Description
Zoom on the Kärcher K4 Power Control
The Kärcher K4 Power Control is a medium duty pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- pinpoint spot cleaning of hard, unpainted surfaces, accessing high areas, and successfully removing stubborn stains
- gentle cleaning for sensitive surfaces, and wide coverage cleaning with low pressure
- applying detergents and cleaning agents, and rinsing off 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
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). While these PSI and GPM values represent the maximum capabilities of the washer under specific conditions, it's important to note that under typical usage, the working pressure is 1500 PSI and the flow rate is 1.31 GPM, resulting in the Kärcher K4 Power Control's cleaning power of 1965 Cleaning Units.
The K4 Power Control is easily activated by an ON/OFF switch, offering convenient operation. The unit is ready-to-use with peace of mind, thanks to the included GFCI cord.
Design & Handling
Designed for on-the-go use, the Kärcher K4 Power Control offers a portable design and approximate dimensions of D15.8 x W12 x H23.1 in to facilitate easy movement. The telescopic handle further eases storage and offers a convenient pulling height, allowing effortless transportation.
Weighing in at a mere 28.7 lbs, this unit is designed for effortless portability and convenience. Its lightweight construction is partially attributed to its plastic frame. Adding to its lightweight construction, two 6.6" solid wheels are included, simplifying mobility and transport.
Main Features
The Kärcher K4 Power Control's package includes a spray gun, a wand, a pressure hose and a detergent injection feature, with a more detailed description below.
- Soap injection: Detergent supply is ensured by Karcher's Plug 'n' Clean system. The washer has an adjustable detergent injection system that allows the user to manually select the detergent dilution ratio. Detergent is automatically dispensed when the VPS wand is in "MIX" mode.
- Pressure hose: The included high-pressure hose can be neatly stored on the unit when not in use, utilizing a set of convenient hooks for convenient organization.
- 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".
