Selfpriming water inlet hose (5 meters): effectively draws water from the source without needing an additional pump, enabling quick setup and reliable supply for a range of cleaning tasks. Ideal when the water source is distant, such as a barrel, bucket, or distant faucet. Filtering capability: builtin filtration reduces impurities before they reach the pressure washer, helping prevent clogs and wear. Results in smoother operation and can contribute to longer machine life. Compatibility: designed for models K2 through K5, providing a precise fit and dependable performance across multiple machines in the range. Material and build: made from durable plastic with a design that allows easy monitoring of water flow, while withstanding pressure for extended use. Use scenarios: Car cleaning on a driveway using a distant water source (barrel or bucket); the selfpriming hose supplies water without an extra pump, while filtration protects the washer. Outdoor surface cleaning (patios, driveways) where debris is present; filtration helps prevent debris from reaching the unit, and flow can be visually monitored. Garage or workshop cleaning with K2K5 machines; quick, secure connection and reliable water supply from various sources without additional equipment.
