Power Comparison
- Fuel: Both units are electric pressure washers.
- Engine & Pump: The Kärcher K1900 and the Kärcher K1800PS both use an axial-type pump to put water under pressure. In either case, the pump is powered by a 13-amp motor. However, the Kärcher K1900 has the advantage of featuring an induction motor which is more energy-efficient, quiet and durable than the universal motor of the Kärcher K1800PS.
The following charts are provided to show you at a glance how the main specs of the Karcher K1900 compare to the Karcher K1800PS.
- Pressure: With a maximum reachable pressure of 1900 PSI, the Kärcher K1900 provides a somewhat higher force to blast off dirt and grime than the 1800 PSI of the Kärcher K1800PS.
- Water Flow: When operating at low pressure, the K1900 can generate a higher maximum volume of water than the K1800PS. It can deliver up to 1.3 GPM (gallons per minute), whereas the K1800PS 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 2470 C.U., the Kärcher K1900 offers a higher overall cleaning efficiency than the K1800PS 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). It is worth noting that the Kärcher K1900 has an aluminum frame, which means that it will not rust.
- Weight: Weighing 20.7 lbs, the K1800PS is far lighter than the 39.3 lbs of the K1900.
- 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. Whether you choose the K1900 or the K1800PS, you'll be able to store your cleaning chemicals in the unit's onboard soap tank. However, as the K1900 can hold 1 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: Both pressure washers come with 15°, soap, and turbo nozzles, but the nozzle similarities stop here. The K1900 also has a 40° nozzle.
- Reach: With its included 25 ft high-pressure hose, the Kärcher K1900 will allow you, out of the box, to move farther away from the unit than the Kärcher K1800PS 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: The K1900 and K1800PS 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 K1900, this is done via a set of hooks, while the K1800PS allows it thanks to a dedicated slot on the top of the unit.
- Accessories: In addition to the usual set of included accessories, the Kärcher K1800PS also comes with a garden hose adapter.
