Using these Vax GENIE filters is easy. First, turn off your Vax GENIE handheld vacuum cleaner and unplug it from the power source. Then, locate the filter compartment. Open it and remove the old filter. Take one of the new filters from the pack and place it in the compartment. Make sure it fits snugly. Close the compartment and you're ready to go. When it comes to maintenance, it's a good idea to check the filter regularly. If it looks dirty or clogged, it's time to replace it with a new one from the pack. Always use genuine Vax parts like these filters to ensure the best performance of your vacuum cleaner. And remember, before any maintenance work, always turn off and unplug the vacuum to avoid any accidents.
