- Fully tighten the spray head by twisting it clockwise.
- Fill the spray bottle with the Kärcher window cleaner concentrate mixed with water, up to the 'max' fill line.

Operating Instructions
Follow these steps for effective cleaning with your Kärcher WV 1 Plus:
- Prepare the Surface: Using the assembled spray bottle, generously mist the surface you intend to clean with the cleaning solution. Ensure the entire area is covered.
- Clean the Surface: Use the microfiber pad on the spray bottle to wipe away dirt and grime from the surface. This step loosens and lifts the dirt.
- Vacuum the Solution: Turn on the Kärcher WV 1 Plus by pressing the power button. Hold the device with the squeegee blade flat against the surface and draw it downwards in a smooth, continuous motion. The built-in vacuum will suction the dirty cleaning solution into the reservoir, leaving the surface dry and streak-free.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your Kärcher WV 1 Plus.
Emptying and Cleaning the Dirt Water Tank
After each use, or when the tank reaches its maximum fill line, empty the dirty water tank. Detach the tank from the main unit and pour out the contents. Rinse the tank thoroughly with clean water to remove any residue. Ensure it is completely dry before reattaching.
Cleaning the Microfiber Pad
The microfiber pad is machine-washable. Remove it from the spray bottle and wash it according to the care instructions, typically with similar colors and without fabric softener. Allow it to air dry completely before reattaching or storing.
Maintaining the Squeegee Blade
Periodically inspect the rubber squeegee blade for any debris, nicks, or wear. Small particles on the blade can lead to streaks. Wipe the blade with a clean, damp microfiber cloth to ensure it is free of dirt and smooth for optimal performance. If the blade is damaged, replacement blades are available from Kärcher.
