Description
Zoom on the Kärcher K4 Power Control
The Kärcher K4 Power Control, a light to medium duty pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- precise spot cleaning of hard, unpainted surfaces, reaching elevated areas, and effectively removing stubborn stains
- mild cleaning for delicate surfaces, and low-pressure cleaning for broader areas
- applying detergent and cleaning solutions, and rinsing 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
Powered by a 13-amp induction motor, its axial cam pump can generate a forceful pressure of 1900 PSI (roughly 32 times that of a standard garden hose) and a flow rate 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. When these values are taken together, they yield a cleaning power of 1965 Cleaning Units.
With its electric design, the K4 Power Control starts up effortlessly with a quick press of an ON/OFF switch, ensuring ease of use. The unit is ready-to-use with peace of mind, thanks to the included GFCI cord.
Design & Handling
The Kärcher K4 Power Control's commitment to mobility is evident through its portable design and approximate dimensions of D15.8 x W12 x H23.1 in. The telescopic handle further eases storage and offers a convenient pulling height, allowing effortless transportation.
With its lightweight construction, tipping the scales at only 28.7 lbs, this unit is a portable powerhouse for all your cleaning needs. This owes partly to its plastic frame, contributing to its lightweight design. Complementing its lightweight frame, two 6.6" solid wheels are integrated, facilitating effortless transportation.
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 detergent dilution ratio can be manually selected, using the unit's adjustable detergent injection system. Detergent is automatically dispensed when the VPS wand is in "MIX" mode.
- Pressure hose: For easy organization, the included high-pressure hose can be stored on the unit using a set of convenient hooks when it's not in use, ensuring a clutter-free workspace.
- Spray gun and wand: Both the Power Control spray gun and its VPS wand may be conveniently 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
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".
