kärcher K5 Premium and the Sun Joe SPX3001 both use an axial-type pump to put water under pressure. The former's pump is manufactured by N-COR. Two main factors differentiate the motors used in these 2 units. To start with, the Kärcher K5 Premium's pump is powered by a 13-amp motor, while the Sun Joe SPX3001 uses a 14.5-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 Karcher K5 Premium compare to the Sun Joe SPX3001.

  • Pressure: With very similar maximum reachable pressures (2000 PSI for the Kärcher K5 Premium and 2030 PSI for the Sun Joe SPX3001), both devices should do an equally good job at lifting and blasting off dirt.
  • Water Flow: When operating at low pressure, the Sun Joe SPX3001 can generate a much higher maximum volume of water than the Kärcher K5 Premium. It can deliver up to 1.76 GPM (gallons per minute), whereas the Kärcher K5 Premium offers a maximum water flow of 1.4 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 SPX3001 offers a much higher overall cleaning efficiency than the Kärcher K5 Premium and its 2800 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 28.7 lbs, the K5 Premium is slightly less heavy than the SPX3001 (which weighs around 29.8 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. Whether you choose the Kärcher K5 Premium or the Sun Joe SPX3001, you'll be able to store your cleaning chemicals in the unit's onboard soap tank.
  • Trigger Gun & Wand: While each of these 2 units comes with a fairly standard ergonomic trigger gun, the Kärcher K5 Premium sports a VPS wand, while the Sun Joe SPX3001 has a classic one.
  • Nozzles: The Kärcher K5 Premium doesn't come with any nozzles (its aforementioned wand removes the need for any), but the Sun Joe SPX3001 is supplied with five (0°, 15°, 25°, 40°, and a soap nozzle).
  • Reach: With its included 25 ft high-pressure hose, the Kärcher K5 Premium will allow you, out of the box, to move farther away from the unit than the Sun Joe SPX3001 and its 20 ft high pressure hose. As both units feature a 35 ft power cord, their maximum allowable placement from an electrical outlet is the same.
  • Storage: In contrast to the SPX3001, which offers convenient onboard storage to keep your accessories at hand, the K5 Premium does not have such a feature. However, both feature a reel to allow you to conveniently and neatly store your pressure hose.
  • Accessories: In addition to the usual set of included accessories, the Kärcher K5 Premium also comes with dirt blaster and detergent tank.
