Thanks to integrated Bluetooth, the K 5 Premium Smart Control Flex pressure washer can be connected to the Kärcher Home & Garden app. This means the user is optimally supported via smartphone in many cleaning situations and many cleaning tasks - and can achieve even more efficient cleaning results. The app offers many useful functions, such as the application advisor with useful tips and tricks, installation instructions, maintenance and care instructions and the Kärcher Service Portal. It also features a boost mode for extra power, a G 180 Q Smart Control spray gun with LCD display and the 3-in-1 Multi Jet spray lance. Pressure is set either on the spray gun itself or transferred to the spray gun using the app's application advisor. The LCD display can be used to check which pressure level is set. Other features of the kit include the Plug 'n' Clean detergent system, the PremiumFlex high-pressure hose, the telescopic aluminium handle, the Quick Connect system that allows you to click the high-pressure hose in and out of the unit and spray gun, and the parking position so you can always access accessories.
