Description

The K1900PS electric pressure washer is perfect for tackling typical home cleaning tasks. Karcher electric models offer solid cleaning ability that is high on value and big on performance. (source: Kärcher (opens in a new tab))

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

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

Power

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.

Main Features

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.
  • Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a front sheath.
  • Nozzles: The 3 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

The Kärcher K1900PS's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Kärcher K1900PS compare to similarly priced pressure washers.

  • With a maximum pressure output of 1900 PSI, the Kärcher K1900PS finds itself in the expected pressure range among electric units that cost between $150 and $180. If your priority is the highest possible power of the water stream, in this price range, we suggest checking out the Westinghouse WPX2300e, which reaches up to 2300 PSI.
  • In the aforementioned price range, this washer, with 1.2 GPM (gallons per minute), is placed on the lower end of the GPM scale. If rinsing away debris most efficiently is your priority, one of the devices with the highest GPM in this price range is the Westinghouse WPX2300e, which can reach up to 1.76 GPM.
  • Reaching up to 2280 Cleaning Units (PSI X GPM), the K1900PS is one of the more efficient amongst its similarly priced peers. When it comes to the highest overall cleaning power in the current price range, one of the products at the very top currently is the DeWalt DWPW2100 and its 2520 Cleaning Units.

Price comparison

As you can see from these interactive charts, when compared to other electric washers between 2000 and 2500 Cleaning Units, the Karcher K1900PS is on the average side of the price range.

Therefore, this pressure washer nicely fits in the expected budget for this kind of cleaning power.

    Very disappointed by this great Karcher brand, hose too rigid not in rubber and now does not want to start, same quality as less known brands for a higher price.

    + PROS: Brand name
    - CONS: Plastic hose, poor quality, hose in the bottom of the soap tank fell out on the first day.
