5.1 Filter Cleaning and Replacement

• HEPA Filter (Dry Vacuuming):

  The washable HEPA filter should be cleaned regularly, especially when suction power decreases. To clean, remove the filter from the motor head and tap it gently to dislodge dust. For thorough cleaning, rinse it under running water. Allow it to dry completely before reinstallation. Do not use the vacuum with a wet HEPA filter.

  

  Figure 5.1: Proper installation and removal of the HEPA filter for dry vacuuming.

• Foam Filter (Wet Vacuuming):

  The foam filter should be cleaned after each wet vacuuming session. Remove it from the motor head and rinse it thoroughly with water. Squeeze out excess water and allow it to air dry completely before storage or next use.

• Integrated Filter Cleaning System:

  The vacuum cleaner features an integrated system to clear accumulated dust from the filter during operation. Press the designated "PRESS" button on the motor head (refer to Figure 3.2) to activate this function, which helps maintain consistent suction power without interruption.

5.2 Tank Emptying and Cleaning

• Dry Debris: After dry vacuuming, unclip the motor head and carefully lift it off. Dispose of the collected dry debris from the tank. Wipe the inside of the tank with a damp cloth if necessary.
• Liquids: After wet vacuuming, unplug the unit. Position the vacuum over a drain or suitable container. Open the integrated drain valve at the bottom of the tank to empty the liquid. Rinse the tank with clean water and wipe dry.
