Pressure Washer Karcher K 5 Premium Smart Control Flex — electric upright, 145 bar, up to 500 l/h, 2100 W, 10 m hose
The Kärcher K 5 Premium Smart Control Flex is an electric upright pressure washer with a maximum flow rate of 500 l/h and a power consumption of 2100 W. With Bluetooth connectivity to the Kärcher Home & Garden app, the device transfers recommended pressure settings to the Smart Control trigger gun and offers on‑screen guidance for many cleaning tasks. Built features include a G 180 Q Smart Control trigger gun with LCD display, a 3‑in‑1 Multi Jet spray lance, Plug 'n' Clean detergent system, a 10 m PremiumFlex high‑pressure hose, aluminium telescopic handle, Quick Connect coupling and a parking position for accessories.
The integrated Bluetooth connection and app support enable guided setup, optimal pressure settings and access to maintenance and service information directly from a smartphone. The Smart Control trigger gun has an LCD display for pressure readout and buttons to adjust pressure or detergent dosing; a boost mode provides extra power for stubborn dirt. The PremiumFlex hose and Quick Connect system increase mobility and ease of handling, while the water‑cooled motor and upright design contribute to stable operation and long service life.
Connect the pressure washer to a suitable power supply and water source, attach the PremiumFlex high‑pressure hose using Quick Connect and fit the G 180 Q Smart Control trigger gun and chosen nozzle on the 3‑in‑1 Multi Jet lance. Pair the device with the Kärcher Home & Garden app via Bluetooth to receive application recommendations and transfer the optimal pressure to the trigger gun, or set pressure directly on the gun using the LCD and control buttons. Use Plug 'n' Clean cartridges to load detergent if required. Engage boost mode when extra cleaning power is needed and always follow safety instructions in the user manual.
For best results, start with a lower pressure and the app’s application consultant to select the appropriate pressure and nozzle for the surface. Rinse surfaces after detergent application and store the hose neatly on the reel in the parking position to prolong hose life.
