Its power characteristics and design, its main features and all its additional features are presented ahead.


The Kärcher K5 Premium Smart Control in use

The Kärcher K5 Premium Smart Control

Powered by a 13 amp induction motor, its axial pump can deliver a pressure of 2000 PSI (around 33 times more than a standard garden hose) and a flow of up to 1.55 GPM (values claimed by the manufacturer). These are maximum values that can only be reached in specific conditions. Under typical load, working pressure is 1700 PSI and rated flow is 1.32 GPM. Combined, these values mean that the Kärcher K5 Premium Smart Control has a cleaning power of 2244 Cleaning Units.

Being an electric pressure washer, the Kärcher K5 Premium Smart Control's motor can be easily started by a convenient 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 D16.3 x W12 x H23.1 in, the Kärcher K5 Premium Smart Control makes mobility one of its core strengths. The telescopic handle further eases storage and offers a convenient pulling height, allowing effortless transportation.

Standing at only 31.7 lbs, this model can be carried around very easily. This is, in part, thanks to its plastic frame, which allows it to remain as lightweight as possible. To further improve its transportability and ease of use, the unit also features a set of two 6.6" solid wheels.

Main Features

The Kärcher K5 Premium Smart Control comes with a spray gun, a wand, a pressure hose and a detergent injection feature, which are detailed below.

  • Soap injection: Detergent supply is ensured by Karcher's Plug 'n' Clean system. The Kärcher K5 Premium Smart Control benefits from an adjustable soap dilution ratio, provided by its Smart Control trigger gun. Under the "soap" position of the 3-in-1 Multi-jet lance, the unit will proceed to add the detergent to the water.
  • Pressure hose: Using a convenient hose reel, which also improves its lifespan, the included high-pressure hose can be easily stored on the unit when it is not running.
  • Spray gun and wand: The included Smart Control spray gun and its 3-in-1 Multi-jet wand can be easily stored in a dedicated slot. 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.

The unit also features Bluetooth connectivity, which allows it to communicate with the Home & Garden Mobile App.

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.
