With its water-cooled motor, it cleans up to 60 m²/h. It is equipped with a 10 m long Premium Flex hose, a Quick Connect gun, a Vario Power lance, and a dirt blaster for removing stubborn dirt. The K 7 Power Flex is equipped with a water-cooled motor and was built for frequent cleaning and strong contamination, as one knows for instance from roads, swimming pools, bicycles or large cars. The extensive equipment package ranges from a pistol with a practical Quick Connect connection via a premium Flex high-pressure hose and a reliable water filter for protecting the pump to a Vario Power-spray pipe (VPS) as well as a dirt cutter with a rotating point jet. The pressure setting on the VPS can be changed literally in an instant, and the dirt mill makes even the most stubborn dirt. Other features include the Plug 'n' Clean cleaning agent system, the aluminum telescopic handle and the parking position for ready-to-use accessories.

FAQs
What type of water supply connection does this cleaner use?
The K 7 Power Flex requires a standard garden hose connection. The hose and tap adapter are not included and must be purchased separately.
How do I switch between cleaning modes (e.g., high pressure vs. detergent)?
You can switch between different spray patterns and pressure levels by rotating the Vario Power lance. For detergent application, use the 'MIX' setting on the lance and ensure the Plug 'n' Clean system is set up correctly.
Is the 10m hose long enough for most large driveways?
The 10-meter Premium Flex hose offers substantial reach and is generally sufficient for cleaning large driveways and other extensive outdoor areas without excessive repositioning of the pressure washer.
How often should I clean the water filter?
It is recommended to check and clean the integrated water filter periodically, especially if you are using a water source that may contain debris. Clean it after each use or if you notice a drop in performance.
Can I use any brand of cleaning agent?
While other detergents may work, Karcher recommends using Karcher Plug 'n' Clean detergents for optimal performance and to ensure compatibility with the system and the machine.
What is the advantage of a water-cooled motor?
A water-cooled motor is more durable and provides better heat dissipation during prolonged use, leading to a longer lifespan and more consistent performance, especially for demanding tasks.
How do I store the K 7 Power Flex during winter?
To prevent frost damage, fully drain all water from the machine, hoses, and lance. Store the unit in a frost-free location. Karcher often provides specific winterization instructions in the full manual.
Troubleshooting
No water pressure
Check water supply connection and ensure the tap is fully open. Verify the water filter is clean and correctly installed. Ensure the engine is primed by running water through the hose and lance before starting the motor.
Leaking connections
Ensure all hose connections (water supply, high-pressure hose) are securely tightened. Check O-rings on connections for damage and replace if necessary.
Motor stops during operation
Check for overheating; allow the unit to cool down. Ensure the power supply is stable and adequate. Check for blockages in the hose or lance.
Cleaning agent not being drawn
Verify the Plug 'n' Clean container is correctly inserted and filled. Ensure the correct setting is selected on the Vario Power lance for detergent application. Check the detergent tube for blockages.
