Using your Volta MobiMaxx U3510 dust container is a breeze. First, make sure your vacuum is turned off and unplugged before you start handling the container. Simply remove the old container and replace it with this new one. It's designed to fit easily, so you won't have any trouble getting it in place. When using the vacuum, keep an eye on the dust level in the container. Once it's about three - quarters full, it's time to empty it. To empty, take the container out, open the bottom lid, and shake the dust into a trash can. For maintenance, clean the cone filter and HEPA filter regularly. You can gently tap the cone filter to remove large debris, and for the HEPA filter, follow the manufacturer's instructions on cleaning. If you notice any damage to the container or filters, replace them right away. Always store the container in a dry place when not in use.
