The Karcher K4 Full Control Pressure Washer is easy to put together and comes with multiple pressure options to suit a variety of cleaning tasks. Whether you're looking to clean delicate paintwork on your car, remove stubborn dirt from your bike frame or give your paving a new lease of life, the new Full Control system will help you select the best pressure for every surface.

The Karcher K4 comes with a Full Control trigger gun, a Vario Power lance and a Dirt Blaster spray lance, which deliver outstanding cleaning performance using concentrated rotating pressure. Simply choose the correct lance using the symbols on the accessories as a guide.

The Vario Power lance has four pressure settings and you can switch between them by simply twisting the nozzle. The LED display on the trigger gun allows you to check that the setting you’ve chosen is appropriate for the surface you’re cleaning, making it easy to find the perfect pressure. Meanwhile, the Dirt Blaster lance allows you to remove even the most stubborn of dirt from stone or brickwork.

The plug and clean function means that detergents can be applied quickly and easily when the pressure washer is in detergent mode. Karcher detergents increase efficiency while cleaning, help prevent dirt from returning and help to protect and care for your surfaces.

The Karcher K4 includes a telescopic handle and wheels so it’s easy to move. The upright design saves valuable space, while the front-facing on-board storage ensures that the trigger gun and lances are easily accessible. The plastic casing is impact-resistant and durable, with all components and fixings designed to the highest Karcher quality standards.

Q&A

Q: How do I use the Karcher K4?
A: Check out Karcher’s guide to assembling and using the Karcher K4 pressure washer.

Q: How do I remove the hose from a Karcher K4?
A: If you have the premium model, unwind your high-pressure hose from the hose reel. If you have the non-premium model, simply take your high-pressure hose off the hook at the back of the pressure washer.

There is a sliver clip where your high-pressure hose connects to your pressure washer. Pull the clip away from the machine and then pull the hose out of the fitting. You will need to keep your clip safe, as this will be needed to reattach your hose.

Q: What PSI is a Karcher K4?
A: The Karcher K4 uses bar pressure to measure HPW pressure. To convert bar pressure to PSI, multiply the bar pressure by 14.75. The maximum bar pressure for the Karcher K4 is 130, so the PSI is 1,917.5.
