The K 4 Power Control pressure washer makes it unbelievably easy to clean every surface at the right pressure. And thanks to the Kärcher Home & Garden app it is also very easy to find the right pressure. The application consultant integrated in the app supports the user with practical tips on every cleaning situation and cleaning object – for perfect cleaning results. Apart from the application consultant, the app offers other helpful functions such as assembly instructions, as well as maintenance and care instructions. When the right pressure level has been found, it can be easily set by turning the spray lance and checked on the G 160 Q Power Control spray gun. The K 4 Power Control also impresses with the Kärcher Plug 'n' Clean detergent system for effortless changeover of the detergent, a telescopic handle for comfortable transportation, as well as onboard storage for readily accessible accessories.
