Using these vacuum cleaner bags is easy. First, turn off and unplug your Hoover vacuum cleaner. Open the bag compartment as per your vacuum's instructions. Remove the old bag carefully and discard it. Take one of the new Cleanstar bags from the pack. Insert it into the compartment, making sure it fits snugly and the opening aligns properly. Close the compartment and you're ready to start vacuuming. When it comes to maintenance, check the bag regularly. If it looks full or the vacuum's suction power decreases, it's time to replace the bag. Also, keep the bags in a dry place to prevent any damage. Don't try to reuse the disposable bags as it may affect the vacuum's performance and increase the risk of allergens being released back into the air.
