Description
Zoom on the Kärcher K1900
In summary, the Kärcher K1900 is a light to medium duty pressure washer, which provides:
- thorough cleaning of hard, paint-free surfaces
- cleaning of painted or delicate surfaces
- applying detergent and cleaning solutions
- intense cleaning of hard surfaces
The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.
Power
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 made starting the motor of this electric pressure washer as easy as possible, since the K1900 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 D18.3 x W19 x H35.5 in, the Kärcher K1900 provides great mobility. The aluminum frame grants the device a good durability, as it will not rust. The folding handle enhances its mobility, while allowing for a convenient storage.
Since the unit weighs only 39.3 lbs, it is very easily carried around. This is, in part, thanks to its aluminum frame, which allows it to remain as lightweight as possible. On top of its light weight, the transportability and ease of use of this model is further improved by the addition of two 10" wheels.
Main Features
The Kärcher K1900's package includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: A safe detergent storage is facilitated by a removable 1 gal tank. However, since the Kärcher K1900 does not feature a soap dilution mechanism, you'll have to make sure your detergent is correctly diluted before use. The detergent is automatically added to the water when a soap nozzle is connected.
- Pressure hose: A neat storage for the included 25 ft high-pressure hose is facilitated by a set of convenient hooks.
- Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a front sheath.
- Nozzles: The 4 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.
15° | 40° | Soap | Turbo | |
|---|---|---|---|---|
| Concrete, brick, masonry | Suitable | Suitable | Suitable | Use with caution |
| Siding, gutters, house | Use with caution | Suitable | Suitable | Not recommended |
| Fencing, deck, patio | Use with caution | Suitable | Suitable | Not recommended |

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, a device which can produce up to 1900 PSI, is on the lower end of the pressure spectrum, among the electric pressure washers in the $195-255 price range. If the highest possible power of the water stream is your priority, one of the champions in this price range is the Sun Joe SPX4600 with 3000 PSI.
- As this washer can produce a flow of water of 1.3 GPM (gallons per minute), it is average in terms of water volume for the above-mentioned price range. If being able to rinse away debris as efficiently as possible is your priority, one of the products with the highest GPM in this price range is the Sun Joe SPX3550, with 1.8 GPM.
- As the K1900 has a total of 2470 Cleaning Units (PSI X GPM), it finds itself in the average cleaning efficiency range for similarly priced electric units. If you consider the highest overall cleaning power as a really important factor, the Pulsar PWE2019 and its 3200 Cleaning Units has one of the highest cleaning efficiency of all the similarly priced units.
Here's a list of the most popular specific comparisons:

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.
