5. Operating Instructions

5.1 Dry Vacuuming

For dry vacuuming, ensure the flat-fold filter and a filter bag are correctly installed. Connect the power cord to a suitable electrical outlet. Press the power button to switch on the device. Move the floor nozzle or crevice nozzle over the surface to be cleaned. The powerful 1000W motor will effectively pick up dust, dirt, and debris.

5.2 Wet Vacuuming

Before wet vacuuming, remove the filter bag from the tank. The flat-fold filter is designed to handle both wet and dry dirt without needing to be removed. Connect the power cord and switch on the device. Carefully move the floor nozzle over the liquid spill. Do not overfill the 20-liter tank; monitor the liquid level. After wet vacuuming, it is crucial to clean the filter and allow it to air dry completely before subsequent use.

5.3 Blowing Function

To use the blowing function, disconnect the suction hose from the inlet port and connect it to the blowing port on the vacuum cleaner. This feature is useful for clearing leaves, light debris, or dust from hard-to-reach areas where vacuuming is not practical.

5.4 Filter Cleaning Technology

The Kärcher WD 4S V-20/5/22 features an integrated filter cleaning technology. To activate, locate the designated button or lever on the vacuum cleaner (refer to the device markings). Pressing this button will shake the filter, dislodging accumulated dust and restoring suction power without needing to open the tank.

6. Maintenance

6.1 Emptying the Container

Regularly empty the 20-liter stainless steel collection tank to maintain optimal performance. To do this, unlatch the clips securing the vacuum cleaner head, lift the head off the tank, and dispose of the collected contents. Reattach the head securely after emptying.

6.2 Filter Care

The flat-fold filter should be cleaned regularly. For dry dirt, gently tap the filter to dislodge dust. For wet dirt, rinse the filter with water. Ensure the filter is completely dry before reinstalling it for dry vacuuming. Replace the filter bag when it is full or when suction power noticeably decreases during dry vacuuming.

6.3 Accessory Storage

Utilize the integrated storage spaces on the vacuum cleaner for the suction hose, power cord, suction pipes, and nozzles. This keeps accessories organized, prevents loss, and ensures they are readily accessible for your next cleaning task.

7. Troubleshooting

• No Suction Power:
  • Check if the flat-fold filter is clogged and clean it using the integrated filter cleaning function or manually.
  • Ensure the filter bag (for dry vacuuming) is not full and replace if necessary.
  • Verify all hose connections are secure and airtight.
  • Check the suction hose and nozzles for any blockages and clear them.
• Vacuum Not Starting:
  • Ensure the power cord is securely plugged into a working electrical outlet.
  • Check the power switch for proper engagement.
  • If the motor overheats due to prolonged use or blockage, it may have a thermal cut-off. Allow the unit to cool down for approximately 30 minutes before attempting to restart.
• Water Leaking (during wet vacuuming):
  • Ensure the collection tank is not overfilled.
  • Verify that the vacuum cleaner head is properly seated and sealed onto the tank.
