Zoom on the Kärcher K2100PS

In summary, the Kärcher K2100PS is a medium duty pressure washer, which provides:

  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted or delicate surfaces
  • application of detergent and cleaning solutions
  • intense cleaning of hard surfaces

Ahead are presented its power characteristics and design, its main features and any other additional features.

Power

The Kärcher K2100PS's axial cam pump, powered by a 13 amp induction motor, can provide a pressure of up to 2100 PSI (approximately 35 times more than a standard garden hose) and a flow of up to 1.2 GPM (CETA-certified values). The Kärcher K2100PS thus has a cleaning power of 2520 Cleaning Units.

Kärcher made starting the motor of this electric pressure washer as easy as possible, since the K2100PS gets easily started by stepping on an ON/OFF pedal. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.

Design & Handling

With its portable design and approximate dimensions of D18.9 x W18.5 x H35.4 in, the Kärcher K2100PS makes mobility one of its core strengths. The aluminum frame ensures the device's durability, as it will not rust. The folding handle enhances its mobility, while allowing for a convenient storage.

Standing at only 39.7 lbs, this model can be carried around very easily. It is lightweight, partly thanks to its aluminum frame. As if this lightweight wasn't enough, the device also features two never-flat wheels to further improve its ease of use and of transport.

Main Features

Along with the Kärcher K2100PS itself, the package also includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: Detergent storage is ensured by a removable 1 gal tank. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
  • Pressure hose: A neat storage for the included 25 ft high-pressure hose is facilitated by a dedicated slot.
  • Spray gun and wand: A dedicated slot allows for an easy storage of the included classic ergonomic spray gun and its wand.
  • Nozzles: The table below shows you the 4 included nozzles, as well as the surfaces they're the most appropriate for.
