Description
Zoom on the Kärcher K4 Power Control
In summary, the Kärcher K4 Power Control is a light to medium duty pressure washer, that offers an all-around versatile cleaning experience, and also:
- spot cleaning of hard, paintless surfaces and reaching far-away areas
- cleaning of painted and frail surfaces
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
With a 13 amp induction motor, its axial cam pump delivers a pressure of 1900 PSI (roughly 32 times more than a standard garden hose) and a flow of up to 1.5 GPM (values claimed by the manufacturer). These are the maximum values that the washer can reach only under specific conditions. Under typical load, working pressure is 1500 PSI and rated flow is 1.31 GPM, resulting in the Kärcher K4 Power Control's cleaning power of 1965 Cleaning Units.
The K4 Power Control is an electric pressure washer and thus, can be easily started by an ON/OFF switch. The unit is ready-to-use with peace of mind, thanks to the included GFCI cord.
Design & Handling
With its portable design and approximate dimensions of D15.8 x W12 x H23.1 in, the Kärcher K4 Power Control makes mobility one of its core strengths. The telescopic handle further eases storage and offers a convenient pulling height, allowing effortless transportation.
With a weight of only 28.7 lbs, the unit is definitely easy to carry around. Among other factors, the plastic frame plays a 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 6.6" solid wheels.
Main Features
The Kärcher K4 Power Control comes with a spray gun, a wand and a pressure hose, which are detailed below.
- Pressure hose: This washer comes with an easy-to-connect high-pressure hose. However, it doesn't feature any proper storage solution for it (no reel, strap or hook).
- Spray gun and wand: The included Power Control spray gun and its VPS wand can be easily stored in a side hook. The Vario Power Spray (VPS) wand allows you to conveniently switch from low to high pressure, and everything between, while you clean. Simply twist the end for infinitely variable pressure adjustment.
Plug 'n' Clean System
The practical Plug 'n' Clean system allows you to change the detergent in one quick and easy step, and to always see the filling level at a glance.
It removes the need for a proper soap tank, as you just have to plug your chosen Karcher detergent upside down in the unit's dedicated chamber.
6 Plug 'n' Clean detergents are available: Ultra Foam Cleaner, Plastic Cleaner, Wood Cleaner, Stone & Facade Cleaner, Car Shampoo, and Universal Cleaner.
Power Control Gun
The Power Control trigger gun and its pressure display
Karcher's Power Control trigger gun gives you an instant reading on your current pressure setting.
It features indicators that illuminate to show you which of the 4 settings the Vario Power Spray wand is currently set.
The four settings are "MIX", "SOFT", "MEDIUM", and "HARD".

- The Karcher K4 Power Control, 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 $300-400 price range.

- As this washer can produce a flow of water of 1.5 GPM (gallons per minute), it is average in terms of water volume for the above-mentioned price range.
