Zoom on the Kärcher K2100PS

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

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

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

Its axial cam pump, which utilizes a 13 amp induction motor, may deliver a pressure of up to 2100 PSI (almost 35 times more than a standard garden hose) and a flow of up to 1.2 GPM. These values correspond to a cleaning power of 2520 Cleaning Units.

Kärcher allows you to easily start this electric pressure washer, utilizing the K2100PS's 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 allows the device to remain highly durable, 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. Its aluminum frame certainly plays a key role in this light weight. A set of two 10" never-flat wheels also improves the ease of transport of the device.

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: A safe detergent storage is facilitated by a removable 1 gal tank. The detergent will be added automatically to the water when a soap nozzle is attached.
  • Pressure hose: The 25 ft high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using 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 4 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
