Using this Volta Tornado Gen3 U4009 filter set is easy. First, turn off and unplug your vacuum cleaner. Then, locate the filter compartment. Remove the old filters and replace them with the new Hepa and Micromesh filters. Make sure they fit snugly. When using the vacuum, avoid vacuuming large or sharp objects that could damage the filters. For maintenance, check the filters regularly. If the Micromesh filter gets dirty, you can gently wash it with water and let it dry completely before reinstalling. The Hepa filter, however, is not washable. If it becomes clogged or damaged, replace it. This way, your vacuum cleaner will keep working at its best.
