Using your Cleanstar CSV001 filter set is easy. First, turn off and unplug your vacuum cleaner. Then, open the filter compartment and remove the old filters. Put in the new inner and outer filters from this set. Make sure they fit properly before closing the compartment. When it comes to maintenance, check the filters regularly. If they look dirty, take them out and gently tap them to remove large debris. You can also wash them with mild soapy water, but let them dry completely before putting them back in the vacuum. Remember, never use the vacuum without the filters in place, as this can damage the motor. Also, don't use harsh chemicals on the filters, as it can affect their performance.
