As the K1800PS and the K1700 are both Kärcher 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 Kärcher K1800PS and the Kärcher K1700 both use an axial-type pump to put water under pressure. The latter's pump is manufactured by N-COR. The Kärcher K1800PS's pump is powered by a 13-amp motor, while the Kärcher K1700 uses a 14-amp motor. Both motors are of the Universal type.

The following charts are provided to show you at a glance how the main specs of the Karcher K1800PS compare to the Karcher K1700.

  • Pressure: With a maximum reachable pressure of 1800 PSI, the Kärcher K1800PS provides a somewhat higher force to blast off dirt and grime than the 1700 PSI of the Kärcher K1700.
  • Water Flow: These 2 units offer the same maximum water flow. Each of them should be able to deliver a maximum of 1.2 GPM (gallons per minute) and to offer the same rinsing power.
  • Cleaning Power: With its 2160 C.U., the Kärcher K1800PS offers a somewhat higher overall cleaning efficiency than the K1700 and its 2040 C.U.

Design Comparison

  • Design: It is worth noting that the Kärcher K1700 has an aluminum frame, which means that it will not rust. With its compact, portable design, the Kärcher K1700 will be the better option if you consider portability, mobility, and ease of storage as important factors, as the Kärcher K1800PS can be considered less mobile, with a hand truck design. It is worth noting that the Kärcher K1700 has an aluminum frame, which means that it will not rust.

  • Weight: Considering that both devices weigh 20.7 lbs, neither of them will require more effort to be manually lifted and transported.
  • Maneuverability: Both products benefit from a set of wheels, which greatly contributes to their maneuverability. The K1800PS has the advantage of having a folding handle, which allows it to take up less space when not in use.

Feature Comparison

  • Soap Addition: Both washers allow for the addition of chemical detergent solutions to the water. Whether you choose the K1800PS or the K1700, you'll be able to store your cleaning chemicals in the unit's onboard soap tank. However, as the K1700 can hold 0.5 gal of cleaning solution, it benefits from a bigger detergent tank than the K1800PS and its 0.3 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 K1700 and the K1800PS both come with a 3-nozzle package. The set of included nozzles is the same in either case: 15°, soap, and a turbo 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 K1800PS and K1700 both offer onboard storage that allows you to neatly keep the accessories you need at hand. Both washers offer a way to store your high pressure hose. For the K1800PS, this is done via a dedicated slot on the top of the unit, while the K1700 allows it thanks to hooks.
  • Accessories: In addition to the usual set of included accessories, the Kärcher K1800PS also comes with a garden hose adapter.
