Using your Volta MobiOne or Zanussi vacuum cleaner with this filter set is easy. First, turn off and unplug the vacuum cleaner. Then, open the filter compartment and remove the old filters. Place the new Hepa, micromesh, and foam filters in their respective slots. Make sure they fit snugly. When it comes to maintenance, the Hepa and foam filters are washable. Simply remove them from the vacuum, rinse them under lukewarm water until the water runs clear, and let them dry completely before reinstalling. The micromesh filter can be gently tapped to remove dust or replaced when it gets too dirty. Remember, always turn off the vacuum before handling the filters to avoid any electrical hazards.
