Zoom on the Kärcher K1900PS
The Kärcher K1900PS is a light to medium duty pressure washer, and enables:
- intense cleaning of hard, unpainted surfaces
- use of detergent and cleaning solutions
- intense cleaning of hard surfaces
Using a 13 amp universal motor, its axial pump delivers a pressure of up to 1900 PSI (roughly 32 times more than a standard garden hose) and a flow of up to 1.2 GPM (CETA-certified values). Together, the values result in a cleaning power of 2280 Cleaning Units.
Kärcher made starting the motor of this electric pressure washer as easy as possible, since the K1900PS 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 hand truck design and approximate dimensions of D17.5 x W17.7 x H33.1 in, the Kärcher K1900PS provides great mobility. 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.
Because the device weighs just 20.9 lbs, carrying it around is very easy. Its aluminum frame certainly plays a key role in this light weight. On top of its light weight, the transportability and ease of use of this model is further improved by the addition of two 8" never-flat wheels.
Along with the Kärcher K1900PS itself, the package also includes a spray gun, a wand, a pressure hose, 3 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: Detergent storage is ensured by a removable 0.3 gal tank. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
- Pressure hose: A neat storage for the included 20 ft high-pressure hose is facilitated by a dedicated slot.
