Yes, a device can be registered several times so it is available to different users.
The high-pressure cleaner can store a maximum of 5 different Bluetooth devices and automatically reconnect to them.
The connection between the app and the device is made via Bluetooth. The connection between the gun and the device is made via a standard 868 MHz radio band.
The radio and Bluetooth symbols on the gun display are shown continuously and do not flash.
You can find the operating instructions enclosed in your device shipping box or online at kaercher.com.
K 4, K 5 and K 7 models have an integrated suction mechanism and can therefore draw in water from alternative water sources. For this purpose, you also need the suction hose with filter (order no.: 2.643-100.0).
Attach the suction hose to the device at the water supply. Put the other end in the water butt. Connect the high-pressure hose to the device. Before you switch on the device, remove the spray lance from the gun. Press the lever on the gun so that it is open and now switch on your device. In this way, the air in the device can easily escape and the high-pressure cleaner starts to draw in the water. The device should not be positioned more than 0.5 m above the tapping point.
No. This function is offered by the devices of the Compact series.
Yes, this is possible. It is advisable to put a waterproof film under the device before transporting.
Kärcher high-pressure cleaners can operate at an input temperature of up to 40 °C.
The device needs a “warm-up phase” for 30 seconds until boost mode is available. Alternatively: Please check the temperature of the water; boost can only be triggered when the motor temperature is low.
An electrically operated pump works in a high-pressure cleaner, which increases the water pressure many times over ─ up to 195 bar. With this pressure, water is transported through the high-pressure hose to a lance, where it emerges as a sharp, focused jet from a nozzle and, thus, develops substantial cleaning power. If the hand trigger gun is not operated, the pump switches off automatically. This means you can do your cleaning work faster than with conventional methods and you also have low water consumption.
Depending on the model, Kärcher high-pressure cleaners for private use have a flow rate of between 230 and 600 l/h (for comparison: Around 3,500 litres of water flow through a garden hose every hour.). The high-pressure cleaner is easy on the wallet and the environment.
Kärcher recommends a distance to the object to be cleaned of between 12 and 40 cm.
Check the wireless and Bluetooth connection on the gun display. Re-pair the gun if either or both of the icons are flashing or are not displayed.
No. The detergent has a boiling point that is well above the temperature to which the detergent is exposed when used and stored as intended.
You can find suitable accessories for your device in our Kärcher accessories finder at kaercher.com, in our online shop or in specialist shops.

Disconnect the device from the water supply. Turn on the device and press the gun lever until no more water comes out of the device. Switch off the device and stow the accessories, high-pressure hose and cables on the device. The device should be stored in a temperature-protected place during the winter.
The high-pressure cleaner should be stowed in a dry place protected from the cold, e.g. in a garage. After cleaning, the device should be switched off and the water pressure bled by removing the high-pressure gun from the device. The spray lances, high-pressure hose and cable should be stowed on the device.
Unscrew the water connection from the device by hand, pull out the sieve with flat-nose pliers and clean under running water. Then insert the sieve again and screw on the water connection.
