Further down the page, you'll find some explanations regarding the key similarities and differences between the Kärcher K2000 and the Kärcher K1800.
But before checking out explanations regarding their power, design, and features here's a table that summarizes the main pros of each of these 2 pressure washers:

Power Comparison
- Fuel: Both units are electric pressure washers.
- Engine & Pump: The Kärcher K2000 and the Kärcher K1800 both use an axial-type pump to put water under pressure. Two main factors differentiate the motors used in these 2 units. To start with, the Kärcher K2000's pump is powered by a 13-amp motor, while the Kärcher K1800 uses a 14-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 K2000 compare to the Karcher K1800.
- Pressure: With a maximum reachable pressure of 2000 PSI, the Kärcher K2000 provides a higher force to blast off dirt and grime than the 1800 PSI of the Kärcher K1800.
- Water Flow: When operating at low pressure, the K2000 can generate a higher maximum volume of water than the K1800. It can deliver up to 1.3 GPM (gallons per minute), whereas the K1800 offers a maximum water flow of 1.2 GPM. The former should thus allow you to rinse away dirt and debris with better efficiency and speed.
- Cleaning Power: With its 2600 C.U. (Cleaning Units = PSI x GPM), the Kärcher K2000 offers a much higher overall cleaning efficiency than the K1800 and its 2160 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: Weighing 21.4 lbs, the K1800 is far lighter than the 44.5 lbs of the K2000.
- Maneuverability: Both products benefit from a set of wheels, which greatly contributes to their maneuverability. Both offer a folding 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 K2000 has an advantage over the K1800. 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: Both pressure washers come with 15°, soap, and turbo nozzles, but the nozzle similarities stop here. The K2000 also has a 40° nozzle.
- Reach: Both products include a 25 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 K2000 and K1800 both offer onboard storage that allows you to neatly keep the accessories you need at hand. The K1800 features a set of hooks to neatly store its pressure hose. However, the K2000 pushes the convenience further by offering a hose reel.
