Zoom on the Kärcher K1900

The Kärcher K1900 is a light to medium duty pressure washer, and enables:

  • intense cleaning of tough, paintless surfaces
  • cleaning of painted and frail surfaces
  • applying 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 K1900 in use

The Kärcher K1900

The Kärcher K1900's axial pump, powered by a 13 amp induction motor, can provide a pressure of up to 1900 PSI (approximately 32 times more than a standard garden hose) and a flow of up to 1.3 GPM (CETA-certified values). The Kärcher K1900 thus has a cleaning power of 2470 Cleaning Units.

Kärcher allows you to easily start this electric pressure washer, utilizing the K1900's ON/OFF pedal. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.

Design & Handling

The Kärcher K1900 is very mobile, due to its hand truck design and approximate dimensions of D18.3 x W19 x H35.5 in. 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.

With a weight of only 39.3 lbs, the unit is definitely easy to carry around. Among other factors, the aluminum frame plays a role in this light weight. To further improve its transportability and ease of use, the unit also features a set of two 10" wheels.

Main Features

Along with the Kärcher K1900 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. It must be noted that the Kärcher K1900 doesn’t come with a soap dilution mechanism. Therefore, you must always make sure that your detergent is correctly diluted. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • Pressure hose: Using a set of convenient hooks, the included 25 ft high-pressure hose can be easily stored on the unit when it is not running.
  • Spray gun and wand: A front sheath enables you to easily store the included classic ergonomic spray gun and its wand.
  • Nozzles: The following table illustrates the 4 included nozzles, along with the surfaces which they are the most suitable for.

The Kärcher K1900's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Kärcher K1900 compare to similarly priced pressure washers.

  • The Karcher K1900 with its 1900 PSI achieves a lower pressure value, compared to other electric pressure washers in the $255-300 price range. If you're going after the highest possible power of the water stream, one of the best in this price range is the Realm BY02-BIMH-3000 that can reach up to 3000 PSI.
  • In comparison to other devices in the above-mentioned price range, this washer and its 1.3 GPM (gallons per minute), has one of the lower GPM values. If rinsing away debris most efficiently is your priority, one of the devices with the highest GPM in this price range is the Greenworks GPW2700, which can reach up to 2.3 GPM.
  • Amongst similarly priced electric devices, the 2470 Cleaning Units (PSI x GPM) of the K1900 rank as low. If you consider the highest overall cleaning power as a really important factor, the Greenworks GPW2700 and its 6210 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.

Price comparison

As you can see from this interactive chart, when compared to other electric washers between 2000 and 2500 Cleaning Units, the Karcher K1900 is on the expensive side of the price range.

While certainly not the cheapest of its cleaning power range, purchasing it could most likely also mean enjoying the reliability of a high-end product.

    Works very well when it works. I bought 2 , one for the house and one for the cottage. It worked for about 3 or 4 times . Than the gun start leaking and not able to build pressure. I opened the gun and the valve is too weaks to handled the pressure and cracked . They both have exactly the same problem. I’m waiting to receive a new gun under warranty but unless they upgraded the valve the situation will be the same.

    + PROS: Good performance
    - CONS: Broke very quickly.
