With the K 5 Premium Full Control Plus you can effortlessly find the right pressure for every cleaning job. The pressure level is indicated on a LCD display on the spray gun and can be adjusted using the +/– buttons. The spray gun communicates via radio frequency with the motor to adjust the pressure. Select the spray pattern by simply twisting the included 3-in-1 Multi Jet spray lance. No longer worry about switching spray wands – even when going from high-pressure mode to detergent mode. In the event of short breaks, you can also easily stow the spray gun and lance onboard. An extendible telescopic handle enables the pressure washer to be pulled along conveniently and stored so that it takes up less space. And the practical Plug 'n' Clean system means you can change the detergent in one quick and easy step, as well as see the detergent level at a glance. With a lower center of gravity, useful hose guide and stand that lends even greater stability, the K 5 Premium Full Control Plus offers unrivaled ease of use. (source: Kärcher (opens in a new tab))

The Kärcher K5 Premium Full Control Plus

Using a 12.4 amp induction motor, its axial pump delivers a pressure of up to 2000 PSI (roughly 33 times more than a standard garden hose) and a flow of up to 1.4 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 2800 Cleaning Units.

As it is an electric pressure washer, the motor of the K5 Premium Full Control Plus gets easily started by a simple ON/OFF switch. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.

Design & Handling

With its portable design and approximate dimensions of D16.18 x W12 x H23 in, the Kärcher K5 Premium Full Control Plus makes mobility one of its core strengths. The telescopic handle further eases storage and offers a convenient pulling height, allowing effortless transportation.

The unit can be very easily carried around, as it weighs just 32.19 lbs. Its plastic frame certainly plays a key role in this light weight. A set of two 6.6" wheels also improves the ease of transport of the device.

The Kärcher K5 Premium Full Control Plus

The Kärcher K5 Premium Full Control Plus'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 Kärcher K5 Premium Full Control Plus benefits from an adjustable soap dilution ratio, provided by its Full Control Plus trigger gun. Detergent will be added automatically to the water whenever the 3-in-1 Multi-jet lance is set to the "soap" position.
  • Pressure hose: Using a convenient hose reel, which also improves its lifespan, the included 25 ft ⌀3/8" high-pressure hose can be easily stored on the unit when it is not running.
  • Spray gun and wand: The included Full Control Plus spray gun and its 3-in-1 Multi-jet wand can be easily stored in a front sheath. The 3-in-1 lance allows incredibly flexible working conditions. It replaces the need for nozzle swaps and offers an infinitely adjustable high-pressure flat stream, a rotary nozzle and a cleaning agent jet. The appropriate jet is selected simply by turning the spray lance.

Plug 'n' Clean System

Karcher 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.

Combined with the 3-in-1 Multi-jet wand, it offers excellent control, convenience, versatility and flexibility.

Other Features
