4. Setup
Follow these steps to assemble your Kärcher WD 2 Plus vacuum cleaner:
- Attach the Wheels: Insert the four wheels into the designated slots on the base of the vacuum cleaner until they click into place.
- Install the Filter: For both wet and dry vacuuming, ensure the cartridge filter is correctly installed. Open the vacuum head, place the cartridge filter onto the motor unit, and secure it according to the markings.
- Insert Filter Bag (for dry vacuuming): For dry vacuuming, insert the fleece filter bag into the tank, ensuring the opening aligns with the suction inlet.
- Attach the Suction Hose: Connect the suction hose to the suction inlet on the front of the vacuum cleaner. Ensure it is securely fastened.
- Assemble Suction Tubes and Nozzle: Connect the two suction tubes together, then attach them to the end of the suction hose. Finally, attach the desired nozzle (e.g., floor nozzle or crevice nozzle) to the end of the suction tubes.
5. Operation
The Kärcher WD 2 Plus is designed for ease of use. Familiarize yourself with its functions:
5.1 Switching On/Off
To switch the appliance on or off, turn the rotary switch located on the top of the vacuum cleaner to the 'ON' or 'OFF' position respectively.
5.2 Wet Vacuuming
For wet vacuuming, ensure the cartridge filter is installed. Do not use a filter bag. The appliance will collect liquids directly into the 12-liter PVC tank. When the tank is full, the float will rise and interrupt the suction. Switch off the appliance and empty the tank.
5.3 Dry Vacuuming
For dry vacuuming, use the fleece filter bag in conjunction with the cartridge filter. The filter bag collects fine dust and debris, protecting the cartridge filter and ensuring optimal suction performance.
5.4 Blower Function
The WD 2 Plus features a convenient blower function. To activate, detach the suction hose from the front inlet and connect it to the blower outlet located on the rear of the vacuum head. This function is useful for clearing leaves from gravel beds or blowing dust from hard-to-reach areas.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your vacuum cleaner.
6.1 Emptying the Tank
After wet vacuuming, or when the tank is full during dry vacuuming, switch off the appliance and unplug it. Detach the vacuum head and carefully empty the contents of the 12-liter PVC tank. Clean the tank with water if necessary.
6.2 Filter Maintenance
The cartridge filter is designed for both wet and dry use without needing to be changed. However, it should be cleaned regularly to maintain suction power. Remove the filter and tap out any accumulated dust. For thorough cleaning, the filter can be rinsed under running water and allowed to dry completely before reinstallation.

The fleece filter bag should be replaced when full or when suction power decreases significantly during dry vacuuming. Do not attempt to clean and reuse fleece filter bags as their filtration efficiency may be compromised.
