Using these vacuum cleaner bags is easy. Just open the pack and replace the old bag in your Hako RocketVac XP backpack vacuum cleaner with a new one. Make sure it's properly installed so it can work effectively. When it comes to maintenance, check the bag regularly. If it's full or clogged, replace it right away. This will keep your vacuum cleaner working well. Also, store the unused bags in a dry place to maintain their quality. Avoid using the bags if they are damaged as this may affect the performance of your vacuum cleaner and lead to poor filtration.
