Using your Volta Vortex U4015F dust container is easy. First, make sure your vacuum is turned off and unplugged. Then, remove the old dust container and replace it with this new one. It should fit easily into place. When using the vacuum, the cone filter and HEPA filter will work together to trap dust and debris. As for maintenance, regularly check the filters. If they look dirty, you can gently clean the cone filter with a brush. The HEPA filter might need to be replaced after a certain amount of use, follow the manufacturer's instructions for that. Also, empty the dust container when it's about three - quarters full to keep the vacuum working at its best. Keep it in a dry place when not in use, and you'll enjoy a long - lasting and efficient cleaning experience.
